32-channel 12-/16-bit differential input ADC Board

The VME393 is an 32-channel differential input ADC 6U VMEbus board, ideal for applications in which autonomous signal conversion is an issue, as well as in standard mid-range applications.

This 6U VME multifunction I/O board is ideal for standard mid-range applications, as well as applications in which autonomous signal conversion is an issue.

Enabled channels are scanned at maximum rate and conversion results are stored in shared memory. Input channels are grouped into four sections of eight. Each section features a local DSP which performs all functionality and user specific functions can be added for customized operation.

The VME393 is also available in 3U form factor and as a M-Module, PCI and CompactPCI (3U and 6U) product.
