VEGAS Team Meeting
Attendees: Richard, Paul, Amanda, Anish, Marty
Agenda:
- progress on ADC calibration
- resolution of blanking time issues
- Progress on current issues
- use of non-maintenance time for VEGAS testing
Meeting notes:
- progress on ADC calibration
- John, Randy, & Jason spent some time running Hong's python script, which automatically performs the ADC calibration. The SRBS roach2 was used for these tests. The roach2 was first power-cycled to reset the ADC registers to default values. The calibration process appeared to reduce the spurs from ~-35dBm to ~-70dBm!
- Some time was spent perusing the code to figure out where & how the values are sent to the roach2. This info will be passed to Ray for future implementation in the M&C software.
- Jason emailed a few requests to Hong for features to add to the scripts, such as adding titles to the plots, scaling the x-axes in frequency, and an option to auto-save the plots. She has already made these changes but they haven't been tested by NRAO folks. That should happen this week.
- It would probably be worthwhile to do this procedure on all of the vegas roach2's sometime soon.
- resolution of blanking time issues
- Blanking time discussions. I've been working on a page trying to summarize the discussions thus far, and lay out what needs to be updated.
- Progress on current issues - See CICADAGreenBankSpectrometerCurrentIssues
- use of non-maintenance time for VEGAS testing
- We need more maintenance time than is available on maintenance days.
- There seem to be few trained observers on VEGAS so there should be a way
- Discuss during Quarterly Planning meeting
Other
- Paul to take request back to SDD team to better document releases now that multiple folks are releasing software
- Please make sure to properly code your timesheets for the current time period and going forward.
- Software engineers should be using a GBT ops software CM&E account
Account 893252
- Electronic engineers should be using a GBT ops electronics CM&E account
Account 432510
- Commissioning activities should be getting charged to hardware support and testing (432510)
Account 432510
- scientists assisting with shared-risk commissioning should be charging an observer support account.
432540 for the most part. Accounts 142023 (GB-based staff) and 142013 (CV-based staff) for when you are helping with overarching observing support (not problem solving, VEGAS specific)
