Hi Steve,
Joerger Enterprises makes a VME module which has a mother board and up to 4 daughter cards. One version of the daughter card is 8 channels, 14 bits, 10MHz. So you can do 32 channels on one VME board.

Subject: Digitizer needed for LCLS
EPICS colleagues:
The LLNL group that is supplying the diagnostics to commission the
LCLS needs a digitizer for an energy measurement instrument
(calorimeter) with the following characteristics:
- 100 channels sampled simultaneously
- each channel takes 100 samples at 10us per sample (1 ms total time)
- differential inputs
- 12 bits minimum; 14 or even 16 bits preferred
- sampling repeats at 120 Hz major cycle with trigger
A VME or VXI format is ideal.
Any suggestions are most welcome. Ideally, we can discuss this in
depth at the June meeting.
