sorry but the one on keysight has all the chapters including servicing and adjustment and also schematics?
this is the one? I have used to repair multiple of these units in the past...
one time however, in one of the signature tables (dont remember which one) there was a signal (clock?) that did not exist on the
logic board that I was repairing but it was in the schematics. I managed to create that signal using a spare gate?
in one of the chips on the board and a bit of wiring.?
