[evlatests] New Block Diagrams

[Jim Jackson]

I have posted a set of new block diagrams on the boards in the hallway 
outside Rob's office. Please check them over for errors and mark them up as 
needed. We'll run them through the CCB for approval when we do the project 
book chapters then officially release them.

Most changes correct mistakes, update power levels or add detail.  The only 
systematic change is in the connection of the 2-4 GHz baseband signals 
between the T304's and the DTS modules.  This reflects changes outlined by 
Barry in a message he sent last summer regarding having the two sample 
streams from a deformatter board being a polarization pair rather than the 
same IF channel. I had intended to change this earlier but it somehow 
slipped through the cracks.  There was some concern about isolation but I 
think Mike Revnell convinced us that there isn't a problem.   The change 
may already be on some diagrams that were printed for various people by 
Kathy Long in January or February.

Cheers,
Jim
