I am planning to use adapter removal calibration for my measurement. one port is SMA and the other port is GSG on wafer. I have some questions.

1)Is the adapter removal calibration valid for this kind of measurement?
2)In the user manual. "the specified electrical length of the adapter A3 withing +/- 1/4 wavelenght for measurement frequency range" pp.6-41.  I have 2 options to use for the A3 adapter.. 1) sma m/m cable (1meter) + gsg probe + thru of calibration substrate 1) gsg probe + thru of calibration substrate. I would like to ask which option will do a better job.

I still don't have the DUT with different connectors yet. and I am currently exploring my calibration options.

Thank you very much for your time and attention.
