It is recommended to complete every step before reverting to a normal user mode.1. Install ADC Analyzer from the CD provided in the FIFOevaluation kit or download the latest version on the Web. For the latest updates to the software, check the Analog Devices website at /hsc-FIFO . 2. Connect the FIFO evaluation board to the ADC evaluationboard. If an adapter is required, insert the adapter between the ADC evaluation board and the FIFO board. If using the HSC-ADC-EV ALB-SC model, connect the evaluation board to the bottom two rows of the 120-pin connector, closest to the installed IDT FIFO chip. If using an ADC with a SPI interface, remove the two 4-pin corner keys so that the third row can be connected. 3. Connect the provided USB cable to the FIFO evaluationboard and to an available USB port on the computer. 4. Refer to Table 5 for any jumper changes. Most evaluationboards can be used with the default settings. 5. After verification, connect the appropriate power suppliesto the ADC evaluation boards. The FIFO evaluation board is supplied with a wall mount switching power supply that provides a 6 V , 2 A maximum output. Connect the supply end to the rated 100 ac to 240 ac wall outlet at 47 Hz to 63 Hz. The other end is a 2.1 mm inner diameter jack that connects to the PCB at J301. Refer to the instructions included in the ADC data sheet for more information about the ADC evaluation board’s power supply and other requirements. 6. Once the cable is connected to both the computer and theFIFO board, and power is supplied, the USB drivers start to install. To complete the total installation of the FIFO drivers, you need to complete the new hardware sequence two times. The first Found New Hardware Wizard opens with the text message This wizard helps you install software for…Pre-FIFO 4.1. Click the recommended install, and go to the next screen. A hardware installation warning window should then be displayed. Click Continue Anyway . The next window that opens should finish the Pre-FIFO 4.1 installation. Click Finish . Y our computer should go through a second Found New Hardware Wizard , and the text message, This wizard helps you install software for…Analog Devices FIFO 4.1, should be displayed. Continue as you did in the previous installation and click Continue Anyway . Then click Finish on the next two windows. This completes the installation. 7. (Optional) Verify in the device manager that AnalogDevices, FIFO4.1 is listed under the USB hardware. 8. Apply power to the evaluation board and check the voltagelevels at the board level. 9. Connect the appropriate analog input (which should befiltered with a band-pass filter) and low jitter clock signal. Make sure the evaluation boards are powered on before connecting the analog input and clock. 10. Start ADC Analyzer.11. Choose an existing configuration file for the ADCevaluation board or create one. 12. Click Time Data in ADC Analyzer (left-most button underthe menus). A reconstruction of the analog input isdisplayed. If the expected signal does not appear, or if there is only a flat red line, refer to the ADC Analyzer data sheet at /hsc-FIFO for more information.HSC-ADC-EVALB-SC/HSC-ADC-EVALB-DCRev. 0 | Page 4 of 28VIRTUAL EVALUATION BOARD EASY START WITH ADIsimADCREQUIREMENTSRequirements include • Completed installation of ADC Analyzer, Version 4.5.17 or later.•ADIsimADC product model files for the desired converter. Models are not installed with the software, but they can be downloaded from the ADIsimADC Virtual Evaluation Board website at no charge.No hardware is required. However, if you wish to compareresults of a real evaluation board and the model, you can switch easily between the two, as outlined in the following Easy Start Steps section.EASY START STEPS1. To get ADC model files, go to /ADIsimADCfor the product of interest. Download the product ofinterest to a local drive. The default location is c:\program files\adc_analyzer\models. 2.

The evaluation kit is based around the IDT72V283 FIFO chip from Integrated Device Technology, Inc (IDT). The system can acquire digital data at speeds up to 133 MSPS and data record lengths up to 32 kB using the HSC-ADC-EV ALB-SC FIFO evaluation kit. The HSC-ADC-EVALB-DC, which has two FIFO chips, is available to evaluate multichannel ADCs or demultiplexed data from ADCs sampling faster than 133 MSPS. A USB 2.0 microcontroller communicating with ADC Analyzer allows for easy interfacing to newer computers using the USB 2.0 (USB 1.1-compatible) interface.The process of filling the FIFO chip or chips and reading the data back requires several steps. First, ADC Analyzer initiates the FIFO chip fill process. The FIFO chips are reset, using a master reset signal (MRS). The USB microcontroller is then suspended, which turns off the USB oscillator and ensures that it does not add noise to the ADC input. After the FIFO chips completely fill, the full flags from the FIFO chips send a signal to the USB microcontroller to wake up the microcontroller from suspend. ADC Analyzer waits for approximately 30 ms and then begins the readback process.During the readback process, the acquisition of data from FIFO 1 (U201) or FIFO 2 (U101) is controlled via Signal OEA and Signal OEB. Because the data outputs of both FIFO chips drive the same 16-bit data bus, the USB microcontrollercontrols the OEA and OEB signals to read data from the correct FIFO chip. From an application standpoint, ADC Analyzer sends commands to the USB microcontroller to initiate a read from the correct FIFO chip, or from both FIFO chips in dual or demultiplexed mode.CLOCKING DESCRIPTIONEach channel of the buffer memory requires a clock signal to capture data. These clock signals are normally provided by the ADC evaluation board and are passed along with the data through Connector J104 (Pin 37 for both Channel A and Channel B). If only a single clock is passed for both channels, they can be connected together by Jumper J303.Jumpers J304 and J305 at the output of the LVDS receiver allow the output clock to be inverted by the LVDS receiver. By default, the clock outputs are inverted by the LVDS receiver.The single-ended clock signal from each data channel is buffered and converted to a differential CMOS signal by two gates of a low voltage differential signal (LVDS) receiver, U301. This allows the clock source for each channel to be CMOS, TTL, or ECL. The clock signals are ac-coupled by 0.1 μF capacitors.Potentiometer R312 and Potentiometer R315 allow for fine tuning the threshold of the LVDS gates. In applications where fine-tuning the threshold is critical, these potentiometers can be replaced with a higher resistance value to increase theadjustment range. Resistors R301, R302, R303, R304, R311, R313, R314, and R316 set the static input to each of the differential gates to a dc voltage of approximately 1.5 V . At assembly, Solder Jumper J310 to Solder Jumper J313 are set to bypass the potentiometer. For fine adjustment using the pot, the solder jumpers must be removed, and R312 and R315 must be populated.U302, an XOR gate array, is included in the design to let users add gate delays to the FIFO memory chip clock paths. They are not required under normal conditions and are bypassed at assembly by Jumper J314 and Jumper J315. Jumper J306 and Jumper J307 allow the clock signals to be inverted through an XOR gate. In the default setting, the clocks are not inverted by the XOR gate.The clock paths described above determine the WRT_CLK1 and WRT_CLK2 signals at each FIFO memory chip (U101 and U201). The timing options above should let you choose a clock signal that meets the setup and hold time requirements to capture valid data.A clock generator can be applied directly to S1 and/or S3. This clock generator should be the same unit that provides the clock for the ADC. These clock paths are ac-coupled, so that a sine wave generator can be used. DC bias can be adjusted by R301/R302 and R303/R304.The DS90LV048A differential line receiver is used to square the clock signal levels applied externally to the FIFO evaluation board. The output of this clock receiver can either directly drive the write clock of the IDT72V283 FIFO(s), or first pass through the XOR gate timing circuitry described above.SPI DESCRIPTIONThe Cypress IC (U502) supports the HSC SPI standard to allow programming of ADCs that have SPI-accessible register maps. U102 is a buffer that drives the 4-wire SPI (SCLK, SDI, SDO, CSB 1) through the 120-pin connector (J104) on the third or top row. J502 is an auxiliary SPI connector to monitor the SPI signals connected directly to the Cypress IC. For more information on this and other functions, consult the user manual titled Interfacing to High Speed ADCs via SPI at /hsc-FIFO .1Note that CSB1 is the default CSB line used.HSC-ADC-EVALB-SC/HSC-ADC-EVALB-DCRev. 0 | Page 10 of 28The SPI interface designed on the Cypress IC can communicate with up to five different SPI-enabled devices. The CLK and data lines are common to all SPI devices. The correct device ischosen to communicate by using one of the five active low chip select pins. This functionality is controlled by selecting a SPI channel in the software.CLOCKING WITH INTERLEAVED DATAADCs with very high data rates can exceed the capability of a single buffer memory channel (~133 MSPS). These converters often demultiplex the data into two channels to reduce the rate required to capture the data. In these applications, ADC Analyzer must interleave the data from both channels to process it as a single channel. The user can configure the software to process the first sample from Channel A, the second from Channel B, and so on, or vice versa. The synchronization circuit included in the buffer memory forces a small delay between the write enable signals (WENA and WENB) to the FIFO memory chips (Pin 1, U101, and U201), ensuring that the data is captured in one FIFO before the other. Jumper J401 and Jumper J402 determine which FIFO receives WENA and which FIFO receives WENB.CONNECTING TO THE HSC-ADC-FPGA-4/-8ADCs that have serial LVDS outputs require another board that is connected between the ADC evaluation board and the FIFO data capture card. This board converts the serial data into parallel CMOS so that the FIFO data capture card can accept the data. For more detailed information on this board, refer to the HSC-ADC-FPGA datasheet at /hsc-FIFO . CONNECTING TO THE DEMUX BRDADCs that have parallel LVDS outputs require another board that is connected between the ADC evaluation board and the FIFO data capture card. This board converts parallel LVDS to parallel CMOS, using both channels of the FIFO data capture card. For more detailed information on this board, send an email to highspeed.converters@UPGRADING FIFO MEMORYThe FIFO evaluation board includes one or two 32 kB FIFOs that are capable of 133 MHz clock signals, depending on the model number.

