The National Instruments PCI-4461 is a sound and vibration device that offers 24-bit resolution across two dynamic signal generation and acquisition channels, with a dynamic range of 118 dB and a frequency range of DC to 92 kHz, suitable for various
The National Instruments PCI-4461 Sound and Vibration Device, part number 779307-01, is designed to deliver high-precision data acquisition for sound and vibration analysis with its integrated 2-channel dynamic signal generation and acquisition.
Featuring AC/DC configurable coupling and integrated IEPE conditioning, this device is well-equipped for precise measurements with various transducers. The 24-bit resolution ADCs provide clear and accurate data capture, and users can choose from multiple sampling rates, including 44.1 kS/s, 48.0 kS/s, 96.0 kS/s, and 192 kS/s, to match the requirements of standard audio applications.
The delta-sigma ADC type and an input gain range of -20 to +30 dB in 10 dB steps ensure flexibility in signal processing, while the impressive 118 dB dynamic range and frequency range from DC to 92 kHz allow for capturing a wide spectrum of sounds. With a typical Total Harmonic Distortion (THD) of -107 dB, the PCI-4461 ensures high-fidelity recordings.
Moreover, the device accommodates both analog and digital triggers, enhancing its versatility in various testing scenarios. It is also relatively lightweight at 8.5 oz and compact with dimensions of 6.3 x 3.9 inches, making it an easy fit for most work environments.
