General Standards Inc. makes a PMC module
with 64 parallel 16-bit digitizers. It can be
configured to 64 single-ended, 32 differential
(digital differences!) channels. Very compact
and not extremely expensive (3.5k); EPICS
drivers available.

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.
