National Instruments PCI-4461 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.

This model comes with 118 dB dynamic range and low noise and distortion. The NI PCI 4461 Sound and Vibration Device can make extremely precise frequency area estimations. This model has an astounding abundancy levelness of ±0.1 dB inside the frequency range of DC to 92 kHz and with a common THD of - 107 dB. The PCI 4461 possesses both an analog and digital trigger. The device weighs 8.5 oz, and has the dimensions: 6.3 x 3.9 in. Also, it has a PCI or PXI bus interface with a 3.3 V or 5V signal environment; and 1 analog input DMA channel.

The NI 4461 is a NI Dynamic Signal Acquisition Product which operates on NI-DAQmx driver software. Installing the NI-DAQmx software requires the presence of an Application Development Environment such as NI LabVIEW, ANSI C, or Visual Basic .NET. The PCI 4461 has BNC female analog I/O connectors and an SMB male digital trigger connector.

The PCI-4461 is available to be calibrated. While the recommended calibration period for individual parts varies, most parts should be calibrated either annually or every two years to ensure accuracy. If you need the PCI-4461 calibrated, Apex Waves provides options. We offer high-quality NIST accredited calibrations through a 3rd party, with an average turnaround time of 1 to 2 weeks. When you order the PCI-4461 with us, you can request basic (unaccredited) in-house calibration that will calibrate the part to the manufacturer specifications prior to being shipped.