NI-9234说明书

Sound and Vibration Data AcquisitionOverviewNI 9233 and 9234 are 4-channel dynamic signal acquisition (DSA)modules for making high-accuracy measurements from IEPE sensors.These C Series analog input modules deliver 102 dB of dynamic range and incorporate IEPE (2 mA constant current) signal conditioning for accelerometers and microphones. The four input channels simultaneously acquire at rates from 2 to 50 kHz or, with the NI 9234, up to 51.2 kS/s.In addition, the modules include built-in antialiasing filters that automatically adjust to your sampling rate. NI 9233/9234 modules are ideal for a wide variety of mobile/portable applications such as industrial machine condition monitoring and in-vehicle noise, vibration,and harshness testing.HardwareEach simultaneous signal is buffered, analog prefiltered, and sampled by a 24-bit delta-sigma analog-to-digital converter (ADC) that performs digital filtering with a cutoff frequency that automatically adjusts to yourdata rate. NI 9233/9234 modules feature a voltage range of ±5 V and a dynamic range of more than 100 dB. In addition, the modules include thecapability to read and write to transducer electronic data sheet (TEDS)Class 1 smart sensors. NI 9233/9234 modules provide ±30 V of overvoltage protection (with respect to chassis ground) for IEPE sensor connections.The NI 9234 has three software-selectable modes of measurement operation: IEPE-on with AC coupling, IEPE-off with AC coupling, and IEPE-off with DC coupling. IEPE excitation and AC coupling are not software-selectable and are always enabled for the NI 9233.NI 9233/9234 modules use a method of A/D conversion known as delta-sigma modulation. If, for example, the data rate is 25 kS/s, then each ADC actually samples its input signal at 3.2 MS/s (128 times the data rate) and produces samples that are applied to a digital filter.This filter then expands the data to 24 bits, rejects signal components greater than 12.5 kHz (the Nyquist frequency), and digitally resamples the data at the chosen data rate of 25 kS/s. This combination of analog and digital filtering provides an accurate representation of desirable signals while rejecting out-of-band signals. The built-in antialiasing filters automatically adjust themselves to discriminate between signals based on the frequency range, or bandwidth, of the signal.•24-bit resolution•102 dB dynamic range•4 simultaneous analog inputs •±5 V input range •Antialiasing filters •TEDS read/writeRecommended Software•LabVIEW•Sound and Vibration Toolkit•Sound and Vibration Measurement SuiteSupported Hardware Platforms•NI CompactDAQ •CompactRIO•Hi-Speed USB carrier •Wi-Fi/Ethernet carrierNI 9233, NI 9234NEW!Analysis Capabilities Power spectra Zoom FFTsFractional-octave analysis Vibration level measurementsWi-Fi/Ethernet Platform NEW!NI Wi-Fi data acquisition (DAQ) devices combine IEEE 802.11 wireless or Ethernet communication; direct sensor connectivity; and the flexibility of NI LabVIEW software for remote monitoring of electrical, physical, mechanical,and acoustical signals.

