Entry number 333397

Hisham and I went into the Hall this morning to check BMP signals in the 
Left arm. Wires 3 and 4 of each BPM seemed to be saturating yesterday 
with beam.

We checked that attenuators were reading ok (-50mV with a battery of 
1.5V). Signals were correctly plugged into slot 24 of crate 4. We checked 
the gate width, it was 60ns wide. We reduced it to 40ns.

In order to troubleshoot with beam, we plugged 4 output channel after the 
attenuator into the scope (accessible through the web at dvcstlab3):

- Channel 1 of the scope is BPMA, wire 3 (saturating yesterday)
- Channel 2 : BPMA, wire 4 (saturating yesterday)
- Channel 3 : BPMB, wire 3 (saturating yesterday)
- Channel 4 : BPMA, wire 1 (ok yesterday, for reference)
