Teardown, Repair & Analysis of a Rohde & Schwarz FSH3 3.0GHz Spectrum Analyzer
<< < (10/10)
tonyM:
SMD parts with marking "534" are SPDT switches up to 6GHz.
In order to check if next sections are operational, you can bypass the input secton (Attenuator + Amplifier) by removing its first and its last SPDT switches, and soldering thin semi-rigid coaxial cable:
tonyM:
Only attenuator by-pass (by the same way it is originally done in TSMU-ver.2):

I realize that it has been a while but I would love to see the FSH6 even though I think I know how it works. I do have both a FSH3 and a FSH6 both with blown attenuator chips. It's been a while but I think that the one in the FSH3 that I have is a SOIC packaged part but I don't remember the part number. I think it was made by Macom.

After I get my E4407B fully squared away perhaps I'll work on the two FSH's assuming I can find the attenuator chip for the FSH3.

Thanks!
