When we study about calibration, usually 12 error terms 8 error term are found along with various method like TRL , LRL , SOLT etc.

When we see any two port VNA we have a1,a2,b1,b2, r1, r2 . we need to calibrate using these terms only.

1. How can we find calibration parameters from the above 4 parameters (a1,b1, etc) like ESR,ESF ,ELF etc?

2. What minimum parameters I need to use from 12 error terms for manual calibration?#
