A new four-channel USB 2.0 dynamic signal acquisition module has a built-in IEPE excitation current source that provides 2 mA on each AI channel. BNC connectors enable the USB-2405 from Adlink Technology 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 attractive portable solution for time-frequency analysis and research.

The USB-2405 supports four analog input channels simultaneously sampling up to 128 kS/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. It also supports auto-calibration for ensured accuracy, and minimizes temperature drift in the field with maximum gain drift of 11 ppm/°C, an impressive 50% of the maximum available market performance. The USB-2405’s low DC measurement drift, along with temperature deviation, optimizes accuracy in spite of the environment.

The USB-2405 provides lockable USB to enhance connectivity, and the included multi-functional stand fully supports desktop, rail, or wall mounting. Adlink’s easy-to-use U-Test software is included at no extra charge. With no programming required, the USB-2405 delivers fast, easy instrument setup and quality data acquisition. The USB-2405 supports Windows 8, Windows 7, Windows XP operating systems, and is fully compatible with third-party software such as LabVIEW, MATLAB and Visual Studio.NET.
