Today we measured the OLTF of the ISS inner loop and the PMC. This was done in response to LLO's recent measurement of the same documented here. Peter has all the TF data and will post it as a comment to this report. For the ISS inner loop, the gain was changed from 6dB to 16dB in the last couple of days, so we measured the TF at 6dB and at 16dB of gain to see how the increased gain changed things. For the PMC we ended up increasing the gain to 22dB (up from 18dB). This brought the UGF to ~7.5 kHz, closer to what we expect from E1200385.
I also had a chance to turn off the ISS without disturbing anything else and calibrate the 2 PDs discussed in alog 20043, and therefore complete the work in WP 5391. The new gain values for the these PDs are as follows:
