均衡器各功能键的作用及中英文对照

均衡器各功能键的作用及中英文对照

频率均衡器在歌舞厅和厅堂扩声中应用很多,其本要作用有:1.校正音响设备产生的频率畸变,能补偿各种节目信号中欠缺的频率成分,又能抑制过重的频率成分;2.校正室内声学共振特性产生的频率畸变,弥补建筑声学的结构缺陷;3.抑制声反馈,改善厅堂扩声的质量;4.修饰或美化音色,提高音质和音响效果。

例如,在厅堂扩声或歌舞厅音响系统安装完毕后,由于厅堂声学共振而使扩声系统(包括传声器、放大器、音箱、房间的传输特性)的频率特性曲线起伏很大,这时就可借助频率均衡器房间均衡器),通过提升(或衰减)由于厅堂对某些频率而造成的谷点(或峰点),使总响应特性趋于平坦,这就是所谓镜像均衡。

对于存在声反馈的扩声系统,在均衡处理之前,要使扩声系统稳定,最大增益只能开大到使频响曲线中最大峰点接近自激之处。

此时,除最大峰点附近很窄频段外,大部分频段内扩声增益都很低,常常不能足使用要求。

借助频率均衡器处理后,大的峰点被消除,频率特性变均匀了,使所有频率点的扩声增益都有相当大的提高。

至于利用频率均衡器来修饰音色,提高音质是大家所共知的。

三、均衡器的主要技术指标(一)频率点数(段数)均衡器的中心频率设置台前所述,是有一定规律的,例如倍频程1/2倍频程和1/3倍频程等。

通常,频率点数越多,其频带宽度越窄,(即Q值越高)。

(二)均衡量亦即控制范围,它是指均衡器对中心频率所对应信号的最大提升提升或最大衰减量,常用分贝表示。

其规格有±6dB、±12dB、±15dB、±18dB等。

数值越大,表示控制能力越强。

图1-2-1图示均衡器的控制曲线(三)谐波失真度通常要求谐波失真应不大于0.1%。

(四)等效输入噪声级这是与信噪比相对应的指标、其值越小,信噪比越好。

通常要求等效输入噪声不大于)-90dB。

(五)对于参量均衡器还有Q值和中心频率调整范围Q值又称品质因数。

Q值越高,均衡器提升或衰减曲线越尖锐,带宽也越窄;反之,Q值越低,带宽越宽。

LOREX Live Connect LW2031系列无线Skype家庭监控评测说明书

LOREX Live Connect Wireless Skype Home Surveillance ReviewOctober 25, 2011The LOREX Technology Live Connect LW2031 Series is a cool Skype-powered home surveillance system sporting night vision (via IR LEDs) and full color H.264 video. It can be used both for home surveillance, but also as a baby monitor due to its night vision and its portable handheld monitor sporting a color 2.4" LCD. It seemed like an interesting Skype product so I had LOREX send me a LW2031 to review.InstallationInstalling this was pretty straightforward. Two of the three devices - camera & handheld monitor use mini-USB power adapters, which are included. The gateway device uses a 5V AC adapter, which is also included. They ship the rechargeable batteries in the camera and the handheld monitor partially charged, so I only needed to hook up power to the gateway initially. I also connected the included Ethernet cable. I powered on the handheld device and in seconds I was able to see the video feed from the camera, which ships already "paired" to the gateway. You can pair up to 4 cameras. Local viewing on handheld monitor supports up to 4 cameras in auto-sequence mode (one camera at a time) or selectable single camera viewing. In just two minutes I had everything out of the box and working.Hooking up SkypeThe only thing that might trip up potential buyers is that they need to have two Skype usernames. One personal one and an additional Skype username to assign to the LOREX Live Connect system. Fortunately, their instructions are very good and the Getting Started single sheet spells this out very clearly. The next part of the Getting Started guide is to launch to the web interface of the gateway. It's actually pretty simple since it leverage UPnP. All you have to do it click Start, Computer, Network, thenunder Other Devices I was able to see "LOREX Gateway". Then you simple double-click which opens the IP address into your default browser.LOREX Web Admin InterfaceThe web interface asked for a timezone and then asked if I had a Skype name. I already have test Skype accounts, but I was curious what the "user experience" was for users without multiple Skype usernames, so I selected the option for no Skype username. It then allowed me to register a new Skype username without having to leave this interface, go to and register there. Definitely a nice touch to make it as easy as possible.After registering the new Skype username, I logged into Skype using these new credentials. I then added a new contact - my primary/personal Skype username. I logged out, then logged in with my primary Skype username and accepted the contact request. Now I was ready to call the Lorex Live Connect over Skype!I made a call and the Lorex Live Connect gateway automatically answered the call and began transmitting video in about 15 seconds. This was really my own complaint with the product - that it took 15s before video began. Fortunately, audio is near instantaneous.Lights on vs. Lights offThe video quality was pretty good. I captured a video (using iPhone 4s) of the video call, including some video of the handheld monitor and uploaded it to YouTube, which you can watch here:I should point out that