TGBT14A_912_65 - Continued Bank to Bank Discrepancy Investigations

Experimental Setup

Jeremy Darling tests

• Start at 9:00am
• Jason has hooked up the noise source to E,F,G,H again
• Ray is modifying Manager so that filtersnap_nogain gets captured properly.
• Run tests through Astrid so we can get everything configured correctly.
• Have to use L-band receiver, since they are doing a PF feed change.
• Ray fixes Manager, but still needs to fix up the effects of the bit pattern, so start with Jeremy Darlings script
• Copy to jdarling_K3_twowin. Configures ok. Steve explains how wideband mode works.
• Run jdarling_K3_twowin, scans 1 & 2
• Try switching to SubBeamNod:

SubBeamNod(src,scanDuration=20,beamName="MR12",nodLength=4)

• Validates ok, but get error:

[15:05:56] <type 'exceptions.ValueError'> need more than 1 value to unpack

• Move On from this, to noise source tests

Noise Source Tests

• Run Archivist
• Mode 4: Run bank_gain_mode_4kfpa - configures banks E,F,G,H
• Run checkLinearityBalance - just one scan
• Scan 3 - noise source at 0dB
• Discover that filtersnap_nogain sampler is not working properly - Ray fixes this.
• Stop for now.
