[Test-Equipment] HP 8552

[Mark Donaldson]

I have 2 HP-8552 spectrum analyzer IF sections that do
not provide an auto sweep output anymore. The manual
scan mode works somewhat, it will move the trace on
the far right side of the 141T display. This problem
is associated with the 8552 not the 141T mainframe
however it is possible that the IF section was damaged
by a 141T mainframe that had power supply issues.
Before I dig into this I was hoping somebody else has
been down this road and knows which part was likely to
have vented its smoke to cause what I am seeing.
