I bought a couple of miniVNA and both came with a male SOL kit.
now, whenever I want to measure a DUT, I need to use cables which are terminated with a male connector.
to calibrate the set up I need to use a barrel (double female) to connect the SOL connectors, but this way I increase the length of the cable by at least 1/2 of the length of the barrel!
maybe it's negligible using SMA connectors but with N connectors...I have a Radiall R161 705 barrel (I guess rated for 10GHz) which is 4,5 cm. long!

so, why do not use only female SOL kits?

thanks in advance for your answers!

VNA calibration kits are available with both male and female connectors - my company sells them.


Specifically an SMA kit.

Note the male and female standards.

You do need both, but depending on budget, people will make do with less. Our basic 7 GHz VNA calibration kit, with no options, costs about the same as your miniVNA.

thanks Dave,
I knew you make professional kits, but they are far too expensive for my poor wallet. :-(
