ADLINK Introduces 4-CH 24-bit USB-2405 Dynamic Signal Acquisition Module

Ideal for precision microphone and accelerometer measurement in vibration and acoustic applications

ADLINK Technology, Inc. announces the release of 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, optimizes accuracy in spite of the environment.

Flexible Sampling Rate & Triggering

The ADLINK USB-2405 provides flexible sampling rate, and built-in DDS (direct digital synthesis) generates a programmable sample clock with superior frequency resolution, enabling resolution of 3x10-4 S/s. In addition, the USB-2405 supports external digital/analog trigger source and flexible trigger modes—including post, delay, middle, gated, pre-trigger, and re-trigger—all maximizing convenience of use.

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®.
