Acoustic/vibration measurements with 4-channel 24-bit dynamic signal acquisition unit

July 19, 2013 // By Julien Happich
Adlink Technology has released the USB-2405, a four-channel USB 2.0 dynamic signal acquisition module with a built-in IEPE excitation current source that provides 2mA on each AI channel.

BNC connectors enable the USB-2405 to provide high accuracy and dynamic performance for microphone and accelerometer measurement in vibration and acoustic applications. The instrument features built-in anti-aliasing filters, a flexible trigger mode, and USB bus power. The four analogue input channels simultaneously sample up to 128 ksamples/sec and deliver 100 dB dynamic range and -94 dB THD of dynamic performance. The USB-2405 also supports auto-calibration for ensured accuracy, and minimises temperature drift in the field with maximum gain drift of 11 ppm/°C.

The USB-2405 offers lockable USB to enhance connectivity, and the included multi-functional stand fully supports desktop, rail, or wall mounting.
