Meeting notes:

1. Status of internal RFI and OGP solution
   • Waiting for UCB
   • Solution:
     • Flagging for LBW modes - locations not as simply located as for HBW modes
     • Implementation details needed [Adam]
       • Joe can assist w/ details
     • MR 1 in preparation - solution
     • MR 2 in preparation - SDFITS changes
   • We can suspend weekly tests
2. Mode 10-19 hardware fix
   • Testing Tuesday
     • High channel mode fix (v.3)
     • Mode 4-19 Fixed bug in switching interpretation (data vs. phase state)
3. Baseline ringing (high frequency noise) in VEGAS data
   • Status of more stable and insulated cabling
     • Electronics is fabrication a couple higher quality cables to test
   • (hopefully) testing the S/N ration range of VEGAS with attenuation on Thursday
     • Determine sufficient S/N ratio to support use of 20dB attenuators to improve ripples
4. Integration time MR
   • Ray has drafted
   • Joe is checking
5. Top Hat -
   • change to abort scan upon occurrence
   • any update/occurrence? [No]
6. Test Time
   • Tuesday
     • Mode 10-19 hardware fix
   • Thursday
     • S/N ratio tests
7. Other
