Yesterday I installed a new whitening chassis (JGW-S1808664) which happens to have a whitening filter board. The old chassis (JGW-S1808109), which doesn't have the whitening filter board, remanined disconnected in the rack. I didn't remove it because a heavy DC power supply on top.
The current settings of the 32 bit dip switch boards are different to the ones reported in entry 9823 because the gain was saturating some of the QPD quandrant:
- Oplev tilt QPD: S1809024, No 50,
- Oplev length QPD: S1809021, No 47,
- The following switches are on in both boards: 3, 4, 11, 12, 19, 20, 27, 28. A letter B preceeds these numbers.
- The rest are of the switches are off.
- Just for the record, the transfer functions of the whitening filters have been measured. An example can be found at JGW-S1605071.
