ECR for Adding Frequency Readbacks

Document #:

LIGO-E1400079-v1

Document type:

E - Engineering documents

Abstract:

During commissioning we are using an ifr RF frequency synthesizer to drive our main modulation frequency in the corner. Right now, we also use an ifr synthesizer in the end stations to explore the modulation frequency space. In contrast to our RF sources, we currently have no frequency readbacks for the ifr synthesizers.
