Looking for R&S HM7042 Service manual
« on: April 11, 2021, 12:32:16 pm »
I'm looking for a service manual/schematics for HM7042. Searched a bit on Google and found a ton of Russian sketchy sites which isn't legit.

Got some overshoot issue on the device i'm trying to repair, pretty known for those to get overshoot issues after a long time of service(+20 years)
Pulled out most of the caps on the AC-DC board and checked them on LCR meter only to see them being within spec.
I found the HM7042-5 schematic but they have done some major changes on it since then so much of the circuit is different.

Hopefully somebody can share it.