the YouTube video I took above was taken with my office lights off, and my window shades closed since I was trying to duplicate "baby monitor" type conditions - or at least very low-light conditions. Though it wasn't pitch dark, my office was pretty dark, so I was pretty amazed thatin low-light conditions and even with the IR sensors not kicked in (not quite dark enough), that the video quality was pretty good. You obviously get more "noise" in a video when taken in a darkened room, so to be fair and to get an accurate representation of the quality of the video in a brightened room I also snapped this screenshot with my office lights on:As you can see, the quality is pretty good. You can even make out my greying sideburns. Oh and the Monster Pump Creatine mix on my shelf. I liked that the camera was very rotational allowing you to get just the right angle. The back of the base has a hole allowing you to wall-mount the camera. The camera microphone was quite sensitive and easily picks up the slightest sound even 20 feet away, making it very useful as a baby monitor or to covertly listen in on conversations!The handheld monitor, which features a 2.4" color LCD is a handy little device for when you're home and want to monitor a room or area, such as a playpen or crib. It had pretty good range in my testing and they claim 150 foot range. The color quality was pretty decent and the frame rate was pretty good as well. Here's a sample photo of it:Interestingly, the handheld monitor sports a microSD memory slot on the side and the unit ships with a 1GB microSD memory card, as well as a microSD adapter for connecting to your PC. From the handheld monitor you can kick off an impromptu video recording by pressing the camera icon button for 5s. The handheld monitor records 320x240 video but it doesn't support audio recording. Though if you really insist on recording audio, there are plenty of Skype add-ons that support both video and audio recording to your PC.Because the system leverages Skype, you can use your smartphone, tablet (i.e. iPad), PC, or Mac to view the video and listen to the audio. Initially my new iPhone 4S running Skype had problems when calling the LOREX Live Connect. The call connected, but then after about 15s it tried to initialize video and then it just dropped the call. The audio worked for the first 15s or so before the call dropped. I rebooted my 4S and tried again and then it worked. Damn iPhone! I also tried it on an iPad 2 and it worked fine on the first try.Features & SpecificationsVideo camera:• Image Sensor: CMOS• Image Resolution: 640 x 480 up to 20fps• Automatic night-vision up to 22ft• Minimum Illuminat ion: 0 Lux (IR on)• View Angle: H: 64°, V: 48°• Built-in rechargeable lithium battery for portable use (4 hrs battery life)• Power adapter included for continuous non-portable use.• Secure, private Digital Wireless video & audio• Built-in microphone for listen-in audioHandheld monitor:• Color 2.4" LCD• 640x480 resolution• Compact design with rechargeable lithium battery for trueportability• Snap, store and share pictures and video with microSD recording• Expandable up to 4 cameras• Digital Wi reless range up to 150ft indoors. Actual range may vary depending on obstructions.Internet Gateway:• Remote viewing via Skype compatible devices (PC, Mac,iPhone 4/3GS, iPad/iPad 2)• H.264 video compression for efficient internet streamingConclusionThe LIVE CONNECT LW2031 Series is an certainly an easy-to-use portable home monitor and surveillance system. It will retail for $299.99, which is a bit of a premium. Just for price comparison, I searched Amazon for baby monitor with night vision and the products range from $80 to over $269, however even the most expensive one doesn't support Skype. So when you combine the portable handheld monitor for local monitoring, the night vision feature, support for four cameras, and the Skype capabilities, this certainly makes for a worthy home surveillance choice.very rotational - xyzLights vs. Lights offThe YouTube video I took was taken with the lights off, and my window shades closed.

