TGBT14A_912_53 - Bank to Bank discrepancy tests, as well as KFPA rms noise tests
Goals
Details
Goals
Check if Mode 3 shows the Bank to Bank Discrepancy
Check if altering the lbw_gain such that pol2,measpwr to -20dB solves the problem
Details
Scan 1 : L-band centered 1420 MHz Mode 3 (1080 MHz bandwidth) in all 8 banks
All results to within 1-2%
Scans 7/8: X-band centered at 8584.82315 MHz Mode 5 (187.5 MHz bandwidth) in all 8 banks (
OffOn
pointing switch)
Set the lbw_gain in banks A-E such so the the pol2,measpwr is set to -20dB
Scan 7 not easily readable due to excess prepare. Repeated in scan 10/11
Scans 10/11: X-band centered at 8584.82315 MHz Mode 5 (187.5 MHz bandwidth) in all 8 banks (
OffOn
pointing switch)
Set the lbw_gain in banks A-D such so the the pol2,measpwr is set to -20dB
It appears previously set (manually) values of lbw_gain are being maintained for banks E and F, though the previous values are now incorrect values.
Scan 12: KFPA integration time test (bogus)
Scans (13/14) and (15/16) - KFPA VEGAS 146s nod
Scan 17 - ACS fail
Scans (18/19) and (20/21) - KFPA ACS 146s nod
