Description
NI PCI‑4552 Dynamic Signal Acquisition Board – Precision sound and vibration capture for PC-based test
The NI PCI‑4552 is a legacy dynamic signal acquisition (DSA) board designed for audio, acoustics, and vibration measurements directly from a standard PCI slot. From my experience, it’s the kind of card teams keep in service because it delivers stable, low‑noise measurements with built‑in anti‑aliasing and IEPE support for microphones and accelerometers. You might notice that, compared with general DAQ, DSA hardware like this typically offers 24‑bit resolution, simultaneous sampling, and filtering tailored for condition monitoring, modal testing, and sound quality work.

Key Features
- Dynamic Signal Acquisition (DSA) front end: Optimized for sound and vibration, with simultaneous sampling and precision anti‑alias filtering.
- IEPE/ICP sensor support: Excitation for accelerometers and microphones, so you can connect transducers directly without external conditioners.
- Audio‑bandwidth performance: Suitable for order tracking, modal analysis, and acoustic testing where low noise and flat phase response matter.
- PCI bus integration: Powered from the PCI slot—no external supply—keeping setups simple inside a desktop or industrial PC.
- Signal integrity by design: Shielded inputs and matched filtering that typically reduce aliasing and hum in lab and production environments.
- Software ecosystem: Commonly used with LabVIEW and sound/vibration toolkits; driver support is usually via Traditional NI‑DAQ for this generation (verify OS compatibility).
Typical Use Cases
- End‑of‑line acoustic checks for small motors or fans where a quick frequency signature pass/fail is needed.
- Vibration trending on test benches—collecting simultaneous multi‑channel data during durability runs.
- Microphone array measurements for noise source identification in R&D labs.
One thing I appreciate is how reliably it syncs data across channels—teams doing order analysis tell us the phase coherence seems to be very stable over long captures.

Related or Supporting Products
- NI PCI‑4472 – Successor‑class 8‑channel DSA with broader software support; often chosen when more channels per card are needed.
- NI PCI‑4462 – High‑resolution DSA with simultaneous inputs; good for lab upgrades where PCI must be retained.
- NI PCI‑4461 – Similar to 4462 but with simultaneous analog outputs for stimulus/response testing.
- NI PXI‑4472B – PXI form factor alternative if you are consolidating into a modular chassis.
- NI USB‑4431 / USB‑4432 – Portable DSA options if a laptop/USB workflow is preferred.
- Software: LabVIEW Sound and Vibration Toolkit; order tracking and spectral analysis functions accelerate setup for production tests.
A customer running fan acoustic EOL stations swapped legacy 4552s with PCI‑4472 units only because their OS image moved forward; the data quality difference was minimal, but driver availability simplified IT approval. That’s a typical path if you’re modernizing.
Installation & Maintenance
- PC & cabinet: Install in a clean, ventilated PC chassis with a free full‑height PCI slot; avoid stacking high‑power GPU/PSU cabling directly over the board.
- Grounding & cabling: Use shielded sensor cables; keep analog leads away from switching supplies. Tie shields at one end to reduce ground loops.
- Drivers & OS: This model is commonly supported by Traditional NI‑DAQ. Verify operating system compatibility before field deployment (many teams lock an image that is known‑good).
- Calibration: Annual calibration is typical for audit‑bound test labs; retain the calibration report with unit serial for traceability.
- Routine checks: Inspect connectors, run a quick self‑test and a loopback spectrum weekly on production lines to catch drift or loose leads early.
- Firmware/Software: Keep LabVIEW toolkits aligned with the driver version; in many cases, newer toolkits can work if the driver remains supported on the OS.
Quality & Certifications
- Manufacturer quality systems: ISO 9001
- Electrical safety and EMC: CE marked; UL/IEC I.T.E. safety categories typically applicable to this class
- RoHS status may vary by production date for legacy hardware; confirm per unit if required for your site policy
- Seller warranty: 365 days, with functional test prior to shipment
Quick tip: If you plan to synchronize multiple PCI‑4552/DSA boards, budget a few extra minutes to set up the RTSI clock lines in software—once mapped, it’s stable, but the first‑time mapping can be a small gotcha.