This is accomplished by including components L1 and C4 on the PC board (see the Modifying the EV Kit section for details.The MAX2031 EV kit is fully assembled and factory tested.Follow the instructions in the Connections and Setup sec-tion for proper device evaluation.Test Equipment RequiredThis section lists the recommended test equipment to verify the operation of the MAX2031. It is intended as a guide only, and substitutions may be possible.•One DC supply capable of delivering +5.0V and150mA •Three RF signal generators capable of delivering 10dBm of output power in the 100MHz to 1GHz fre-quency range (i.e., HP 8648)•One RF spectrum analyzer with a 100kHz to 3GHz minimum frequency range (HP 8561E)•One RF power meter (HP 437B)•One power sensor (HP 8482A)Connections and SetupThis section provides a step-by-step guide to testing the basic functionality of the EV kit. As a general pre-caution to prevent damaging the outputs by driving high-VSWR loads, do not turn on DC power or RF signal generators until all connections are made.This procedure is specific to operation in the cellular band high-side-injected LO for upconverter operation to an 810MHz RF signal. Choose the test frequency based on the particular system ’s frequency plan, and adjust the following procedure accordingly. See Figure 1 for the mixer test setup diagram.1)Calibrate the power meter. For safety margin, use apower sensor rated to at least +20dBm, or use padding to protect the power head as necessary.2)Connect 3dB pads to DUT ends of each of the twoRF signal generators ’ SMA cables. This paddingimproves VSWR, and reduces the errors due to mis-match.3)Use the power meter to set the signal generatorsaccording to the following:•IF signal source: 0dBm into DUT at 160MHz (approximately 3dBm before the 3dB pad)•LO1 signal source: 0dBm into DUT at 970MHz (approximately 3dBm before the 3dB pad)•LO2 signal source: 0dBm into DUT at 969MHz (approximately 3dBm before the 3dB pad)4)Disable the signal generator outputs.5)Connect the IF source (with pad) to the IF port.6)Connect the LO1 and LO2 signal sources to the EVkit LO inputs.7)Measure loss in the 3dB pad and cable that will beconnected to the RF port. Losses are frequency-dependent, so test this at 810MHz (the RF frequen-cy). Use this loss as an offset in all output power/gain calculations.8)Connect this 3dB pad to the EV kit ’s RF port con-nector and connect a cable from the pad to the spectrum analyzer.9)Set DC supply to +5.0V, and set a current limit ofaround 150mA if possible. Disable the output voltage and connect the supply to the EV kit (through an ammeter, if desired). Enable the supply. Readjust the supply to get +5.0V at the EV kit. There will be a volt-age drop across the ammeter when the mixer is drawing current.10)Select LO1 by connecting LOSEL (TP3) to GND.11)Enable the LO and the RF sources.The procedure for downconverter operation from RF to the IF band is similar to the steps listed above. For downconverter operation, connect the RF signal source (with pad) to the RF port and connect a 3dB pad and cable to the IF port from the spectrum analyzer.MAX2031 Evaluation Kit 2_______________________________________________________________________________________Testing the Mixer Adjust the center and span of the spectrum analyzer to observe the RF output tone at 810MHz for upconverter operation. The level should be about -10dBm (7dB con-version loss, 3dB pad loss). The spectrum analyzer’s absolute magnitude accuracy is typically no better than ±1dB.Disconnect the GND connection to LOSEL. It will be pulled high by a pullup resistor on the board, selecting LO2. Observe that the 809MHz signal increases while the 810MHz decreases.Reconfigure the test setup using a combiner or hybrid to sum two of the frequency sources to do a two-tone IP3 measurement if desired. Terminate the unused LO input in 50Ω.Detailed Description The MAX2031 is a high-linearity up/downconverter inte-grated with RF and LO baluns, an LO buffer, and an SPDT LO input select switch. The EV kit circuit uses the MAX2031 and consists mostly of supply-decoupling capacitors, DC-blocking capacitors, a current-setting resistor, and an IF balun. The MAX2031 EV kit circuit allows for thorough analysis and a simple design-in.Supply-Decoupling Capacitors C2, C7, C8, and C11 are 82pF supply-decoupling capacitors used to filter high-frequency noise. C3, C6, and C9 are larger 0.01µF capacitors used