content: I'm looking for a few scraps of Belden 9222 Triaxial cable to test fit to some Triaxial connectors before I commit to a full roll.If anyone has a few short offcuts that they can throw in an envelope and post to Japan, please let me know.Thanks!

content: If you get desperate then Farnell/Newark sell by the meter (would likely need someone to buy in the US or UK then post it), or you could try and find a Pomona pre-made triax cable (Pomona state what triax is used, and it's normally Belden 9222 from what I've seen).

content: Newark in USA only sells it in 100-foot rolls at $224.56 for one roll ($2.25 per foot), but UK stock can be had for $4.00 per meter ($1.22 per foot) through US Newark, which is half the price per foot of the rolls.

content: I've managed to source some offcuts now from another member. Thanks all!If it fits my connectors, I can get 30m (100') rolls from RS Japan for a reasonable price. I just didn't want to buy a whole roll to find it didn't fit....

content: Quote from: TimFox on July 29, 2021, 03:21:35 pmIt gets sillier when you have a look at Farnell (same company as Newark), who sell the same thing in the UK for twice what the _UK STOCK_ costs from Newark.Anyway, good to hear of your success. Just a heads up that if you're using it in a sensitive application where the cable may be flexed, then might be worth checking whether cable movement induces too much noise - the belden cable isn't of the "low noise" type.Also, if you've got a lead on cheap triaxial connectors then please share!

Now they have three variants available. JY75-2, JY75-1.5, JY75-3If they did when I ordered, I can't recall which one I got. Don't know what's the difference.

content: Thanks, good to know for the future. At a guess I'd say the difference is likely cable entry size.I've still got a couple left of these:https://www.ebay.co.uk/itm/263311367354(were $15 per 2 pcs, I bought 8 in total)If any more come up then I can confirm that they're usable (though not perfect) for triax as well as the suggested twinax.

content: These are the connectors I plan to use pending cable fitment tests. Apparently this is the same company that were used for some HP gear (I suspect the Yokogawa/HP gear mainly)https://www.monotaro.com/p/8787/9626/Does anyone have suggestions for low noise triaxial cable? I'll be using these cables for my 4145A semiconductor paramater analyzer, and my 4140B pA meter, so they might benefit from the better cable.

content: I built up a cable using HUBER+SUHNER G_02330_HT low-noise triax from mouser. Worked fine but doesn't feel as rugged as the other Trompeter cables I have, and the center conductor is a single solid core, rather than stranded.
