It looks to me like a MIL-C-49142 style connector, however I'm not sure what the rated voltage of that style connector is.
Either way, Trompeter sells their 370 series that are essentially threaded BNC-size triax connectors that conform to the 49142 spec. I believe Trompeter is now absorbed into Cinch. Maybe something like the PL375. Digikey has some in stock that accept various cables. The datasheet drawings + calipers may be enough for you to confirm a match, or at least this might be a starting point for you. http://www.jrhelec.com/assets/images/manufacturers/cinch/catalogs/catalog.pdf https://www.digikey.com/products/en/connectors-interconnects/coaxial-connectors-rf/437?k=pl375 On Sat, 17 Feb 2018 at 12:32 Florian Teply <use...@teply.info> wrote: > Hi David, > > Am Sat, 17 Feb 2018 15:32:15 +0000 > schrieb "Dr. David Kirkby" <drkir...@kirkbymicrowave.co.uk>: > > > In order to use the meter, I would obviously need to be able to make > > connections to it. > > > > Is there anyone here that knows what the triaxial (tri-axial?) > > connector in the attached pictures ?
