A/D System

Symmetric Research offers DSPA64/DSPHLF A/D system comprising the DSPA64 and DSPHLF boards. This combination makes a complete system for A/D acquisition and processing. Sitting outside the PC, the DSPA64 card features a high resolution 16-bit A-/D converter and a 64-channel programmable multiplexer array. Sampling at aggregate rates up to 138 kHz, all DSPA64 inputs are differential and buffered through a low-noise precision instrumentation amplifier. In addition, overall gain and amplitude limits can be user set by resistors, with nominal values of 1.0 and ?2.75 V. Connected by a 16-conductor ribbon cable, the DSPA64 communicates all of its acquired data in serial digital format to the DSPHLF card installed inside the PC.
