Testing on July 10, 2014

Purpose:

• Run some fidicual scans for the apparent frequency switch problem

Info:

• TGBT14A_912_05

Plan:

• total power, no cal in mode 4.
• total power, cal, no doppler in mode 4
• frequency switch, no doppler in mode 4
• total power, cal, doppler in mode 4
• frequency switch, doppler in mode 4.
• Repeat for mode 24
• Run it as fast as possible.
• Do at L-band with noise source on one polarization. Running noise source on four banks.

• Let's also try one with only doppler tracking.

Log:

• Jason hooked it up so that odd numbers have noise source.
• 3 scans of 60s.
• Scan 33-36: tsys_issue_mode4_nocal_nofsw_nodoppler. tint=0.01 (max for mode).
• Scan 37-39: tsys_issue_mode4_cal_nofsw_nodoppler. tint=0.028 (max for mode with noise diode, no doppler). looks like bary was set in the config, but I'm slewing to 3C147 and lo1 doesn't appear to be updating, so we aren't doppler tracking. Might want to re-run.
• Scan 40: tsys_issue_mode4_cal_fsw_nodoppler. tint=0.32s (max for mode with noise diode, fsw, no doppler). had keywords wrong. Trying again
• Scan 41-43: tsys_issue_mode4_cal_fsw_nodoppler. tint=0.32s.
• Scan 44-46: tsys_issue_mode4_cal_nofsw_doppler. tint=0.38s
• Scan 47-49: tsys_issue_mode4_cal_fsw_doppler. tint=0.38s.
• Scan 50-52: tsys_issue_mode4_cal_nofsw_nodoppler. tint=0.028. repeating to make sure not doppler tracking.
• Scan 53-55: tsys_issue_mode24_nocal_nofsw_nodoppler. tint=0.0727s
• Scan 56-58: tsys_issue_mode24_cal_nofsw_nodoppler. tint=.447s
• Scan 59-61: tsys_issue_mode24_cal_fsw_nodoppler. tint=0.895s
• Scan 62-64: tsys_issue_mode24_cal_nofsw_doppler. tint=0.447s
• Scan 65-67: tsys_issue_mode24_cal_fsw_doppler. tint=0.895s
