Added Intensity, Frequency, and 9 MHz Intensity Lines at around 74 Hz
Dan Brown, Craig We are injecting lines into the DARM spectrum as follows: Intensity: 76.4 and 3250 Hz Frequency: 74.7 and 4500 Hz 9 MHz AM: 72.3 Hz
The Frequency line made it impossible to lock :(
I disabled the common mode board excitation input, and we're back on track, almost locked. I still see a giganto line from the other 2 excitations however.
