E - Engineering documents
Document tree for the delay line phase shifter. These phase shifters are used in the LO line for I/Q demodulators that are used in analog servos (where the I/Q phase shifting cannot be done digitally). Specifically:
- Input mode cleaner servo
- Common mode servo
- ALS end station PDH cavity locking (uses a CM servo)
