System compatibility

PCI-4472 belongs to NI DSA dynamic signal acquisition platform.It works with standard PCI industrial PC,supported by NI-DAQmx driver and LabVIEW,widely used for multi-channel acoustic noise,vibration,NVH and audio frequency measurement in legacy test systems.It is spare part for legacy test equipment overhaul.

Function

PCI-4472 is 8-channel high precision DSA board for sound and vibration shturl.cc/ provides IEPE power supply for accelerometers and microphones,with built-in automatic anti-aliasing filter.Eight channels sample synchronously for FFT spectrum analysis.RTSI bus supports multi-card synchronization to expand measurement channels for large-scale multi-point vibration test systems.

Installation

Insert PCI-4472 into computer PCI slot and fasten bracket.Connect sensors to SMB connectors.Install NI-DAQmx driver.Take ESD protection before installation.

Interface

‑9×SMB analog input & trigger connectors

‑PCI gold finger edge connector

‑Board status indicator

Feature

PCI-4472 classic NI 8-channel sound & vibration DSA board.Typical faults:SMB connector oxidation,IEPE excitation circuit failure,ADC measurement drift.Inspect sensor wiring and spectrum test before replacement.

Diagnostic

Fault phenomenon:no signal input,high background noise,channel inconsistency.Check SMB cable,transducer,PCI slot contact,NI-DAQmx driver and IEPE/coupling configuration.

Product Brief

PCI-4472 is NI PCI bus 24-bit 8AI DSA board with max 102.4kS/s sampling rate,supporting IEPE and RTSI synchronization,for multi-channel acoustic,shock vibration and NVH testing and legacy dynamic test equipment renovation.Mainly used for maintenance and replacement of old test equipment.ESD protection must be followed during handling.
