Technical Specifications 2 analog input channels; 24-bit resolution; 204.8 kS/s sampling rate; IEPE sensor support; PCI bus interface; Operating temperature 0~55°C.
Functional Features High precision dynamic signal capture. Built-in IEPE constant current source for accelerometers and microphones. Anti-aliasing filter. Time and frequency domain measurement.
Application Scenarios Vibration test, acoustic measurement, noise analysis, modal test, product quality inspection in laboratory and industrial test bench.
Performance Parameters 24-bit ADC; Low noise and high dynamic range; Built-in IEPE excitation for piezoelectric sensors.
Structural Characteristics Standard PCI form factor board, BNC signal connectors on front panel, status LED indicators.
Working Principle The board receives analog dynamic signals from sensors. Anti-aliasing filter removes high frequency noise, ADC converts analog signal to digital data, and transfers digital waveform to PC memory over PCI bus.
Installation Requirements Power off PC, insert PCI board into PCI slot, secure bracket. Install NI DAQmx driver software. Connect sensors via BNC cables.
Usage Notes Use shielded BNC cables for signal input. Do not exceed input voltage range. Enable IEPE power only for IEPE sensors.
