4-CH, 24-bit USB-2405 dynamic DAQ module from Adlink

ADLINK has released its new four-channel USB 2.0 dynamic signal acquisition module, the USB-2405. A built-in IEPE excitation current source provides 2mA on each AI channel, and BNC connectors enable the USB-2405 to provide high accuracy and excellent dynamic performance for microphone and accelerometer measurement in vibration and acoustic applications. Featuring superior accuracy with low temperature drift, built-in anti-aliasing filters, support for flexible trigger mode, and USB bus power, the USB-2405 embodies an ideal portable solution for time-frequency analysis and research. High Accuracy with Low Temperature Drift The ADLINK USB-2405 supports four analog input channels simultaneously sampling up to 128kS/s, and delivers 100 dB dynamic range and -94 dB THD of dynamic performance. Built-in anti-aliasing filters enable filter cutoff frequency to be automatically adjusted to the sampling rate, suppressing out-of-band noise and avoiding measurement distortion. The USB-2405 also supports auto-calibration for ensured accuracy, and minimizes temperature drift in the field with maximum gain drift of 11ppm/°C, an impressive 50% of the maximum available market performance. The USB-2405’s low DC measurement drift, along with temperature deviation, optimize accuracy in spite of the environment. Flexible Sampling Rate & Triggering The ADLINK USB-2405 provides flexible samplin...
