1. AR2FL/S and No/Lo Gain followup Campion Anton Mitch

2. Chip 2 Ch 14 AR2FL Problem on module was reproduced July 21. Not Present mounted on Module with a 10pF loaded PIB replacing straw Reduced in magnitude on module with improved RF finger connection.

3. No Gain Channels External pulser investigation One of several low gain channels responding to an external test pulse input. The pulse amplitude is chosen to cause the same response as a 50mV step in a normal channel.

4. Internal Pulser Demonstrating No/Lo Gain Channels Algen ‘A’ wheel Board #124180
