skrf.calibration.calibration.TwoPortOnePath¶
 class skrf.calibration.calibration.TwoPortOnePath(measured, ideals, n_thrus=None, source_port=1, *args, **kwargs)[source]¶
Two Port One Path Calibration (aka poor man’s TwelveTerm).
Provides full error correction on a switchless three receiver system, i.e. you can only measure the waves a1,b1,and b2. Given this architecture, the DUT must be flipped and measured twice to be fully corrected.
To allow for this, the apply_cal method takes a tuple of measurements in the order (forward,reverse), and creates a composite measurement that is correctable.
