TGBT14A_912_64 - continue bank discrepancy problems

• Start at 11:00am
• Write a procedure Archivist to configure the archivist correctly.
• Need to set up for KFPA, since the are working on the MUSTANG rotator
• Can only use four banks; config_tool seems to chose E,F,G,H
• Has configured with some blanking for some reason, but otherwise, all looks correct. Has balance ok.
• Switch to mode 4 - still seems to have configured correctly.
• now use Balance target levels and Balance() to iterate through input levels, allowing config_tool to choose values of lbw_gain.
• run bank_gain_mode4_kfpa
• run checkLinearityBalance
• first scan (at target -36dB) is scan 8
• last scan (at target -14dB) is scan 18. Go to -10dB Takes around 20 minutes
• What happened to scan 19?
• configure for mode 7.
• run checkLinearityBalance - failed with some VEGAS errors; try again
• Same again; turn manager off and on again; still errors; Xdisplays hang up for a few minutes...
• Finally get started on mode 7; scan 23 <=== forgot to change mode number....
• for the higher input level, e.g. -10dB, the filtersnap measpwr has gone up, but the histograms still look lousy check this_
• running out of time, so concentrate more on the high end of the target range,
• 37, VEGAS mode 9, initial target -30dB
• looks like they may be extending the boom???? Scan 38 screwed up. Next one might be ok. No, they are moving telescope in elevation...
• input power is changing by about 2dB during a scan; maybe need to use a subset of the data.
• Scan 49 has target level -6dB
• Switch to mode 11 - note they are now slewing the telescope back to access. But I can't wait for them to finish...
• Green channel (pol 1) is much less sensitive to slewing than red channel (pol 2)
• run checkLinearityBalance again: mode 11, scan 50 to start at -30dB
• mode 24 - Bank G gets stuck in activating, recovers on next attempt, then fails again. Restart.
• mode 24, scan 62, target - 30dB
• Finish at 4:10pm
• Finito!
