Glossary of Terms (5)I.High Speed Fiber Photodetector OverviewThe High Speed Fiber Photodetectors contain PIN photodiodes that utilize the photovoltaic effect to convert optical power into an electrical current. Figure 1 below identifies the main elements of your Fiber Photodetector.Figure 1: High Speed Fiber PhotodetectorWhen terminated into 50Ω into an oscilloscope, the pulsewidth of a laser can be measured. When terminated into a spectrum analyzer, the frequency response of a laser can be measured.II.Operation of your High Speed Fiber PhotodetectorA. Caution: Eye safety precautions must be followed when utilizing any equipment used in the vicinityof laser beams. Laser beams may reflect from the surface of the detector or the optical mount and caution must be exercised.B. Clean the end of the fiber ferrule and connect to the laser.C. Adjust the voltage of the oscilloscope to 50mV/division before connecting the detector.Power Switch3mm Furcation TubingBootSMA ConnectorD.Connect the detector to the oscilloscope using a coaxial cable designed for 10GHz operation.e the 50Ω termination input of the oscilloscope.F.After being certain that the damage threshold of the detector is not exceeded, turn on the laser.G.There is an internal 50Ωresistor at the output of the photodiode. This will cause the output current toyour test equipment to be half that of the photodiode output. For example, the output to yourequipment will be 450µA for a 1mW optical input at 0.9A/W. Some losses will also exist in the fibercable and connectors.III.TroubleshootingA.No signal is seen the first time the detector is used.1.Is the power switch on?2.Be certain that the signal is not high off scale on the oscilloscope.3.Is the wavelength of the laser within the spectral range of the detector?4.Has a 50Ω termination input been used?5.Make sure the fiber radius is greater than 1 inch. Inspect fiber for damage.6.Is there enough light (see sensitivity spec on the data sheet) incident on the detector to generate asignal?B. A signal has been previously obtained, but not currently.1.Try steps listed under A.2.Test the power supply:a.Units with internal batteries will typically operate for several years, but operation with CWor high rep rate lasers can drain the batteries much faster. If a load is present at the output,current will be drawn from the batteries, so disconnect the BNC when not in use.Remove top cover to replace the 3V lithium cells with Duracell Model DL2430, positive sidedown.b.Units with an external power supply should at least receive the voltage that is printed on theplug.C.Increasing the power incident on the detector does not result in a higher voltage signal on theoscilloscope:1.The detector is probably saturated. You should lower the power incident on the detector to alevel below the saturation point.IV.Drawings: High Speed Fiber PhotodetectorsA. 818-BB-35F, 818-BB-45F, 818-BB-51F Dimensions:V.Specifications: High Speed Fiber PhotodetectorsPart No. (Model) - Battery Bias 818-BB-35F 818-BB-45F 818-BB-51FRise Time/Fall Time (ps) <25/<25 <30/<30 28 Responsivity (A/W) >0.65 at 1300nm 0.38 at 830nm 0.95 at 2000nm Power Supply6V battery/5V external3V battery/5V external3V battery/5V externalSpectral Range (nm)830-1650 500-890 830-2150 Bandwidth>15GHz >12.5GHz>12.5GHzActive Area Diameter (µm) 32 60 40 Dark Current<3nA <0.5nA <1µA Noise Equivalent Power (pW/√Hz) <0.05 at 1300nm <0.03 at 830nm <0.6 at 2000nm Mounting (Tapped Hole) 8-32 or M4 8-32 or M4 8-32 or M4 Output Connector SMA SMA SMA Fiber Optic ConnectionFC/UPC, SMF 28eFC/UPC, SMF 28eFC/UPCVI. Schematics: High Speed Fiber PhotodetectorsVII. Glossary of TermsBandwidth: The range of frequencies from 0Hz (DC) to the frequency at which the amplitude decreases by 3dB. Bandwidth and rise time can be approximately related by the equation: Bandwidth ≈ 0.35/rise time for a Gaussian pulse input.Bias Voltage: The photodiode ’s junction capacitance can be modified by applying a reverse voltage. The bias voltage reduces the junction capacitance, which causes the photodiode to have a faster response.Dark Current: When a termination is present, a dark current (nA range) will flow if the photodiode is biased. Disconnecting the coaxial cable will prevent this current from flowing.Decoupling Capacitor: Maintains bias voltage when fast pulses cause the battery voltage to reduce (this would slow the response time of the photodiode ); the capacitor allows the battery to recover to its initial voltage. It also acts as a filter for external power supplies.Noise Equivalent Power (NEP): A function of responsivity and dark current and is the minimum optical power needed for an output signal to noise ratio of 1. Dark current is the current that flowsthrough a reverse biased photodiode even when light is not present, and is typically on the order of nA. Shot noise (Ishot) is a source of noise generated in part by dark current; in the case of reversed biased diodes it is the dominant contributor. NEP is calculated from shot noise and responsivity. For example, for a responsivity @ 830nm = 0.5 A/W:q = charge on an electronPhotodiode: Converts photons into a photocurrent.Resistor: Protects the photodiode from excessive current. This could occur if an external power supply was too high in voltage, or if its polarity were reversed; this happens when a customer uses their own power supply.Responsivity: In amps per watt (A/W), responsivity is the current output of the photodiode for a given input power, and is determined by the diode structure. Responsivity varies with wavelength and diode material.Rise time/Fall time: Rise Time is the time taken by a signal to change from a specified low value to a specified high value. Fall Time is the time taken for the amplitude of a pulse to decrease from a specified value to another specified value. A larger junction capacitance will slow the detector’s response time.SMA Connector: Used to connect the customer’s coaxial cable for high frequencies.Termination Resistor (50Ω): Reduces signal reflections and balances the 50Ω microstrip/coaxial cable lines. As a result, half the photodiode current is lost to the internal resistor.Hz 0.08pA/s 0.08pA )1020)(2(1.6x10=2_9-19===−A x As qI Noise Shot d Hz 0.16pW/0.5AW *08.0/R 830nm ===Hz pA I NEP shot。
光纤放大器的调节方法
光纤放大器的调节方法本页仅作为文档封面，使用时可以删除This document is for reference only-rar21year.March光纤放大器的调节方法无线光通信是以激光作为信息载体，是一种不需要任何有线信道作为传输媒介的通信方式。
与微波通信相比，无线光通信所使用的激光频率高，方向性强(保密性好)，可用的频谱宽，无需申请频率使用许可;与光纤通信相比，无线光通信造价低，施工简便、迅速。
它结合了光纤通信和微波通信的优势，已成为一种新兴的宽带无线接人方式，受到了人们的广泛关注。
但是，恶劣的天气情况，会对无线光通信系统的传播信号产生衰耗作用。
空气中的散射粒子，会使光线在空间、时间和角度上产生不同程度的偏差。
大气中的粒子还可能吸收激光的能量，使信号的功率衰减，在无线光通信系统中光纤通信系统低损耗的传播路径已不复存在。
大气环境多变的客观性无法改变，要获得更好更快的传输效果，对在大气信道传输的光信号就提出了更高的要求，一般地，采用大功率的光信号可以得到更好的传输效果。
随着光纤放大器(EDFA)的迅速发展，稳定可靠的大功率光源将在各种应用中满足无线光通信的要求。
1 、EDFA的原理及结构掺铒光纤放大器(EDFA)具有增益高、噪声低、频带宽、输出功率高、连接损耗低和偏振不敏感等优点，直接对光信号进行放大，无需转换成电信号，能够保证光信号在最小失真情况下得到稳定的功率放大。
、 EDFA的原理在掺铒光纤中注入足够强的泵浦光，就可以将大部分处于基态的Er3+离子抽运到激发态，处于激发态的Er3+离子又迅速无辐射地转移到亚稳态。
由于 Er3+离子在亚稳态能级上寿命较长，因此很容易在亚稳态与基态之间形成粒子数反转。
当信号光子通过掺铒光纤时，与处于亚稳态的Er3+离子相互作用发生受激辐射效应，产生大量与自身完全相同的光子，这时通过掺铒光纤传输的信号光子迅速增多，产生信号放大作用。
Er3+离子处于亚稳态时，除了发生受激辐射和受激吸收以外，还要产生自发辐射(ASE)，它造成EDFA的噪声。

This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing and fully calibrated output signals with a typical accuracy of 15% within measured values. The SGP combines multiple metal-oxide sensing elements on one chip to provide more detailed air quality signals.This is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile OrganicCompound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) overI2C.The SGP30 has a 'standard' hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage, tracks the baseline calibration, calcluates TVOC and eCO2 values, and provides an I2C interface to read from. Unlike the CCS811, this sensor does not require I2C clock stretching. Array This part will measure eCO2 (equivalent calculated carbon-dioxide) concentrationwithin a range of 400 to 60,000 parts per million (ppm), and TVOC (Total VolatileOrganic Compound) concentration within a range of 0 to 60,000 parts perbillion (ppb).Please note, this sensor, like all VOC/gas sensors, has variability and to get precise measurements you will want to calibrate it against known sources! That said, for general environmental sensors, it will give you a good idea of trends and comparison. The SGP30 does have built in calibration capabilities, note that eCO2 is calculated based on H2 concentration, it is not a 'true' CO2 sensor for laboratory use.Another nice element to this sensor is the ability to set humidity compensation for better accuracy. An external humidity sensor is required and then the RH% is written over I2C to the sensor, so it can better calculate the TVOC/eCO2 values.Nice sensor right? So we made it easy for you to get right into your next project. The surface-mount sensor is soldered onto a custom made PCB in the STEMMA QT form factor (), making them easy to interface with. The STEMMA QT connectors () on either side are compatible with the SparkFun Qwiic () I2C connectors. This allows you to make solderless connections between your development board and the SGP30 or to chain it with a wide range of other sensors and accessories using a compatible cable ( ).We’ve of course broken out all the pins to standard headers and added a 1.8V voltage regulator and level shifting so allow you to use it with either 3.3V or 5V systems suchas the Raspberry Pi, or Metro M4 or Arduino Uno.PinoutsPower Pins:Vin - this is the power pin. Since the sensor chip uses 3 VDC for logic, we have included a voltage regulator on board that will take 3-5VDC and safely convert it down. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V1V8 - this is the 1.8V output from the voltage regulator, you can grab up to 50mA from this if you likeGND - common ground for power and logicData PinsSCL - I2C clock pin, connect to your microcontrollers I2C clock line. Can use 3V or 5V logic, and has a 10K pullup to VinSDA - I2C data pin, connect to your microcontrollers I2C data line. Can use 3V or 5V logic, and has a 10K pullup to VinSTEMMA QT () - These connectors allow you to connectors to dev boards with S TEMMA QT connectors or to other things with various associated accessories ()Arduino TestYou can easily wire this breakout to any microcontroller; we'll be using an Arduino.