Re: 8510C - calibration 3.5/sma

 

BTW, SMA (normally to 18 GHz), 3.5 mm (to 26.5 GHz), and 2.92 mm (K connector, to 40 GHz) are mechanically compatible.? 2.4 mm (to 50 GHz) and smaller will not mate with those 3 (long story about HPAK vs. Wiltron (now Anritsu) rivalry to blame).? IIRC, 1.85 mm (V connector, to 67 GHz) mates with 2.4 mm.? I'm not sure about the 1.0 mm (to 110 GHz) and the newer 1.35 mm (to 86 GHz) connectors.

I've also heard of the 0.9 mm and 0.8 mm connectors but not about anyone actually using them.? I can imagine how much those cost.? Last I knew, about 10 years ago, the 1.0 mm Southwest Microwave connectors were about $1000 apiece!

HTH.

When you perform a calibration, you need a short, open, load, and thru. It looks like you have pulled up all the standards all of the defined standards in that kit. Note that there are different connectors (3.5, 2.92, 2.4, 1.85, SMA ) listed in the labels column. Those are not all compatible with each other so not sure why they are listed. Cal Kit definitions are kind of arcane exercises.

Any ideas, what the red circled elements are for?
