ADLINK Unveils USB 2.0 Signal Acquisition Module

Featuring low temperature drift, built-in anti-aliasing filters, support flexible trigger mode, and USB bus power, the portable module is a solution for time-frequency analysis and research.

The module supports four analogue input channels simultaneously sampling up to 128kS/s, and delivers 100dB dynamic range and -94dB THD of dynamic performance. The 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 minimises 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, optimise accuracy in spite of the environment.

Flexible sampling rate, and built-in DDS (direct digital synthesis) generate a programmable sample clock with superior frequency resolution, enabling resolution of 3x10-4 S/s. In addition, the module supports external digital/analogue trigger source, and flexible trigger modes including post, delay, middle, gated, pre-trigger, and re-trigger.

Lockable USB enhances connectivity, and the included multi-functional stand fully supports desktop, rail, or wall mounting. ADLINK's U-Test software is included at no extra charge. The module 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.
