1 Introduction
1.1 Overview
The USB-2405 is a 24-bit high-performance dynamic signal acquisition USB module, equipped with 4 simultaneous-sampling analog input channels sampling up to 128 kS/s per channel. The
USB-2405 also features software selectable AC or DC coupling
input configuration, and built-in high precision 2 mA excitation current to measure integrated electronic piezoelectric (IEPE) sensors
such as accelerometers and microphones.
The USB-2405 delivers high precision DC and dynamic measurement performance with very low temperature drift. The onboard
24-bit Sigma-Delta ADC supports anti-aliasing, which suppresses
modulator and signal out-of-band noise and provides usable signal bandwidth of the Nyquist rate, making it ideal for high dynamic
range signal measurement in vibration and acoustic applications.
The USB-2405 supports digital and analog trigger sources and
flexible trigger modes, including post, delay, middle, gated, and
pre-triggering, which acquires data efficiently without post processing. The USB-2405 is USB bus powered and equipped with
BNC connectors and removable spring terminals for easy device
connectivity.
