TGBT14A_912_78 - Continued bank discrepancy problems

Goals

• Run Glenn's cal switching driven external to VEGAS test

Details

• Start at 11:00am
• Edit vegas.conf to up sampler rate to 50ms (20 Hz).
• Turn Managers off and on, and switch modes, to ensure samplers are updated.
• Managers start crashing, and VEGAS CLEO display dies. Maybe sample rate is too high?
• Vegasdm doesn't update any faster, but CLEO VEGAS screen is updating power values ar around 20Hz now.
• bank_gain_mode1_cband_nocal
• balance - looks good. Both pols behaving.
• Scan 1 - 60 sec test scan. Archivist file has 741 rows, = ~ 12Hz. I guess that is the fastest it can keep up with?
• Try setting tint/swper to 0.5 secs, and DCR switching period to be 4 secs
• bank_gain_mode1_cband_nocal_fast
• Add DCR to scan coordinator
• Scan 2 - 60 sec scan - switching signal master has switched back to VEGAS
• Scan 3 aborts due to DCR unexpected sig/ref state... what have I not configured correctly?
• VEGAS still thinks it is the switching signal master - does this matter?
• Set VEGAS switching signal master to be DCR, but switching source remains "internal" for each Manager
• DCR aborts again...
• try running this the other way around. Configure for DCR, but include VEGAS into scan later?
• try removing VEGAS from scan coordinator
• same problem - try a DCR "conform parameters" - same problem.
• Configure back to VEGAS in charge...
• VEGAS (Bank A) is now controlling noise diode.
• CLEO device explorer is now hung up... use "more info" from VEGAS CLEO screen.
• I cannot figure this out. Configure for tp_nocal, 0.5 sec integrations, samplers running at ~ 12.5Hz.
• Run a 1 min scan with no noise switching, but toggle the noise diodes off and on manually.
• Scan 7, noise diode manually toggling
• vegasdm was not updating, also rcvr screen diode display did not update...
• no sign that anything was happening
• try again - don't seem to be able to change noise diode values while scan is running
• Give up with this, and set everything back to normal (including vegas.conf)
• finish at 12:00
