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.
HTH --Till
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.
