TGBT15A_915_62 - continued balance testing
See
CICADAGreenBankSpectrometer2016Sep07
Details:
11:00am - Justin switches to new version. Start again at mode 10
11:25am CheckMode10 Scan 16
Bank A took too long to be ready. Repeat, scan 17
All of IF Rack 1,2,5,7 cannot balance because signal is too weak. Yet no error message from Astrid
IF levels are around 0.5V, when the target is 3V. Attenuators are at 0dB (i.e. minimum).
This should be a warning message!
CheckMode11, Scan 18 - same issue with IF rack. Also Mode 12.
Mode 12, Scan 19 - aborts due to invalid data
Get Amber to TaskMaster restart everything
Mode 12 again, Scan 20
VEGAS aborts again - give up at this point!
Nothing obvious Ray can do, so stop testing and wait for Joe to return
Justin switches back
Scan 21 - aborts because Antenna is back in system
Scan 22 - mode 12 - data looks fine.
noon - finito
