This has been discussed on the HP/Agilent mailing list. Basically a
couple of people that work at Agilent, one of whom is
"caesarv at email.com" (yes email, not gmail), will give out options for
8753 for non-commercial use. Just send him your S/N. I know he also
did likewise for an older 8720 instrument (I think 8720C).

Although he can, he will NOT do it for PNAs. That is one advantage of
getting a used 8753/8720 over a used PNA!

Agilent offered to repair my 8720D a couple of years ago, and managed
to give me a quote via email as it was abundantly obvious what the
problem was - a damaged thread on a test port connector. The only
problem was they wanted to change the whole coupler, so it was going
to cost the US equivalent of around $5000. A mate of mine sorted out
the nick on the thread with a needle file!!!
