Purpose Record RF system jitters and store / archive data
Preconditions RF station is running
Preconditions - RF station is running
- AVG gates are set-up for correct length for particular station, P2P count is set to 100 for all channels + vsum
- AMPLT-REFERENCE is set to the klystron saturation point
- feedbacks are in closed loop (both)
- you know the settling time of the feedback + 100 P2P-count + 100 Hz, if required, change it below