• • • • • •Start by soldering the headers to the SGP30 breakout board. Check out the Adafruit guide to excellent soldering () if you're new to soldering. Then continue on below to learn how to wire it to a Metro.The sensor uses I2C address 0x58 and cannot be changed.WiringConnect the SGP30 breakout to your board using an I2C connection. Here's an example with an Arduino-compatible Metro:Board 5V to Sensor Vin (red wire onSTEMMA QT version). (Metro is a 5V logicchip)Board ground / GND to sensor ground /GND (black wire on STEMMA QT version).Board SCL to sensor SCL (yellow wire onSTEMMA QT version).Board SDA to sensor SDA (blue wire onSTEMMA QT version).Metro Original Fritzing FileInstall Adafruit_SGP30 libraryTo begin reading sensor data, you will need to install the Adafruit_SGP30 library (code on our github repository) (). It is available from the Arduino library manager so we recommend using that.From the IDE open up the library manager...And type in adafruit sgp30 to locate the library. Click InstallLoad DemoOpen up File->Examples->Adafruit_SGP30->sgp30test and upload to your microcontroller wired up to the sensorThen open up the serial console at 115200 baud, you'll see the serial number printed out - this is a unique 48-bit number burned into each chip. Since you may want to doper-chip calibration, this can help keep your calibration detail separateThe first 10-20 readings will always be TVOC 0 ppb eCO2 400 ppm. That's because the sensor is warming up, so it will have 'null' readings.After a few seconds, you will see the TVOC and eCO2 readings fluctuate: ArrayEvery minute or so you'll also get a Baseline value printed out. More about that later!You can take a bit of alcohol on a swap and swipe it nearby to get the readings tospikeThat's it! The sensor pretty much only does that - all the calculations for the TVOC and eCO2 are done within the sensor itself, no other data is exposed beyond the'baseline' valuesBaseline Set & GetAll VOC/gas sensors use the same underlying technology: a tin oxide element that, when exposed to organic compounds, changes resistance. The 'problem' with these sensors is that the baseline changes, often with humidity, temperature, and other non-gas-related-events. To keep the values coming out reasonable, you'll need to calibrate the sensor.If no stored baseline is available after initializing the baseline algorithm,the sensor has to run for 12 hours until the baseline can be stored. This willensure an optimal behavior for the next time it starts up. Reading out thebaseline prior should be avoided unless a valid baseline is restored first.Once the baseline is properly initialized or restored, the current baselinevalue should be stored approximately once per hour. While the sensor isoff, baseline values are valid for a maximum of seven days.Restarting the sensor without reading back a previously stored baselinewill result in the sensor trying to determine a new baseline. Theadjustement algorithm will be accelerated for 12hrs which is the Maximumtime required to find a new baseline.The sensor adjusts to the best value it has been exposed to. So keeping itindoors the sensor thinks this is the best value and sets it to ~0ppb tVOCand 400ppm CO2eq. As soon as you expose the sensor to outside air itcan adjust to the global H2 Background Signal. For normal Operationexposing the sensor to outside air for 10min cumulative time should besufficient.If you're experienced with sensors that don't have a baseline, you eitherwon't be able to measure absolute values or you'll have to implement yourown baseline algorithm.The sensor to sensor variation of SGP30 in terms of sensitivity is very goodas each of them is calibrated. But the baseline has to be determined foreach sensor individually during the first Operation.To make that easy, SGP lets you query the 'baseline calibration readings' from the sensor with code like this:uint16_t TVOC_base, eCO2_base;sgp.getIAQBaseline(&eCO2_base, &TVOC_base);This will grab the two 16-bit sensor calibration words and place them in the variables so-named.You should store these in EEPROM, FLASH or hard-coded. Then, next time you start up the sensor, you can pre-fill the calibration words withsgp.setIAQBaseline(eCO2_baseline, TVOC_baseline); Arduino Library DocsArduino Library Docs ()Python & CircuitPython TestIt's easy to use the SGP30 sensor with Python or CircuitPython and the Adafruit CircuitPython SGP30 () module. This module allows you to easily write Python code that reads the TVOC, eCO2, and more from the sensor.You can use this sensor with any CircuitPython microcontroller board or with a computer that has GPIO and Python thanks to Adafruit_Blinka, our CircuitPython-for-Python compatibility library ().CircuitPython MicroController Wiring Connect the SGP30 breakout to your board using an I2C connection, exactly as shown on the previous page for Arduino.

