B u i l d i n g F o r w a r d To g e t h e r USB-2405 4-CH 24-Bit 128kS/s Dynamic Signal Acquisition USB 2.0 Module Features Hi-Speed USB 2.0 USB bus powered 24-bit Sigma-Delta ADC with built-in anti-aliasing filter 4-CH simultaneous sampling analog inputs, up to 128kS/s AC or DC input coupling, software selectable Analog or digital triggering Supports 2mA excitation output on each analog input channel for IEPE sensor measurement F ull auto-calibration Supporting Time-Frequency analysis software -- Visual Signal DAQ Express Introduction The USB-2405 is a 24-bit high-performance dynamic signal acquisition USB module equipped with 4 analog input channels providing simultaneous sampling at 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 filtering, suppressing modulator and signal out-of-band noise and providing 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 for efficient data acquisition with no need for postprocessing. The USB-2405 is USB bus-powered and equipped with BNC connectors and removable spring terminals for easy device connectivity. Supported Operating System Software Utility LabVIEW, MATLAB, C/C++, Visual Basic, Visual Studio.
