There's a 4.3 MB file available from this link, I hope it helps:

It leads to this URL:

Then auto loads a downloader.

It's an EXE file so I'm not sure it can be trusted, take care.

I've got other places to search so let us know if it's any good or not and I'll have another search.

The output power amplifier or the step attenuator are probably faulty.
If you don't find the service manual of the PM5150, you could use the service manual of the PM5193.
It is possible that the output power amplifier and the step attenator are the same.

On an unrelated note, have you noticed that it emits a -10V 90ms long pulse from the output connector when you first power it on?  Mine does that.  Very annoying!  Surprised I can't find anything about this bug on the internet.  My firmware version is 1.11

I have the same ugly negative pulse on startup. You would think they would mute the output while this occurs.
Now that I am aware of this, I will ensure that I am not hooked to anything that can be harmed by this pulse (I have the same firmware version).
I was looking for a new fan, this one is far too noisy.
