CLF loop closed!

Daniel, Nutsinee

It seemed that we weren't in dual resonance but somehow still got some down conversion through. About -60dB of 6 MHz beat note was visible from the RF mon (this number has already taken 23dB attenuation into account). The UGF was only at ~80Hz but a lock is a lock! We will try again after we tune the oven temperature for dual resonance tomorrow -- expecting a factor of 100 more signal once this is achieved. The VCXO should have 100kHz range. The transfer function was a bit noisy due to an on-going work on the SQZT6