Communication to the USB carrier is over Hi-Speed USB, guaranteeing data throughput.NI CompactDAQ PlatformNI CompactDAQ delivers the simplicity of USB to sensor and electrical measurements on the benchtop, in the field, and on the production line. By combining the ease of use and low cost of a data logger with the performance and flexibility of modular instrumentation, NI CompactDAQ offers fast, accurate measurements in a small, simple, and affordable system. Flexible software options make it easy to use NI CompactDAQ to log data for simple experiments or to develop a fully automated test or control system. The modular design can measure up to 256 channels of electrical, physical, mechanical, or acoustical signals in a single system. In addition, per-channel ADCs and individually isolated modules ensure fast, accurate, and safe measurements.NI CompactRIO PlatformWhen used with the small, rugged CompactRIO embedded control and data acquisition system, NI C Series analog input modules connect directly to reconfigurable I/O (RIO) field-programmable gate array (FPGA) hardware to create high-performance embedded systems. The reconfigurable FPGA hardware within CompactRIO provides a variety of options for custom timing, triggering, synchronization, filtering, signal processing, and high-speed decision making for all C Series analog input modules. For instance, with CompactRIO, you can implement custom triggering for any analog sensor type on a per-channel basis using the flexibility and performance of the FPGA and the numerous arithmetic and comparison function blocks built into NI LabVIEW FPGA.Analysis SoftwareNI 9233/9234 modules are well-suited for noise and vibration analysis applications.

NI9234振动信号接收

阻带
滤波器将显著减弱所有高于阻带频率的信号。主要目的是防止产生混叠。因此，阻带频率与采样率之间存在精确的比例关系。阻带抑制是滤波器对阻带内所有频率信号应用的最小衰减值。
无混叠带宽
NI 9234 的无混叠带宽范围内的信号不是高频信号的混叠。无混叠带宽是由滤波器抑制高于阻带频率信号的能力定义的，无混叠带宽等于采样率减去阻带频率。

923 FILTERS 快速入门指南说明书

Quick Start Guide923 FILTERSLegendary Analog Dual Filter Module for EurorackControls(1) LOW PASS – This knob controls the threshold or “cutoff”frequency for the low pass filter. The low pass filter willroll off all frequencies above this threshold frequency. (2) LOW PASS IN/OUT – Route the incoming signal into thelow pass filter via the IN jack, and then send the outgoing,filtered signal back out via the OUT jack. Connect theincoming and outgoing signals by using cables with3.5 mm TS connectors.(3) HIGH PASS – This knob controls the threshold or “cutoff”frequency for the high pass filter. The high pass filter willroll off all frequencies below this threshold frequency. (4) HIGH PASS IN/OUT – Route the incoming signal into thehigh pass filter via the IN jack, and then send the outgoing,filtered signal back out via the OUT jack. Connect theincoming and outgoing signals by using cables with3.5 mm TS connectors.(5) NOISE SOURCE/WHITE – Use these parallel jacks tosend out a white noise signal via cables with 3.5 mmTS connectors.(6) NOISE SOURCE/PINK – Use these parallel jacks tosend out a pink noise signal via cables with 3.5 mmTS connectors.Power ConnectionThe 923 FILTERS module comes with the required power cable for connecting to a standard Eurorack power supply system. Follow these steps to connect power to the module. It is easier to make these connections before the module has been mounted into a rack case.1. Turn the power supply or rack case power off anddisconnect the power cable.2. Insert the 16-pin connector on the power cable into thesocket on the power supply or rack case. The connector hasa tab that will align with the gap in the socket, so it cannotbe inserted incorrectly. If the power supply does not havea keyed socket, be sure to orient pin 1 (-12 V) with the redstripe on the cable.3. Insert the 10-pin connector into the socket on the back ofthe module. The connector has a tab that will align with thesocket for correct orientation.4. After both ends of the power cable have beensecurely attached, you may mount the module in a case andturn on the power supply.InstallationThe necessary screws are included with the module for mounting in a Eurorack case. Connect the power cable before mounting. Depending on the rack case, there may be a series of fixed holes spaced 2 HP apart along the length of the case, or a track that allows individual threaded plates to slide along the lengthof the case. The free-moving threaded plates allow precise positioning of the module, but each plate should be positionedin the approximate relation to the mounting holes in your module before attaching the screws.Hold the module against the Eurorack rails so that each of the mounting holes are aligned with a threaded rail or threaded plate. Attach the screws part way to start, which will allow small adjustments to the positioning while you get them all aligned. After the final position has been established, tighten the screws down.LEGAL DISCLAIMERMusic Tribe accepts no liability for any loss which may be suffered by any person who relies either wholly or in part upon any description, photograph,or statement contained herein.
