Thank you to all who replied to my request for help. I now understand more
about the operation of this piece of test gear and also believe the solution
to my problem is more complex than I originally thought.
Given the investment in time, money, and effort it will take to acquire
and/or fabricate things like circuit board extenders and jumper cables with
those goofy (Yes I still think HP used "goofy" connectors, they aren't SMA,
SMB, SMC, or SM* anything) connectors on one end and BNC on the other, I
believe it might be more expeditious to find another 8443A I can purchase,
only after verification that it is working properly, than to attempt the
repair of mine.
I will do what trouble shooting I can without those items before writing
this one off.
