[evlatests] IFs B & D

[Rob Long]

Hi Rick,

I see writeups for Ifs B& D regularly, but are we doing anything about 
the LUT attenuator values for these IFs?  This has been an ongoing issue 
and now with new default (and changing depending on the test) LO 
frequencies, I can watch the screens and see that the power levels at 
the T304 are not correct.  We are working on the downconverters to get 
all modules running with ALC capability, but it is not available yet. 
This means some tweaking of these B & D downconverters will be required 
frequently.
