The USB-4431 is a 24-bit high-speed dynamic signal capture USB module with four analog input channels and an analog input range of +/- 10V, providing up to 102.4 kS/s simultaneous sampling per channel. The USB-4431 also features software-selectable AC or DC coupling input settings and built-in 2 mA excitation current to measure integrated electronic piezoelectric (IEPE) sensors such as accelerometers and microphones. In addition, the USB-4431 is equipped with an analog output channel with an analog output range of +/- 3.5V and an output bandwidth of 43.5 kHz.
The USB-4431 cannot expand the number of channels.
It can be equipped with DynaView vibration sound spectrum analysis software to form a 4-channel spectrum analyzer.
