The sweep gen did not come with any cables. Just using a BNC cable hookup to the RF and injected into the IF circuit with signal and a ground alligator clips.

1X setting on scope probe out.

I have RF inject and demod out cables from the EICO that were aftermarket builds by an eBayer who builds probes for all kinds of vintage equipment and his stuff is highly rated as I bought probes for my Heathkit VTVM from him. The issue is the probes do not terminate in male BNC hookups. They are the old style with a central solder spot in the center of a phenolic with a screw in ground. I would need to cut them up and modify them to use them. Not opposed to that since the Eico didn't work well.
