It turns out they are 50 Ohm SMBs.
Interestingly SMBs have become a lot more common (and cheaper) recently
because of GPS and wireless networking and extension cables and adapters
are now readily available on eBay.

Gentlemen,
I have two HP 8443 tracking generators, one is an "A" model with the
counter and one is a "B" model without the counter. Both use SMB
connectors on the coaxes that interconnect the individual PC board
assemblies.
