Importing more needed infrastructure from LLO (LLO:64213) I've updated some library parts which take in the following changes to the corner-station CAL-CS model (h1calcs):
- Adding more infrastructure to be able to demodulate the new(ish) PCALX systematic error lines,
- Adding a few more EPICs records that represent corrections to PCAL, DARM, and DELTAL channels, after finding a new level of understanding about correction factors, delays, and advances from LHO:68880
- Along the way, this brings in a (what will be unused here at LHO) alternative method to subtract all the calibration lines from DELTAL_EXTERNAL
- Adding an EPICs record that represents how the ratio between PCALX and PCALY should be corrected for known / expected differences
- And with all the extra demodulation infrastructure, it means we need to re-introduce the setting that adds one 16 kHz clock cycle delay before sending channels out over RFM (the rfm_delay=1) into the cdsParams parameter block to allow for the extra time to compute what should be sent from the corner station to the end station (which is also unused her at LHO).
Attached are a ton of "before" vs. "after" screenshots. I'll walk through the meaning of these changes in detail in the comments in the fullness of time.
For now, the message that I've imported the changes to
/opt/rtcds/userapps/release/cal/common/models/
CAL_CS_MASTER.mdl
CAL_LINE_MONITOR_MASTER.mdl
and committed the rfm_delay=1 parameter add to the
/opt/rtcds/userapps/release/cal/h1/models/
h1calcs.mdl
to the svn repo, and tested that the h1calcs model successfully builds.
