Cryomodule commissioning: completed 1-hour runs on cavity 5 and 6, some work on cavity 7 and 3

Cavity 5:
Q_FPC = 1.67e7, Q_FP = 2.4e12
Emax 21 MV/m, 750 mR/hr, FE Onset 18 MV/m

Cavity 6:
Q_FPC = 1.48e7, Q_FP = 1.5e12
Emax 21 MV/m, 1000 mR/hr, FE Onset 16 MV/m
During 1-hour run, noticed Forward/Reflected power would droop (3.2 -> 2.9 kW) for a few minutes then recover. Caused a 21 -> 20 MV/m droop in cavity gradient.

The current readback for the faraday cups does not respond to tune mode beam. We tried rebooting iocinj4 and iocsoftinj1 to no avail. I recall a previous fix that involved switching from autorange to a specific range and back, but this didn't help either. The linked log entry mentions a GPIB controller communicating slowly, diagnosed by way of blinkenlights, and a potential solution. The referenced "talk" LED on said controller is blinking roughly once per second. I am not sure if that is fast or slow.
