32 Channel ADC for VMEbus – VME393

The VME393 32-Channel Differential Input ADC VMEbus Board is very well suited to be used in applications in which autonomous signal conversion is an issue, as well as in standard mid-range applications. Enabled channels are scanned at maximum rate and conversion results are stored in shared memory. Input channels are grouped into 4 sections of 8 inputs each. Each section features a local DSP which performs all functionality and user specific functions can be added for customized operation.
This VMEbus board has a 6U form and is also available as 3U VMEbus board.
