PCI-4461 NI Sound and Vibration Device

The National Instruments PCI‑4461 (Part number: 779307-01) is a high-precision data acquisition module particularly intended for sound and vibration applications. This device gives synchronous two-channel dynamic signal generation and concurrent two-channel dynamic signal securing with six pick-up settings to design the input range. The PCI‑4461 NI incorporates programming configurable AC/DC coupling and integrated electronic piezoelectric (IEPE) molding to guarantee exactness estimations with receivers, accelerometers, and different transducers that have huge unique reaches. Basic applications incorporate sound test, automotive test, noise, vibration, harshness (NVH) analysis, and machine condition checking.

The analog information channels of the NI PCI‑4461 have 24-bit resolution ADCs that are tested at programming programmable rates for standard sound applications, such as 44.1 kS/s (the standard rate utilized for CD players), 48.0 kS/s, the rate utilized as a part of digital audio tape (DAT) recorders and other computerized sound hardware, 96.0 kS/s, and 192 kS/s. It has a Delta–sigma ADC type. A programmable pick up intensifier arranged on the information sources gives pick up determination from – 20 to +30 dB in 10 dB steps. Moreover, to give the user the calmest and most noteworthy quality analog estimations, the input stage acknowledges differential or single-finished signal associations.
