TGBT14A_912_128 - Mode 4 - 6 config tool tests

Goals

• Check the new center frequency calculations in config tool are correct.

Details

• 1pm Melinda and Joe switch versions
• No log file from Adam, so not quite sure what he did.
• Create ConfigToolMode4Test - simple script to create four windows at 8500 MHz on four banks.
• Scan 1: 8500 MHz topo - All looks fine.
• Create a more complicated configuration:

ResetConfig()
vegas_config="""
bandwidth = 187.5
nchan = "low"
swmode = "tp"
swtype="none"
swper = 10.0
tint = 10.0
vframe = 'lsrk'
receiver= 'Rcvr8_10'
obstype = 'Spectroscopy'
backend = 'VEGAS'
noisecal = 'lo'
vdef = 'Radio'
pol = 'Circular'
dopplertrackfreq=8550
beam = 'B1'
vegas.subband=1
deltafreq=0
vegas.vpol = "self"
nwin=4
restfreq=8400, 8500, 8600, 8700
"""

Configure(vegas_config)
Balance()
source=GetCurrentLocation("J2000")
SetSourceVelocity(2000.0)
Track(source, None,30.)

• Scan 2: velocity = 100
• Scan 3: Velocity = 2000 - all looks as it should
• Scan 4: insert a test tone at 8500, -30dB, run Track, Tone appears exactly where I would expect.
• Melinda switches to old version of Config Tool
• Restart with old version of config tool
• Scan 5: no test tone, window is clearly at the wrong Fsky value (and velocities are out).
• Switch back to new version.
• Since tone comes in at the correct place, no need to test that again. But, check mode 7 just to make sure.
• Scan 6: ConfigToolMode7Test. Looks perfect!
• Scan 7: ConfigToolMode20Test. Looks perfect also!
• 2:20pm - switch to BOF file noise tests...
