The matching connector on a 1730 is a DB connector of some sort. You
have to replace the round plug. I do not have the pinout handy. It may
also be possible that the 1730 needs an option to support that
functionality. By the time those 'scopes came out, it may have not been
a standard feature anymore.

That plug is not needed for normal operation. The operator just needs to
know when to change sweep speeds for the various WFM selector functions.
