[Sbs_gems] [EXTERNAL] UV GEM 3 slot back plane fixes - positive results!

[Anuruddha Rathnayake]

Dear All,

We have tested both the fixes for 3 slot backplanes and finally got
positive results.

   1. Fix one is the termination of trigger and clock lines in the 3 slot
   backplane - see the attached picture "3slot_back_pane_fix.jpg"
   2. Fix two is the analog channel "shifter" - see "shifter_1.jpg" and
   "shifter_2.jpg". Ben found that the boards we got made had the analog
   channels incorrectly routed. Therefore, Armen and him found a fix for that
   by reversing the direction of the HDMI connector.

I have attached the MPDLIbTest results and the raw APV frames of the first
backplane we got fixed to test out the fixes. Both the tests give expected
results now. I gave the remaining 15, 3 slot backplanes to Armen and he
gave an estimation of next week Tuesday-Wednesday for the completion of the
job.

Best,
Anu
