MLDaq channels for 1L03 GMES1, PMES1 and GASK1-4 and PASK1-4 seem to have a problem

There has been some discussion in the background about the potential for microphonics issues on 1L03 as indicated by the MLDaq waveform data. There is a copy of the same waveforms on the front panel connectors on the RFCM analog boards. Jayendrika and I went out this afternoon with an oscilloscope and took data for the analog GMES, PMES (really PLDE), GASK and PASK signals so that they could be compared to the data from the MLDaq system. It seems that 6 of the channels in the MLDaq system have a problem.

2L13-8 Tuner Issue with Sluggish/slow Behavior

1 day 11 hours ago
Log Number: 4492259Logbook(s): Entry Makers: kernsBody: 

After SRF found nothing wrong with the tuner downstairs, I suggest we replace the Camac M540 Micro-stepper card during our next maintenance day ! Never saw a stepper card cause sluggish tuning but I was sure we might have some loose set screws on the couple motor coupler. We'll see and eliminate the card. Don't see any differences between cav.7 and cav.8 on the tuner diagnostic page that would account for the tuner being slow ! We'll see.
