Hi,
I'm having problem with an old HP8563E, a broken analyzer I got for free and I would like to have it at home for my hamradio experiements.
The unit shows a couple of errors, 355, 317, 319, 356, 335 etc.
It looks as there is a fault on the A15-board (maybe) somewhere around the "offset lock loop". Several of the signals mentioned in the "Service Guide" is not right, but it's nearly impossible to follow this without a schematic.
First, have anybody had this errors and what was wrong?
Second, does anybody have the A15-schematic as a pdf? Best would of course to have a CLIP for the HP8563E, but I have not found this on the net.
Regards
Jens, SM7OVK

My analyzer works most of the time, but I have got a new problem now. I sometimes get IDCALOSC error 550. I can run the analyzer several hours and suddenly I get this problem - so I think this is a new problem not related to the old.

I also found a bad connection in the SMB-connector at A15-J305. (The shield is badly connected.) This clearly, intermittent, decreased the value at A15-J702 from -8dBm to about -10dBm, together with several errors. This is hopefully some help for others.

thanks for info. Yes I have been in contact with Dave and he's been very helpful, but his CLIP was much newer than my instrument.