Our introduction guide has a great page on how to install the library bundle () for both express and non-express boards.Remember for non-express boards like the, you'll need to manually install the necessary libraries from the bundle:adafruit_sgp30.mpyadafruit_bus_deviceYou can also download the adafruit_sgp.mpy from its releases page on Github ().Before continuing make sure your board's lib folder or root filesystem has the adafruit _sgp30.mpy, and adafruit_bus_device files and folders copied over.Next connect to the board's serial REPL ()so you are at the CircuitPython >>> prompt.Python Installation of SGP30 LibraryYou'll need to install the Adafruit_Blinka library that provides the CircuitPythonsupport in Python. This may also require enabling I2C on your platform and verifying you are running Python 3. Since each platform is a little different, and Linux changes often, please visit the CircuitPython on Linux guide to get your computer ready ()!Once that's done, from your command line run the following command:sudo pip3 install adafruit-circuitpython-sgp30If your default Python is version 3 you may need to run 'pip' instead. Just make sure you aren't trying to use CircuitPython on Python 2.x, it isn't supported!• • •CircuitPython & Python UsageTo demonstrate the usage of the sensor we'll initialize it and read the eCO2 and TVOC data and print it to the REPLSave this example sketch as main.py on your CircuitPython board:# SPDX-FileCopyrightText: 2021 ladyada for Adafruit Industries# SPDX-License-Identifier: MIT""" Example for using the SGP30 with CircuitPython and the Adafruit library""" import timeimport boardimport busioimport adafruit_sgp30i2c = busio.I2C(board.SCL, board.SDA, frequency=100000)# Create library object on our I2C portsgp30 = adafruit_sgp30.Adafruit_SGP30(i2c)print("SGP30 serial #", [hex(i) for i in sgp30.serial])sgp30.set_iaq_baseline(0x8973, 0x8AAE)sgp30.set_iaq_relative_humidity(celsius=22.1, relative_humidity=44)elapsed_sec = 0while True:print("eCO2 = %d ppm \t TVOC = %d ppb" % (sgp30.eCO2, OC))time.sleep(1)elapsed_sec += 1if elapsed_sec > 10:elapsed_sec = 0print("**** Baseline values: eCO2 = 0x%x, TVOC = 0x%x"% (sgp30.baseline_eCO2, sgp30.baseline_TVOC))In the REPL you'll see the serial number printed out: [0x0, 0x64, 0xb878] in this case.

光纤放大器的调节方法.docx
光纤放大器的调节方法无线光通信是以激光作为信息载体，是一种不需要任何有线信道作为传输媒介的通信方式。
与微波通信相比，无线光通信所使用的激光频率高，方向性强( 保密性好 ) ，可用的频谱宽，无需申请频率使用许可;与光纤通信相比，无线光通信造价低，施工简便、迅速。
它结合了光纤通信和微波通信的优势，已成为一种新兴的宽带无线接人方式，受到了人们的广泛关注。
但是，恶劣的天气情况，会对无线光通信系统的传播信号产生衰耗作用。
空气中的散射粒子，会使光线在空间、时间和角度上产生不同程度的偏差。
大气中的粒子还可能吸收激光的能量，使信号的功率衰减，在无线光通信系统中光纤通信系统低损耗的传播路径已不复存在。
大气环境多变的客观性无法改变，要获得更好更快的传输效果，对在大气信道传输的光信号就提出了更高的要求，一般地，采用大功率的光信号可以得到更好的传输效果。
随着光纤放大器(EDFA)的迅速发展，稳定可靠的大功率光源将在各种应用中满足无线光通信的要求。
1、 EDFA的原理及结构掺铒光纤放大器(EDFA)具有增益高、噪声低、频带宽、输出功率高、连接损耗低和偏振不敏感等优点，直接对光信号进行放大，无需转换成电信号，能够保证光信号在最小失真情况下得到稳定的功率放大。
、 EDFA 的原理在掺铒光纤中注入足够强的泵浦光，就可以将大部分处于基态的Er3+ 离子抽运到激发态，处于激发态的 Er3+ 离子又迅速无辐射地转移到亚稳态。
由于Er3+离子在亚稳态能级上寿命较长，因此很容易在亚稳态与基态之间形成粒子数反转。
当信号光子通过掺铒光纤时，与处于亚稳态的Er3+ 离子相互作用发生受激辐射效应，产生大量与自身完全相同的光子，这时通过掺铒光纤传输的信号光子迅速增多，产生信号放大作用。
Er3+离子处于亚稳态时，除了发生受激辐射和受激吸收以外，还要产生自发辐射(ASE) ，它造成EDFA 的噪声。
、 EDFA 的结构典型的EDFA结构主要由掺铒光纤(EDF)、泵浦光源、耦合器、隔离器等组成。

GigMaster 30 管理指南 管道电子吉他放大器说明书
Operator's ManualTube Guitar AmplifierPlease, first read this manual carefully!GigMaster 30Front Panel FeaturesGigMaster 30. This compact tube-driven amp delivers to-die-for tone in a phenomenally portable package! Either version, Combo or Head, is your perfect sidekick for playing gigs, recording in studios, and practicing at home. It comes loaded with a bevy of convenient sound-sculpting features designed to make your musical life easier and more rewarding, including a built-in spring reverb, Gain Boost, and Master Volume Boost. This M.V.B. lets you access two different master volume levels on the fly via footswitch, for example, one for rhythm and the other for leads.Four EL84 pentode power tubes serve up the amp's sweet fundamental sound, while the preamp's ECC83 double triode dishes out lashings of overdrive and distortion. What's more, the GigMaster 30 sports two channels, Clean and Lead, to give you an even wider variety of tonal flavors. And its Mid Boost switch accentuates those middle frequencies that mean so much to the sound of an electric guitar. Six sound-shaping may be controlled remotely via footswitch, which gives you lots of tonal flexibility paired with utmost handling ease! This ingenious little amp is sure to delight with its warm, bluesy tone and assertive mids. But don't take our word for it - plug in, play, and enjoy!You'll find guidelines on care and maintenance of tube amps handling in certain places of this manual. Please read and heed these before operating your amp. You'll also come across boxes shaded grey throughout the manual. These are located between the descriptions of the amp's functions and contain handy tips on the preceding function. All critical information pertaining to the operation of this amp is preceded by "NOTE" or "CAUTION." Please pay particular attention to these safety tips. The ENGL team wishes you all the best —may you and your amp enjoy a "harmonically rich" future together!1 Input: ¼" unbalanced input jack. Plug your guitar in here using