RickS, Darkhan,
Yesterday, Jan 5, 2016, we took Pcal end-station calibration measurements at EX using WS1 calibration standard. The measurement procedure is described in T1500063.
Rough numbers from dataviewer and GPS times were noted in the attached scan (blank form is taken from T1500062).
A generated report (comparison with previous measurements) was uploaded to DCC T1500129-v3.
At first when we started the measurements we found out that laser power in PcalX is modulated through Pcal hardware injection channels H1:CAL-PINJX_*, we had to restart the measurements after tuning off these excitations.
At first we used CAL_INJ_CONTROL medm screen to turn off injections.
When we found out that some injections are still going into PCALX, we looked into H1:CAL-PINJX_* filters using auto-generated medm screens in
/opt/rtcds/lho/h1/medm/h1calex/H1CALEX_PINJX_*.adl
We switched off outputs from these filters before taking our measurements and put them back on afterwards.
Jeff pointed out that going to /opt/rtcds/lho/h1/medm/h1calex/H1CALEX_PINJX_*.adl is not necessary, there's a MEDM screen under Sitemap -> CAL -> PINJX that gives an access to Pcal hardware injection switches.
