Teardown of the U2 amplitude assembly, which I suspect is faulty and causing the issue this unit has wit incorrect sensitivity and amplitude measurement above 500MHz.

[@Mark19960]

Hmmm. wonder if someone whacked too much power into the frontend and blew that bondwire off..
Interesting look inside of one of those modules.

[@TheDefpom]

Yeah, I need to find a new input unit, the diodes seem to be blown, haven't had much luck so far.

[@SoddingaboutSi]

Good try. Frustrating faults this small!