a shielded cord.2 Input Gain: This knob controls the preamp's input sensitivity. Use to dial in the desired amount of gain for the Clean and Lead channels. It and the Master (12) knob determine the Clean channel's amount of preamp distortion in Lead mode.Note: The amp's noise floor will increase appreciably if you crank both the Lead Drive and Input Gain knobs!CAUTION: Extremely high gain and volume levels in Lead mode can produce powerful feedback. Avoid feedback squeals; they can lead to hearing loss and damage speakers! At higher volumes, 5 Middle: Mid-range voicing control of the preamps ´s passive EQ.7 Reverb: Reverb intensity knob. Twist it to adjust the amount of reverb for Clean and Lead. Turn the Reverb control knob clockwise to increase the effect's intensity. The signal remains completely dry when the knob is set to the 7 o'clock position or if Reverb is deactivated via a footswitch. You can switch the reverb unit on and off using a footswitch connected to jack 18. The reverb unit is always on if you do not plug a footswitch into jack 18.8 Lead Volume: Volume control for the Lead channel (pre-FX loop, influences the Send level).The red LED above the channel switching selector (11) indicates Lead operating mode.Use this knob to dial in the desired balance of levels between the Lead and Clean channels.9 Mid Boost: This voicing feature operates globally, affecting both channels by boosting specificmidrange frequencies when activated. The LED above the button lights up to indicate Mid Boostis activated. It may also be switched using a footswitch connected to jack 19.above the button lights up to indicate Gain Boost is engaged. You can also control Gain BoostThis function can also be activated via the respective footswitch connected to jack 20.Once a footpedal is connected, the channel selector pushbutton is deactivated.12 Master: This master volume knob controls the power amp's output (it is located post FX Loop).M.V.B. (Master Volume Boost): This feature increases the master volume level, giving you instant access to two different volume levels for different musical situations, for instance, one for rhythm parts and the other for lead lines.You can control this feature via a footswitch connected to port 19.13 Power Tube Fuse: This red LED lights up to indicate one of the internal power tube fuses hasblown. You can continue playing, but the amp's performance will be diminished. Normally theloss of a power tube results in an unbalanced signal.Be sure to have a specialist look over the power amp as soon as possible; the fuse probably blew because of a defective power tube. Once a fuse has blown, it must be replaced by a new fuse.14 Stand By: Power amp standby switch: Use this switch to silence (0 position) the amp when youtake a break. The amp's tubes stay warm, which means that it is ready to roll immediatelywhen you switch it back to full power. The standby switch is also well-suited for muting the ampPlease note: ensure that the Stand By switch (14) is set to Stand By (0 position) before you switch the amp on. Let the tubes heat up for about 30 seconds before you activate the power amp. This procedure spares the tubes.CAUTION: After an extended period of operation and higher ambient temperatures the amps'schassis can become very hot, therefore avoid touching the rear panel surface !16 Mains Connector (AC Power Inlet; IEC - C14 connector)Plug the mains cord in here. For European models, use a standard non-heating equipment connector cable.CAUTION: Make sure you use an intact mains line cord with a grounded plug! Before you power the amp up, ensure the voltage value printed alongside the mains socket is the same as the current of the local power supply or wall outlet.Please also heed the guidelines set forth in the separately included pamphlet, Instructions for the Prevention of Fire, Electrical Shock and Injury.17 Mains Fuse Box: The rear chamber contains the mains fuse and in the front chamber, a spare fuse. CAUTION: ALWAYS make sure replacement fuses are of the same type and have the same ratings as the original fuse! Please refer to the fuse ratings table.18 Footswitch FX Off/On; Reverb: Use this ¼" Stereo jack to connect a conventional footswitch with two switching functions, for example, the ENGL Z-4 (2 x off/on - Single Pole Single Throw or SPST for short). This type of footswitch lets you switch the FX Loop and Reverb off and on. One of the two switches activates the FX Loop; the other engages the internal Reverb.The FX Loop and the Reverb system are activated by default if you do not connect a footswitch to this jack. Note also that a footswitch may be equipped with LEDs indicating the given switching status. Each of the two switches is provided with about 10 milliamperes of current, which suffices to power a standard LED. The jack's mono terminal (the tip) switches the FX Loop off and on, and the stereo terminal (the ring) switches Reverb off and on. For pin assignments, see "Wiring of Principal Connectors".19 Footswitch Mid Boost; M.V.B. (Master Volume Boost): Use this ¼" Stereo jack to connect a conventional footswitch with two switching functions, for example, the ENGL Z-4 (2 x off/on - Single Pole Single Throw or SPST for short).One of the two switches activates Mid Boost; the other engages Master Volume Boost.Plugging a footswitch into this jack disables onboard Mid Boost (9) switching. Note also that a footswitch may be equipped with LEDs indicating the given switching status. Each of the two switches is provided with about 10 milliamperes current, which suffices to power a standard LED. The jack's mono terminal (the tip) switches Mid Boost, while the stereo terminal (the ring) switches M.V.B. For pin assignments, see "Wiring of Principal Connectors".20 Footswitch Clean/Lead; Gain Boost: Use this ¼" Stereo jack to connect a conventional footswitch with two switching functions, for example, the ENGL Z-4 (2 x off/on - Single Pole Single Throw or SPST for short). This type of footswitch lets you access the two channels and Gain Boost. One of the two switches activates Clean or Lead; the other engages Gain Boost.Plugging a footswitch into this jack disables onboard channel (11) and Gain Boost (10) switching. Note also that a footswitch may be equipped with LEDs indicating the given switching status. Each of the two switches is provided with about 10 milliamperes current, which suffices to power a standard LED. The jack's mono terminal (the tip) selects Clean or Lead, while the stereo terminal shortest possible shielded cord equipped with ¼" plugs.22 FX Loop Return: Use a shielded cord equipped with ¼" jack plugs to connect an effects device's output or send jack to this input. You can control the FX Loop remotely via a footswitch connected to port 18. The FX Loop is active (on) by default when no footswitch is connected to port 18. Remark: The FX Loop is located between the preamp and power amp in the signal path. Inserting a ¼" jack plug into the Return port interrupts the circuit between the preamp and power amp.Rear Panel Features23 Line Out - 0 dB Poweramp Signal: This port taps the power amp's output to provide a line out signal configured at a level of about 0 dB. The frequency response is identical to that of the power amp output signal. In other words, its frequency response has not been compensated or corrected.You can feed this signal to another linear power amp. Another option is to patch it through an outboard filter to emulate a speaker, for example, a 4x12 cabinet simulation, and feed this externally processed signal to a recording device or PA system.24 Poweramp Output 8 Ohms, internal speaker: This 8-ohm speaker out is wired in parallel with port 25. Connect an 8-ohm cabinet or, in the case of the E300 Combo, its internal speaker to it.25 Poweramp Output 8 Ohms parallel: This 8-ohm speaker out is wired in parallel with port 24. Use it in combination with port 24 to connect two 16-ohm cabinets.26 Poweramp Output A -16 Ohms serial: 16-ohm speaker out, connected internally in series withOutput B (jack 27). Connect a 16-ohm cabinet here (Output A). Two 8-ohm speakers are connected to Output A (jack 26) and Output B (jack 27), for example a combination of the internal 8-ohm speaker of the Combo E300 and an external 8-ohm cabinet, e.g. the ENGL models E112 or E412. CAUTION: If you intend to use a 16-ohm cabinet only, make absolutely certain you connect it to Output A (jack 26).Output B (jack 27) is only enabled when a speaker is connected to Output A (jack 20).27 Poweramp Output B - 16 Ohms serial: This is an auxiliary output connected in series with Output A (jack 26). This output is designed for one application for only —when you are driving a combination of two 8-ohm cabinets/speakers. This output may only be used when an 8-ohm speaker is connected to Output A (jack 26).NOTE: Never operate the amplifier without a sufficient load, otherwise you may damage or destroy the power amp!Speaker/ cabinet options:You can connect one 8-ohm cabinet (or the Combo's internal speaker) to the 8-Ohm Output (24); or two 16-ohm cabs to the two 8-Ohm Outputs (ports 24 and 25); or one 16-ohm cab to Output A (port 26);or two 8-ohm cabs to Output A and B (ports 26 and 27).Tube array:Reverb Connector:red plug:reverb spring inputblack plug:reverb spring outputHandling and Care* Keep the amp safe from hard knocks and shocks. Tubes are fragile and tend to suffer when exposed to mechanical stress!* Let the amp cool down before you transport it. Ten minutes or so will spare the tubes.* Tubes take some 20 seconds to warm up after you switch the power on, andabout two to three minutes before they are able to pump out full power. Make a habit of giving your amp plenty of time to get toasty and flipping the Standby switch for short breaks.* In order to spare the power tubes and prolong their lifetime, we recommend to set theStand By switch to Stand By (0 position, that is) before you switch the amp on. After a period of 30 seconds you may activate the poweramp by flipping the Stand By switch.* Avoid storing the amp in damp or dusty rooms to spare jacks, switches and potentiometers. If you don't use the amp all the time, I recommend that you drape a covering over it to prevent the intrusion of dust. Even better, keep it in a transport cover or flight case.