I have two signal generators with the same kind of output connector. I need an output cable. The female connector (on the generators) has threads on outside. The male connector (cable) has threads on the inside. One screws the connector (cable) onto the generator. The center conductor on cable and generator make contact with each other with a kind of flat solder point. One generator is a Precision Signal Generator series E-200-C. The other generator is a Precise Universal sine, square and pulse model 635. What cable do I need and where can I get one? It's probably coax with probe and ground clip.

These sound like old-style Canon or Amphenol microphone/audio connectors. They were popular in the 50s. My Heathkit Sig Generator also uses these. I replaced the connectors with BNC connectors. You can find a lot of standardized cables with BNC connectors. Most modern generators and scopes use BNC. You might find old Canon connectors at places that sell vintage audio or guitar amplifiers.

If you really want to continue to use the older style connectors, they are called Amphenol 75PCM types. You can get them from:

Good luck,

Switchcraft makes them as well, if you can find a Switchcraft dealer in your town.

How did you replace the Amphenol connectors with BNC connectors? Did you have to drill new holes?

Phil: you don't have to drill new holes to accomodate BNC jacks - the existing holes are the correct size.

I converted my old Eico equipment to BNC, which allows me to use various 'scope test leads that I have. I hung the old mic connector inside the cabinet in case somebody in the future wants to convert it back to original.

I didn't drill any new holes on my Heathkit SG-8. The existing holes work well. I don't think these old sig generators will ever have much collector value, so why not make them as useful as possible? BNC is really a major convenience and allows use of various cables and adapters... all of which are current and standard. Rich
