Hi, I have ques. about calibration;

I am using 85056D economy calibration set, but when measuring short or open response I got linear phase varying between minus pi and pi. Magnitude responses was flat and zero dB.

I adjusted  port extensions to obtain a flat phase response with open load, and I obtained almost flat phase response. Then I measured short response, it was almost flat,

I measured both short and open responses with same calibration plane, I did not use any adaptor. Finally with port extension phase is flat, But  I still am wondering that this calibration is correct?