* Never use caustic or scouring detergents to clean the amp's housing, front or rear panels.Use a soft, damp cloth or sponge with diluted soapsuds or a standard brand of mild dishwashing liquid instead. Never use solvents they can corrode the amp's vinyl skin and dissolve the front and rear panel labels. Keep liquids well away from the amp, particularly the interior of the housing.* Make sure air can circulate at the rear and top of the amp to allow for adequate cooling, which increases component life.* Never operate the amp without an adequate load (a speaker, cabinet or suitable terminating resistor).* High ambient temperatures place an additional strain on diverse components; so if at all possible, avoid operating the amp at temperatures far higher than 30°C (86°F) for longer periods.Running the amp at mains voltages exceeding the nominal mains input voltage over longer periods can also shorten component life.* Replace tubes with selected tubes that satisfy ENGL selection criteria to forestall microphonic properties, undesirable noise and unbalanced power amp signals.Because power tubes' idle current (bias) must checked and possibly adjusted when replacing tubes, this is a job best left to experienced and authorized specialists.Technical DataRated power: approx. 30 watts at 8 or 16 ohms;Input sensitivity level Input, Clean channel: -20 dBInput sensitivity FX Return: -10 dB, approx. +10 dB max.;Output level FX Send, level range: -10 dB to approx. +5 dB peak;Tubes: V1: ECC 83 (12AX7) selected; V2, V3, V4, V5: EL 84 (6BQ5) matched set.Fuses:Mains fuse: 0.63 ATL (slow) for the 230 Volt model;1.25 ATL (slow) in the 100 and 120 Volt models.Power Tube Fuses (internal): 4 x 0.063 AM (63 mA medium blow)Important: Replace fuses only against same type and rating!Power Consumption: approx. 138 watts max.Dimensions: Head - E305 approx. 49.5 x 22 (24) x 25 cm; 19.5" x 8.7" x 9.8"; (W x H x D) Combo - E300 approx. 49.5 x 43 (45) x 25 cm; 19.5" x 17" x 9.8"; Weight: Head - E305 approx. 12 kg; 26.5 lbs; Combo - E300 approx. 18 kg; 39.7 lbs;Speaker in Combo E300: 12" Celestion;Tube replacement report:Replaced on: _ _ _ _ _ _ _ 20 _ _ _ Replaced by: _ _ _ _ _ _ _ _ _ _ _ _ _ _Replaced tubes V1: O V2: O V3: O V4: O V5: OReason: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _Troubleshooting* The amp does not power-up after you have switched the power on.The control lamp inside the power switch (15) does not light.-> Is the mains cord connected to the receptacle / live power source ?-> Is the power cable you are using intact ? Try another equal mains cable.-> Is the mains lead properly connected to the AC Power Inlet (16) at the amp ?-> Possibly the mains fuse (17) has blown, unplug the mains cord from the mains connectorand the receptacle and check the mains fuse.* The amp fails to respond when you try to control switching functions remotelyusing a footboard such as the Z-4 or a MIDI switcher such as the ENGL Z-11.-> Are the footpedals (or the switching loops) connected to the correspondingfootswitch jacks (18, 19, 20) ?-> Are the cords you are using stereo, intact, and wired properly ?(Refer to "Wiring of Principal Connectors" for pin assignments.)-> If you are using footswitches other than an ENGL Z-4 or Z-11, are the switches or relays inside the boards or switching loop systems off / on Single Pole Single Throw (SPST) switches? In other words, do these switches continuously connect to GND when you wish to activate the given function?If you're unsure about the answers to these questions, consult an authorized service centeror a professional specialist.* The amp is not providing an output signal / no sound is emanatingfrom the speaker.-> Is at least one speaker connected to the speaker outputs 8 ohms (24, 25) or 16 ohms (26) ?-> Is the power amp activated (Standby switch to ON) ?-> Are all cords (guitar, effect, and speaker) connected properly and are they functional ?-> Unplug connected effectors and see if the amp works fine without these peripheral devices.-> Are the Master, Lead Drive or Lead Volume knobs set to a value greater than 0 ?If any of these knobs is fully down, no signal is routed to the amp's outputs.-> You may be looking at a faulty tube or another defect. (the internal power tube fuses blown, etc.) In this case, be sure to take the preamp to an authorized, professional service center.* The speaker is emitting humming noises:-> Is there a connection (for example, via a shielded circuit, e.g. Line Out) between the ampand another device that is grounded via a power plug of its own?Two or more circuits sharing a common electrical ground line can cause audible hum.If low-frequency noise is emanating from your rig, be sure to consult a specialist.-> The amp and mains grounds are not connected properly or are altogetherdisconnected. Have an experienced specialist check this.-> Cords connected to the input or effect loops may not be shielded properly.Replace them to check if this is indeed the case.-> The amp or speaker cords may be picking up interference from powerfulmagnetic fields (for example, of nearby power transformers or electrical motors).Reposition the amp and connector cables.