Spectral Dynamics Introduces the VX2805 Eight-channel Data Acquisition Module at the 74th Shock & Vibration Symposium

San Diego, CA – The Advanced Research Products group of Spectral Dynamics, (SD) announced the introduction of the Spectral Dynamics' VX2805 Eight-channel Data Acquisition Module today at the 74th Shock & Vibration Symposium in San Diego.

The Model VX2805 is a complete integrated 8-channel data recording VXI module. VX2805Each channel includes a bridge signal conditioner, a low pass filter, a 16-bit 5M samples/sec/channel ADC, and 16M samples of DRAM storage per channel.

Built-in signal conditioning is suitable for strain gauge bridge-type transducers and for voltage signals. Constant voltage excitation is independent y programmable for each channel. Special function signal conditioning requirements can be accommodated with the SIPS (Smart Interface Panel System) product family and controlled by the VX2805 onboard processor. Input full-scale sensitivity is programmable from ▒10mV to ▒5V in 3dB steps. A 16-bit ADC provides high accuracy, a high dynamic range and resolutions from 340nV to 170ÁV per count. Offset correction range is ▒2.5V with 16-bit resolution.

A dedicated signal processor in each channel provides superb digital filtering. Filter FCO auto-tracks the sample rate, plus custom filter down load capabilities. Dedicated hardware can generate a trigger from the analog signal being digitized on Channel #1 using either level and slope, or window criteria. Trigger Hold-off can be invoked to reject thresh old crossings of short duration. Hold-off can improve triggering reliability under noisy signal conditioning

Spectral Dynamics, Inc. is a leading worldwide supplier of systems and software for advanced computer-automated data acquisition, vibration testing, structural dynamics, explosive shock, high-speed transient capture, acoustic analysis, monitoring, measurement, control and backup.
