TGBT15A_915_137 - VPM Scale and Filter Tests
Goals
Details
Conclusions
Goals
* Test VPM scale factors with 1400 MHz and 950 MHz IF filters for incoherent and coherent 800 MHz modes
Details
Session begins at 14:40
Note: First scan is numbered 6.
Submitting
IncoherentCalTests
with 1400 MHz IF module filter.
Oops. Submitted wrong block. Scans #6 and #7 are i0800x0512
Trying again. Right block this time.
Scans #8--14 are i0800x0064--4096
All scans ran OK. Levels looked OK except for known issues in i0800x0064 mode.
Submitting
CoherentCalTests
with 1400 MHz IF module filter
Scans #15--21 are c0800x0064--4096
All scans ran OK
Submitting
IncoherentCalTests
with 950 MHz IF module filter
Scans #22--28 are i0800x0064--4096
Scans #27 and #28 didn't seem to record data, but no errors. Hmm. Didn't catch this at run time.
Submitting
CoherentCalTests
with 950 MHz IF module filter
Scans #29--35 are c0800x0064--4096
All scans ran OK
Restored IF module filter settings for all modes to default.
Note: Turret was being rotated during scans 31 and 32.
Session ends at 16:03
Conclusions
Data collected successfully. Will analyze offline.
Should check modes i0800x2048 and i0800x4096 again.