-> The amp or speaker cords may be picking up radio signals, for example,from activated mobile telephones or powerful local transmitting stations nearby.Switch off mobile phones while troubleshooting noise problems.CAUTION! Please read and heed the following:You'll find an ancillary pamphlet accompanying this owner's manual entitledInstructions for the Prevention of Fire, Electrical Shock and Injury.Be sure to read it before you plug in and power up the amp!1. Use a dual footswitch such as the ENGL Z-4, connecting it to the amp via a stereo cord equippedwith ¼" jack plugs. You can switch channels and Gain Boost via the dual footswitch connected to port 20, Mid Boost and M.V.B. via the dual footswitch connected to port 19, and FX Loop Off/On and Reverb Off/On via the dual footswitch connected to port 18.2. Use a MIDI switcher such as the ENGL Z-11, c onnecting it to the amp via three stereo cordsequipped with ¼" jack plugs. The buttons on the switcher can serve to control Clean/Lead, Gain Boost, Mid Boost, M.V.B., the FX Loop, and Reverb.You can also program all kinds of switching setups to the various MIDI program locations. Here's just one example: You could configure MIDI Preset #1 so that the Clean channel, Gain Boost, and Reverb are on, while Mid Boost, M.V.B., and the FX Loop are off. Then you could set MIDI Preset #2 up so that Lead channel, Mid Boost, and M.V.B. are on, while Gain Boost, the FX Loop, and Reverb are off.Whatever setups you decide to program, you can easily activate the desired configuration directly viaa MIDI board such as the ENGL Z-9, Z-12, or Z-15.This type of control option is extremely versatile; we recommend it highly if you intend to use the amp in conjunction with any MIDI system, including MIDI effects devices.Stereo1/4" jacktip: refer to*Tring: refer to *Rsleeve: Ground (Shield)Use a stereoplug only!Stereo1/4" plug*Rtip *TWiring of Principal Connectors: Footswitch (18, 19, 20)Your options for controlling the GigMaster 30 amp remotely:Technical specifications are subject to change without notice.ENGL Gerätebau GmbHInternet: Text, design, graphics and layout byHorst Langer, ENGL Amp DesignerFootswitch jack (20):*R: A switch connected to this terminal controlsGain Boost: off <--> on;*T: A switch connected to this terminal controlsChannel switching: Clean <--> Lead;Footswitch jack (18):*R: A switch connected to this terminal controlsReverb: off <--> on;*T: A switch connected to this terminal controlsFX Loop: off <--> on;Footswitch jack (19):*R: A switch connected to this terminal controlsM.V.B. off <--> on (low / high level);*T: A switch connected to this terminal controlsMid boost: off <--> on;。

Thus the settingprocedure has to be repeated.Following this setting procedure, the sensor functions in the LIGHTmode with proximity fibres and in the DARK mode with through beamfibres. To set the sensor in the DARK mode for proximity or LIGHTmode for through beam, invert the sequence given above.The operative DARK/LIGHT mode is automatically selected by thesensor when is used as contrast sensor.‘OR’ function by means of parallel output connectionThe 1 and 2 outputs can be connected together in parallel, obtainingan ‘OR’ function; this means that the common output is activatedeven if just one of the two fibres has detected the object.DECLARATION OF CONFORMITYWe DATALOGIC AUTOMATION declare under our sole responsibilitythat these products are conform to the 2004/108/CE and successiveamendments.WARRANTYDATALOGIC AUTOMATION warrants its products to be free fromdefects.DATALOGIC AUTOMATION will repair or replace, free of charge, anyproduct found to be defective during the warranty period of 36 monthsfrom the manufacturing date.This warranty does not cover damage or liability deriving from theimproper application of DATALOGIC AUTOMATION products.DATALOGIC AUTOMATIONVia Lavino 265 - 40050 Monte S.Pietro - Bologna – ItalyTel: +39 051 6765611 - Fax: +39 051 6759324e-mail:********************************Datalogic and the Datalogic logo are registered trademarks of DatalogicS.p.A. in many countries, including the U.S.A. and the E.U.826000992Rev.C© Copyright Datalogic 2008-2010。

光纤放大器的常规调节方法
光纤放大器的常规调节方法使用漫反射光纤，状态在1.将MODE 拨到2.通电后，将光纤对到检测物体，红光OUT亮，将旋钮左旋到OUT灯灭，再将旋钮向右以1/4圈的速度旋转到OUT红灯亮，调整完毕。
如需反向动作，做切换使用对射光纤，状态在1.将MODE拨到2.通电后，将光纤安装好，没有检测物体的情况下，如红灯亮，将旋钮左转到OUT灯灭，再将旋钮向右以1/4圈的速度旋转到OUT红灯亮，调整完毕。
将检测物体放入光纤之间，OUT灯灭。
如需反向动作，做切换光纤放大器工作原理及其在无线光通信的应用0 引言无线光通信是以激光作为信息载体，是一种不需要任何有线信道作为传输媒介的通信方式。
与微波通信相比，无线光通信所使用的激光频率高，方向性强(保密性好)，可用的频谱宽，无需申请频率使用许可；与光纤通信相比，无线光通信造价低，施工简便、迅速。
它结合了光纤通信和微波通信的优势，已成为一种新兴的宽带无线接人方式，受到了人们的广泛关注。
但是，恶劣的天气情况，会对无线光通信系统的传播信号产生衰耗作用。
空气中的散射粒子，会使光线在空问、时间和角度上产生不同程度的偏差。
大气中的粒子还可能吸收激光的能量，使信号的功率衰减，在无线光通信系统中光纤通信系统低损耗的传播路径已不复存在。
大气环境多变的客观性无法改变，要获得更好更快的传输效果，对在大气信道传输的光信号就提出了更高的要求，一般地，采用大功率的光信号可以得到更好的传输效果。
随着光纤放大器(EDFA)的迅速发展，稳定可靠的大功率光源将在各种应用中满足无线光通信的要求。
1 EDFA的原理及结构掺铒光纤放大器(EDFA)具有增益高、噪声低、频带宽、输出功率高、连接损耗低和偏振不敏感等优点，直接对光信号进行放大，无需转换成电信号，能够保证光信号在最小失真情况下得到稳定的功率放大。
1．1 EDFA的原理EDFA的泵浦过程需要使用三能级系统，如图1所示。
在掺铒光纤中注入足够强的泵浦光，就可以将大部分处于基态的Er3+离子抽运到激发态，处于激发态的Er3+离子又迅速无辐射地转移到亚稳态。

开关频率最大1K Hz，反应时间：250us或更少。
延时时间，以保证当产品检测高速移动的小尺寸物体时，产品的输出信号能够被设备的
控制系统捕捉到。较长的延时时间也可以用于一些特殊的应用。
7 功能设置
一、学习功能：
在工作状态下，压下学习键 换为开关阀值。 图例：
TEACH ，时间超过2秒钟，传感器会自动把当前值记录下并替
+
二、阀值设置功能：
在工作状态下，压下设置键 INC 或 DEC ，阀值会对应加减，按 按 DEC 一次阀值减1。一直按住按键阀值会连续加减。
当产品输出出现短路或过载时，产品控制系统会切断输出。产品控制系统会一直监控
输入的光信号和输出负载的变化，直到两者符合相关条件才退出短路或过载保护状态。
