Haven't seen these for a while now.
I recall... even used...they were pricey... everyone "needed'' a TG.
And you need an external counter... to 1.8 GHz... which isn't cheap either.
AFAIK... nothing special about the cables... just 2 50 ohm 28.5 inch coax.
Manual is available on Tekwiki.
Another expensive option is a TR503, and a 49X or 279X
But of course, that's not a 7000 system.
IMO... not worth it... just for a scalar measurement.
You could try the "Test-Equipment-For-Sale-Wanted-or-Exchange" group.