for filtering lower frequency noise on the supply.DC-Blocking Capacitors The MAX2031 has internal baluns at the RF and LO inputs. These inputs have almost 0Ωresistance at DC, so DC-blocking capacitors C1, C10, and C12 are used to prevent any external bias from being shunted directly to ground.LO Bias The bias current for the integrated LO buffer is set with resistor R1 (523Ω±1%). Increasing the value of R1 can reduce the DC current of the device but the device would operate at reduced performance levels (see the Modifying the EV Kit section).TAP Network The TAP pin for the internal balun is grounded.IF±The MAX2031 mixer has a DC to 250MHz IF frequency range. Note that these differential ports are ideal for providing enhanced IIP2 performance. Single-ended IF applications require a 1:1 balun to transform the 50Ωdifferential IF impedance to 50Ωsingle-ended. After thebalun, the IF return loss is better than 15dB. The differ-ential IF is used as an input port for upconverter opera-tion. The user can use a differential IF amplifier follow-ing the mixer but a DC block is required on both IFpins.Tuning Networks The performance of the MAX2031 is enhanced with theaddition of external tuning networks. Capacitor C4 andinductor L1 form a bandpass filter network that enhancesthe linearity performance when the mixer is used toupconvert an IF port signal to the RF port. This network isconstructed on the kit and limits the usable RF band-width to approximately 750MHz to 850MHz (refer to theMAX2031 data sheet). This network can be tuned toaccommodate other RF bands if desired.Capacitor C5 is used to improve the linearity perfor-mance of the MAX2031 when the mixer is used todownconvert an RF port signal to the IF port. The valueof this cap could change slightly depending on the RFand LO frequencies.Capacitor C5 is not required for upconverter operationand the C4/L1 network is not required for downconverteroperation.LOSEL The EV kit includes a 47kΩpullup resistor (R2) for easyselection of the LO port. Providing a ground at TP3selects LO1, and leaving TP3 open selects LO2. Todrive TP3 from an external source, follow the limitscalled out in the MAX2031 device data sheet. Logicvoltages should not be applied to LOSEL without the+5V supply voltage. Doing so can cause the on-chipESD diodes to conduct and could damage the device.Layout Considerations The MAX2031 evaluation board can be a guide for boardlayout. Pay close attention to thermal design and closeplacement of components to the IC. The MAX2031 pack-age exposed paddle (EP) conducts heat from the deviceand provides a low-impedance electrical connection tothe ground plane. The EP must be attached to the PCboard ground plane with a low thermal and electricalimpedance contact. Ideally, this is achieved by solderingthe backside of the package directly to a top metalground plane on the PC board. Alternatively, the EP canbe connected to an internal or bottom-side ground planeusing an array of plated vias directly below the EP. TheMAX2031 EV kit uses nine evenly spaced, 0.016in-diam-eter, plated through holes to connect the EP to the lowerground planes.Depending on the ground plane spacing, large sur-face-mount pads in the IF path may need to have theEvaluates: MAX2031 MAX2031 Evaluation Kit_______________________________________________________________________________________3E v a l u a t e s : M A X 2031ground plane relieved under them to reduce parasitic shunt capacitance.Modifying the EV KitThe standard kit is configured as an upconverter and includes the band-limiting C4/L1 network. This network is tuned to produce the best results from 750MHz to 850MHz. This network can be tuned to the desired RF band by changing the values of L and C.If the kit is to be used as a downconverter, then C4 and L1 can be removed. Capacitor C5 should be installed to improve the downconverter linearity performance.This capacitor might need to be tuned slightly depend-ing on the RF and LO frequency bands of interest.The DC current of the device can be reduced if reduced performance is acceptable. Reducing the current is accomplished by increasing the value of R1. Doubling the value of R1 cuts the DC current approximately in half.Approximately 10% of the overall IC current is used for housekeeping (R1 set at 523Ω) and cannot be reduced.MAX2031 Evaluation Kit 4_______________________________________________________________________________________Figure 1.

