Description
The NI PCI-4461 is identified by its part number 779307-01 and is a high-performance baseboard designed for a variety of applications including sound test, automotive test, NVH (Noise, Vibration, and Harshness) analysis, and machine condition monitoring. This device is capable of delivering exceptional accuracy and detail in measurements thanks to its 24-bit ADC resolution.
It offers a range of sampling rates including 44.1 kS/s, 48.0 kS/s, 96.0 kS/s, and 192 kS/s, making it versatile for various high-precision testing scenarios. The delta-sigma ADC type further enhances its performance in capturing high-quality data.
The NI PCI-4461 allows for gain adjustment from -20 to +30 dB in 10 dB steps, offering flexibility in signal analysis. It supports both differential or single-ended input types, accommodating a wide range of sensors and signal sources. With a dynamic range of 118 dB and a frequency range from DC to 92 kHz, it ensures detailed and accurate capture of audio and vibration signals.
The board’s total harmonic distortion (THD) is impressively low at -107 dB, indicating its ability to measure signals with high fidelity. It is equipped with both analog and digital trigger types, providing versatility in setting up measurements and tests. The device is notably compact, with dimensions of 6.3 x 3.9 inches and a weight of 8.5 oz, making it easy to integrate into various test setups.
