Learn something new every day! No, never saw those connectors, I
assume they are RF.

Engineers put lots of nasty things like that on the back of
subassemblies that blind-mate, like scope plug-ins. I bet they snicker
at the trouble they know techs will have repairing them.

This shows a 2-coax version of that connector on the IF section of a
spectrum analyzer like mine:

"J3 connector mates directly with the plug-in RF Section. Some care
is needed to avoid damaging this connector."

The RF section plugs into the top of it, then both together slide into
the main frame. Someone had spare plug-ins at the ham flea market a
few weeks ago and showed me how they go together. I guarantee you that
not every electronics company engineers the mechanicals like this as
well as HP and Tektronix.
