Title: Rohde & Schwarz HMC8043 PSU Service manual / Schematic
Post by: Neuro on October 01, 2023, 11:00:20 am

Hello and thank you for providing such a great forum! 
Lots of useful information throughout the whole site.

I've got a brocken Rohde & Schwarz HMC8043 PSU, which I'm trying to repair.
My search in Internet, trying to find a service manual gave nothing.
So may be, someone knows, where can I get a schematic diagram of this PSU?

TIA for any replies and have a great day!

I'm looking for one too. I've got a (half )broken HMC8042, only ch1 is working. ch2 is dead and I've traced it to a low on the enable pin on the lm5001. I can't trace where it's coming from since the signal disappears into a middle layer....

R&S and  NO Service manual / Schematic    :palm: :palm:

However, HMC8043 has been repaired and is close to being scrapped.
