Problem with SOL Calibration in AWR Design

Hi everyone, I got a problem with SOL (short-open-load) calibration testbench for matching network for power detector in AWR Design. I built 3 testbenches (short open and load to measure S11 parameter of cable TLine) and came up with output equations to exclude influence of cable to measurements.

But it didn't work properly, because calculated parameter S11 (GammaDetector) doesn't match original S11 parameter for power detector LTC5587. Can you help me find the problem?

Testbench short:


Testbench open:


Testbench load:


Output equations:


Results (the parameters should be identical:



Thank you!
