SNS BLM uses VME ICS110BL module (ICS company).
32 channels and 16/24 bits. The module is expensive :( Company has
another only 16 bits module but company said that it will not be
cheaper.

I also tried to find 16 bits and 32 channels module but there is not big
chance. Maybe you will be more lucky :)

Good luck - Andrei Liyu.

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.
