Subject: DAQ running with TRANS channels - strange peaks as we scan the laser frequency 

We now have DC transmission channels in the frames. I'll post the details soon, but here's a plot that shows the transmission through the cavity on the RF_DC channel and the ACAV ISS DC as we slowly ramp the ACAV_SLOWOUT (temperature control) at a rate of 5E-5V/s.

Note the strange shape of the transmission peaks.

The wide view allows us to see the cavity transmit the upper and lower sidebands. Look carefully at the TRANS_RF_DC curve.
