They are 2.92mm. The easiest thing to get is 2.92mm to SMA adapters, but
they are quite pricey at about $100 each.
You can order 2.92mm to *.* test port cables, but, again, expect to pay
quite a bit. Sometimes you see them on ebay for about $250-$300 each for
2.92mm to N or SMA.
I don't know what connectors these, as I don't have one, but I was lead to
believe by someone else they are 2.4 mm. If 2.4 mm as the author states, then
they will not mate to SMA. But if 2.92 mm they will mate to SMA. But of course
they wont have the performance. Also 2.92 mm is very fragile - much more so than
2.4 or 3.5 mm.
One of my VNAs has 3.5 mm NMD connectors on it. I managed to pick up a pair of
adapters to N for about $150, and much the same for adapters to 3.5 mm. I do
also have the proper test port cables, but they are serious money.
Sure you see NMD adapters on eBay for stupid money, but it is not hard to buy
them at a lot less. Many of the people asking $500 will probably take $100-$200
for them if you ask.

I just got hold of a 70820A microwave transition analyzer, and need either
cables or adaptors for the two RF ports. As I understand it, these are
APC-2.4 connectors, also known as NMD 2.4mm? Is that correct, two names for
the same connector, or is there some difference?
I just tried to find some adaptors, a quick look on ePay, one adaptor is
coming up at around $500 US, so I'd be spending more on the adaptors than I
paid for the whole unit. Anyone know of a more affordable source? I really
only want to go up to 26.5GHz, and don't really care about the perfomance
any higher.