Q: 最小测量功率是多少? A: 数字驻波表测量过程与指针表有 所差别,指针表是通过绘制驻波读数刻
度的方法来换算的,因此需要有一个最
小测量功率以驱动表头指针达到满度位
置,才能利用刻度换算驻波读数,数字
表是同时采样正反向信号,然后自动计
算驻波读数的,没有最小测量功率的限
制,只是驻波很小时,反射信号更小,

用大一些的功率测量比小些的功率测量
可以更准确一些,比如有 0.1W 的功率就 可以读数了,但是用 1W 的功率测量会 更好。
Q: 环境温度对测量发射功率有影响 吗?
A:环境温度的较大差别对功率的测 量是有影响的,仪表校准是在 20℃左右 的室温校准的,使用温度过高,测量功
率会偏大,温度过低会偏小,对驻波测

★ 仪表内部,传感器部分的磁环线圈、 电位器等元件,不要随便触动,如需校准, 请参考校准方法说明
★ 测量中应根据实际测量环境,客观 的分析测量结果。高频电磁波是以电场和 磁场的波动形式传递能量的,这与一般电 工中,电能在导体内传递使不同的,会受 到多种因素的影响,就测量原理本身而 言,当被测负载(包括天线)的驻波很大 时,功率的测量误差也会很大,这时需要 首先将负载匹配好后,再测量的功率才有 实际意义,一般要负载驻波<1.2,当然对 于 HAM 应用,天线驻波<1.5 就可以了。

常见问题: Q: 按下大红点后不能开机,或开机
背光闪一下就关机了? A: 这是电池电压过低,电量耗尽了,
功率计/驻波表的用途: 通过式功率计/驻波表,它的原理是
在传输线一侧放置了一个耦合探头,与发 射机的工作波长相比,功率计传感器的电 长度几乎可以忽略不计。所以只要将通过 式功率计置于发射系统的某个截面,那么 得出的结果是这个截面的正向和反向功 率(SWR)。
对于无线电运营、制造和使用,通过 式功率测量法是很有意义的。在一个典型 的发射系统中(见下图),将通过式功率 计置于不同的截面将会得到不同的测试 结果:
量影响很小。
Q:数字驻波表可以测量馈线的衰减 吗?
A:数字驻波表配合电台和假负载可 以测量馈线的衰减。将假负载直接接到
驻波表的 ANT 端,将 TX 端连到电台发 射端,按下发射键,记下正向功率读数
a1,然后在电台和驻波表之间接入要测 的电缆,按下发射键,记下正向功率读
数 a2,然后量一下被测电缆的长度 L 米, 就可以计算测量频率下该电缆的衰减:
背光开关: 在夜间或光线较弱的情况下,按下红
色按钮并保持约 1 秒,即可打开背光,同 样按下红色按钮并保持约 1 秒,即可关闭 背光。
关闭电源: 当没有发射信号时间持续超过 8 分钟
后,电源自动关闭,也可以按下红色按钮 并保持约 2 秒以上,抬起后则立即关闭。
注意事项: ★ 由于很省电,电池可以用很长时间,
6.5V,即使短暂超过,也可能造成内部电 子器件的损坏,切记!

位置②——可以检查发射系统在某 个位置的匹配情况,这是设备维护所关心 的。
用二台通过式功率计可以十分准确 的测出一个无源器件的插入损耗,其精度 和网络分析仪的测试结果相当(如图 A、 B)。这种测量方法的基本原理是替代法。 即先将二台功率计用一只精密的射频转 接器(如 N-JJ)直接连接,再用被测器 件替代射频转接器,分别读出 4 个功率读 数从而计算出被测器件的准确插入损耗 值。用这种方法可以准确的测出从发射机 输出端到天线输入端的全部插入损耗,这 对于天馈系统的维护是有益的。虽然用网 络分析仪也可以单端测量长电缆的插入 损耗,但是网络分析仪必须在同一种介质 下测量,而且要准确设定电缆的相速度, 否则会产生附加的测试误差;而用功率计 法就不需要知道这些参数,它只是把整个 系统(包括跳线、主馈线,避雷器,定向 耦合器等)一并当作一个二端口网络来对 待。
