Further tests of wideband VPM configurations for C-Band, X-Band, and KFPA for Tim Pennucci's GC magnetar project (AGBT17A _433)
Details
Session begins at 15:15.
Submitting VPM_C-Band_Test SB using vegas.scale = 14000 and rest frequencies of 4312.50, 5437.50, 6562.50, and 7687.50 MHz
Scans #1/2 are cal and search mode, with noise diode firing in each case for test purposes
Scans seemed to run fine
Submitting VPM_X-Band_Test SB using vegas.scale = 14000 and rest frequencies of 8562.50, 9687.50, and 10812.520 MHz
Scans #3/4 are cal and search mode, with noise diode firing in each case for test purposes
Scans seemed to run fine
Submitting VPM_KFPA_Test SB using vegas.scale = 14000 and rest frequencies of 19375.0, 20500.0, 21625.0, 22750.0, 23875.0, 25000.0, and 26125.0 MHz
Scans #5/6 are cal and search mode, with noise diode firing in each case for test purposes
Scans seemed to run fine
Will check frequency precision in shared memory viewers in coherent mode now
Submitting CoherentModeTests to take c0800x0512 and c0800x1500 cal mode scans
Got an abort, not sure why
Ah! It's the dopplertrackfreq issue! Added a ResetConfig command
The frequency precision looks OK except that Bank H is calculating the wrong center frequency. It's not getting the right sideband value for some reason.
Ray is trying to diagnose but doesn't see an obvious way this could happen
Cannot solve now. Will do some spectral line checks
Reverted back to old manager without the higher frequency precision
