The USB-2405 is a 24-bit, high-performance dynamic signal acquisition USB module with four analog input channels, providing simultaneous sampling of up to 128 kS/s per channel. It also features software-selectable AC or DC coupling and a built-in, high-precision 2 mA excitation current, so it can measure integrated electronic piezoelectric (IEPE) sensors such as accelerometers and microphones.
The USB-2405 delivers high-accuracy DC and dynamic measurement performance with very low temperature drift. The on-board 24-bit Sigma-Delta ADC supports anti-aliasing filters, modulator rejection and out-of-band noise suppression.
The USB-2405 supports both digital and analog trigger sources and flexible trigger modes, including post, delay, middle, threshold and pre-trigger, so data can be captured efficiently without extra post-processing. It is powered by the USB bus and equipped with BNC connectors and a detachable spring terminal block for simple wiring.
Combined with DynaView vibration/acoustic spectrum analysis software, it forms a four-channel spectrum analyzer.
