Does anyone have data / cal coefficients on this Times Microwave VNA 18GHz OSL cal kit, N-male model OE5108 ?
Or perhaps offer to measure the S-Parameters for me in Canada ?
I spoke with Times, they said the model is obsolete and they could not locate the data. Maybe they did not try hard.

What VNA did you want to use this kit with? I can measure it compared to a Maury Microwave 18 GHz N kit I have. I wish I could compare it to my ECAL but my N model only goes to 9 GHz(until I find a deal on an 18 GHz unit).

At the moment i have 6 GHz set: 8753C + S-Parameters Trst Set with a doubler.

As long as you're covering shipping we can give it a go if you want.
The goal would be to save the measured values for the kit in touchstone format. We would then load those files into Metas VNA Tools(or others) and calculate the best fit correction factors. This would end in proper cal correction values in a format the 8753 can be loaded with.
We can try doing it to 6 and 18 GHz. Depending on the performance of the kit it may or may not be possible to generate 18 GHz best fit correction values for HPAK equipment.
A new thread detailing the process would probably be fun.

Sure, I will send a PM to arrange the logistics.
Many thanks!
