Dick, Kiwamu,

We measured the volts-frequency relation of the ALS DIFF VCO by closing the ALS diff VCO PLL. We will upload the data and results later.

In order to measure the VCO response, we discconnected the DIFF beatnote from the phase-frequency discriminator and temporarily hooked up an IFR 2023A to simulate a clean signal. After we finished the measurement, we reconnected the beatnote cable back to the phase-frequency discrminator.
