In order to use the new REFLAIR_B, we have made the following changes:
PRCL | SRCL | MICH | |
RF27I/RF9I | −0.49 | −3.9 | |
RF135I/RF45I | 2.4 | ||
RF135Q/RF45Q |
|
The RF27I/RF9I measurement for SRCL is low SNR for some reason. [Edit, 2014-11-05: I think I must have taken the RF135Q/RF45Q measurement upside-down. I retook it today and got a magnitude of 2.0.]
By using these gain measurements to adjust the DRMI 1f matrix elements, we have tried to transition from DRMI 1f to DRMI 3f. Howver, so far it keeps dropping lock.
The demodulated 1f and 3f spectra (taken while DRMI is 1f locked) are attached (units are cts/rtHz).
Something funny is going on with the LSC_INPUT_MATRIX. The ramping is not correct, plus it loads without the user request (and it's not the guardian)...
I was almost able to transition PRCL from 1f to 3f with a ramp of 10 and gain of -6.0 in the 3f signal, but it started to mode hop and lost lock. We probably should have touched-up alignment before trying to transition.
