I have pulled the RF distribution box out of the rack, so I can look at it, and modify it to have 2 110 MHz spigots. I'm going to make the mods as in elog 9072.
Before I pulled the distribution box, I turned off the RF Generation Box, so don't be surprised that the MC will not lock. I have terminated the cables that bring the 11 and 55 MHz signals from the generation box to the distribution box, so if someone does turn on the generation box, there won't be bad reflections.
To get the box out, in addition to unplugging all of the cables that go to the distribution box, I had to disconnect 2 of the ADC ribbon cables from the top row of RFPD demod / whitening / ADC boards, since they were in the way. Everything is labeled, so it should be easy to put back together.
Note to Future Jenne: Past Jenne put the screws needed for those ADC cables and to hold the box in the rack, in the plastic box that is on the floor in front of the LSC rack.
Also, I measured the 110 MHz port before I pulled the board, so I would know what my "before" looked like. I was using the 300MHz 'scope's measurement functions, so these are in volts, not dBm. Amplitude = 1.33V, RMS = 456 mV, freq = 109.4-111.9 MHz
