FWIW:
The guts of a BNC/TNC is very similar if not identical to a type N,
which is good for at least 12.4 GHz. The Agilent 13 GHz scopes
have "precision" (IE tight fitting) BNC connectors on the probes.
All of which of course doesn't mean the Asian BNC's you bought
at the hamfest are any good.

There is a very significant difference between the N and the BNC
construction with regards to what is the insulator in the transition
section between the male and female connector: With the BNC (and TNC)
connector(s), the space is filled with an interdigitated plastic
dielectric. With the N, the space is filled with air.
