ECR for Moving the 79.2MHz Doubler to ISC-R4

Document #:
Document type:
E - Engineering documents
Other Versions:
Move the doubler which drives the ALS fiber distribution box from rack ISC-R1 to ISC-R4. This reduces the electronics crosstalk between this unit and the PSL VCO. We will also used a different RF patch panel in ISC-R2. The RF power levels have been re-measured, possibly requiring to change the attenuator at the ALS fiber distribution chassis input. This is integration tracking issue 714.
