CPCI393

8-channel 12-/16-bit differential input ADC Module

The CPCI393 is an 8-channel differential input ADC CompactPCI board, ideal for applications in which autonomous signal conversion is an issue, as well as in standard mid-range applications.

This CompactPCI format is intended for space, weight and power sensitive high frequency sonar applications, including remote mine hunting systems based on unmanned or autonomous underwater vehicles (UUVs/AUVs). Enabled channels are scanned at maximum rate and conversion results are stored in shared memory. A local DSP performs the data acquisition and calibration transparent for the host.

This CompactPCI card is available in a 3U and a 6U form factor.
