(Dick, Daniel)
The readback of the  IMC/PSL VCO was flaky. Today, we concluded that the 3rd and 4th channel on the timing comparator/frequency counter do not work very well above 40 MHz. We put the PSL on the 5th channel and it now is reliable. We were also missing about 20 dB of signal. This turned out to be the splitter mounted to the patch panel in the LVEA which was operated in the wrong direction. Fixing this gave us a signal of about 3 Vpp.

A new medm screen with name ALS_CUST_FREQUENCIES.adl has been created which list all the VCO frequencies as well as linear combinations describing the various beat notes.
