Description
The National Instruments PCI-4461 Sound and Vibration Device is a PC-based Dynamic Signal Analysis (DSA) solution, designed for a wide range of applications. This high-performance device can be identified by its part numbers 778442-03 (Primary) and 779307-01. It is particularly suited for tasks such as sound test, automotive test, noise, vibration, harshness (NVH) analysis, and machine condition monitoring.
At the heart of its capabilities are 2 input channels which, combined with a 24-bit ADC resolution, allow for precise data acquisition. The device supports multiple sampling rates, including 44.1 kS/s, 48.0 kS/s, 96.0 kS/s, and 192 kS/s, providing flexibility in capturing data for various test scenarios. The ADC employs a Delta-Sigma type for high-fidelity signal processing.
With its Programmable Gain Amplifier, adjustable from -20 to +30 dB in 10 dB steps, users can optimize signal levels for analysis. The device boasts a dynamic range of 118 dB and a frequency range from DC to 92 kHz, ensuring broad application coverage from low to high frequencies. Signal integrity is maintained with an amplitude levelness of ±0.1 dB, and a total harmonic distortion (THD) rating of -107 dB, demonstrating the device’s ability to provide clean, accurate measurements.
For enhanced data acquisition control, the PCI-4461 includes both analog and digital trigger options, allowing users to precisely start measurements based on specific conditions. This level of control is vital for conducting sophisticated tests and analyses.
