Is you analyzer an HP8754, with the transmission/reflection test set?
If so, I understand exactly the issue you're dealing with. *;-)

I think so, Tom. I can't be sure as it isn't within reach at present.
ISTR is was built in around 1978/9. It would be great to have it
working properly again. It has some fault in that it will only display
in one mode (It can't show polar/smith chart output for some reason.
However, I have all the service manuals and a ton of test gear and
whatnot so must get around to fixing it. Do you own one of these
beauties?
