WP7162 Squeezer Install, ASC H/W and S/W changes
Daniel, Dave:
The 8th ADC and the 2nd DAC cards were removed from h1asc0's IO Chassis. Serial numbers are shown in the table below.
The CDS system was configured to no longer run the models h1sushtts and h1susauxasc0 on h1asc0, and to remove it from the DAQ.
The h1asc and h1ascimc models were modified to use the 1st DAC instead of the no-longer-present 2nd DAC. The details of this can be found in the DCC document:
https://dcc.ligo.org/LIGO-T1100472 page 9.
Because of the slight-but-not-zero chance that powering h1asc0 back on could Dolphin glitch the corner station SUS and SEI, we coordinated with Team-Vent for the optimum time to power h1asc0 back on. Jeff K gave permission for the power up and DAQ restart during the lunch hour. Consequently I powered up h1asc0 with no problems. Before restarting the DAQ I took the opportunity to modify h1pemcs to add filter modules in the input legs of the MAG_EBAY_LSCRACK Quadrature Sum circuit so Robert can perform AC coupling tests on the quad-sum signal. The DAQ restart went well. When I noticed that the EDCU was still RED, I found that h1ecatx1 had frozen at 06:30 this morning (Patrick restarted it).
| card | serial number |
| 16bit DAC 16AO16 | 110419-25 |
| 16bit DAC interface card | S1102283 |
| 16bit ADC 16AI64 | 110506-77 |
| 16bit ADC interface card | S1102495 |
To remove the models h1sushtts and h1susauxasc0 from CDS I followed my new wiki instruction page (checking for errors and omissions)
https://cdswiki.ligo-wa.caltech.edu/wiki/RemovingFrontEndModel
I have created a new CDS Overview MEDM screen called H1CDS_POST_O2_OVERVIEW_DETAIL_CUST.adl
On its first release it is identical to the O2 version except the models h1sushtts and h1susauxasc0 have been removed from h1asc0 (see attached).
