TRL  calibration verification

Question asked by CardiffUniversity on Aug 31, 2018


I am trying to verify the TRL calibration 

I used short standard from the Agilent which is not been used during my TRL calibration,

The result shows me the the value is rotating around the smith chart for freuency range from 1-6 GHz. 

Is that some thingright ?

I wish if could answer me and if it is not right waht is your sucgestion to check the calibration.

The attached graph is what I have got 


Many Thanks
