R&S FSH6 Repair and Advice Needed
« on: March 20, 2023, 04:47:45 pm »
I picked up a Rohde & Schwarz FSH6 that reportedly had a problem with the front end attenuator chip. When I opened the RF section

I saw bodge wires in the attenuator section over the top of what I believe to be the Macom 6GHz attenuator chip.

Anyone in the group that has a FSH6 ever seen anything like this? It just does not look to me something that R&S would do. So

before I go any farther and attempt to change the chip I thought I would ask here if anyone (perhaps a tech that works on these) has seen

anything like this before.

I believe that this is the attenuator chip:
