Kiwamu, Daniel, (WP7066, ECR:E1700127-v1)
We modified the ASC front end model in order to accommodate lock-in oscillators which will be used for commissioning the new AS72 WFSs (37042). The conceptual design is summarized in T1700324. Additionally, we removed the parts that were for the AS90 WFSs because (A) we had not been using them and (B) we will take over the same electronics and ADCs for the AS72 WFSs. The below are the model files that were modified today:
- asc/common/ASC_MASTER.mdl
- isc/common/WFS.mdl (where we added new library blocks)
- sys/common/PLL_MASTER.mdl (where we added new library blocks)
They are checked into SVN. Note that Livingston is not using ASC_MASTER these days. The attached screenshots show the new components in the ASC model. As stated in the ECR, we are adding twelve new DQ channels as follows.
- ASC-AS_(A|B)_RF72_(I|Q)_(PIT|YAW)_OUT (2048 Hz)
- ASC-AS_(A|B)_RF72_(I|Q)_SUM_OUT (2048 Hz)
Also, we removed the following four DQ channels that needed to go out since we took out the AS90 system:
- ASC-AS_(A|B)_RF90_(PIT|YAW)_OUT
I was able to compile the model without any error messages. The model is ready to install tomorrow during the maintenance period.
