Do comparison spectrum with Spectrometer and Q-band
Scan 66: RippleQbandMode3 -- input after Galen's IF module (but before convert module).
input is before converter module
Scan 67: RippleQbandMode1 -- no good. need to change attenutation levels.
Scan 68: RippleQbandMode1 -- no good. Still fiddling with attenutation levels.
Scan 69: RippleQbandMode1 -- changed LO freq to 11300 from 15000 because noise source has a bandpass of 800-1400 MHz. Also needed to manually change the convert rack attenuation. Saved cleo config to file to check.
CM1 = 2 dB
CM5 = 8 dB
CM2 = 9 dB
CM6 = 7 dB
Scan 70: RippleQbandMode2 -- paused and got config before running scan.
Scan 71: RippleQbandMode3 -- paused and got config before running scan.
Disconnected cables and handed system over to Melinda for a while.
Scan 74: nchan_test -- trying to see if nchans is now right. VEGAS wouldn't stop, so aborted and will try again.
no scan 75?
Scan 76: nchan_test -- trying to see if nchans is now right
Scan 77: ifnum_test -- ran.
Realized I need to run multiple versions of ifnum_test to see if the problem still exists.
Scan 78-82: ifnum_test -- modified version of ifnum_test to take 5 in a row, then I can see if the pattern repeats.
needed to restart turtle
Scan 83-83: KFPAMode20OnOff1Beams1Spws -- checking that not getting VEGAS bank A manager error. seems to be okay.
Scan 85: RippleQbandSpect -- ripple test with the Spectrometer (whole receiver path)
According to Melinda, change projects to make astrid forget everything. She doesn't remember if you need to do something in the other project.
