TGBT15A_915_92 (cont.) - Test Stokes U and V with new VEGAS bof file

Goals

• Test behavior of Stokes U and V data with a new BOF file that uses registers in place of delay elements. Will also try to collect more ADC snap block data.

Details

• Switched VEGAS to pulsar branch
• Will use 00-CoherentModeArtifactTesting in c0800x0512 mode (this is the mode the BOF file was built for).
• Taking one scan with current BOF file (c0800x0512_fft_ovf_01_x14_7_2017_Feb_16_1132.bof) for comparison
  • SB submitted at 14:13
  • Scan is #8
  • SB ended at 14:14
  • Data look good except for phase wrapping, as expected
• Switching to test BOF file (c0800x0512_x14_7_rtd_2017_Mar_22_1107.bof)
  • SB submitted at 14:24
  • Scan is #9
  • SB ended at 14:25
  • No obvious changes in U/V data
• Trying to collect some adc snap blocks using Ray's filtersnap.py script
  • Got 300 snaps * Switched to release mode at 15:19 * Taking verification scan
  • Using CheckMode1 scheduling block
  • SB submitted at 15:25
  • Scan is #1 (Rob reset scan coordinator in between)
  • SB finished at 15:26
  • Data look good
