No, I believe, you need to do TRL, LRM OR ALRM calibration to take into account
phase delay

Subject: [SI-LIST] Calibration VNA question
Hello All,
I am struggling to understand the calibration process of VNA. I am doing
open, short and Load calibration with calibration kit. I understand
that when calibration is done the measurement plane is set to the end of
the coaxial cable.
Here is my dilemma:
When we are doing calibration with a calibration kit , the actual
location of short , open and load point is at some delay from the end of
the coaxial cable ( I have attached coaxial cable which have SMA
termination ). Is that delay is already accounted in the calibration or
we have to do port extension to compensate for that delay ?
Thanks in advance for your suggestions and opinions.
Regards,
Navroop
