The National Instruments USB-4431 is a state-of-the-art Sound and Vibration Device that falls under the category of PC-based Dynamic Signal Analysis (DSA). The product carries a corrected part number 780164-01, originally listed as 198755D-01L.
This device is equipped with a robust five-channel dynamic signal acquisition system, which includes four differential analog input channels and a single output channel. It boasts an impressive dynamic range of 100 dB, ensuring high fidelity in sound and vibration measurements.
One of the key features of the USB-4431 is its software-selectable signal conditioning, making it adaptable for use with both accelerometers and microphones. This flexibility is complemented by a variable sampling rate that ranges from 2 kS/s to 102.4 kS/s, allowing for a wide range of measurement scenarios.
The device’s power consumption is efficient, capped at up to 2.5 W, which is quite economical for its capabilities. It operates with a high degree of precision, thanks to its 24-bit ADC resolution and simultaneous sampling mode. This ensures that all channels are sampled at exactly the same moment, eliminating timing discrepancies between channels.
Accuracy is further enhanced with a sample rate accuracy of ±100 ppm maximum, ensuring reliable measurements. The input range of ±10V and input protection of ±60V safeguard the device against unexpected voltage spikes, while the output signal range of ±3.5V caters to a variety of output requirements.
