calibration (skrf.calibration.calibration)

This module provides objects for VNA calibration. Specific algorithms inherit from the common base class Calibration.

Base Class

SDDLWeikle(measured, ideals, *args, **kwargs)	Short-Delay-Delay-Load (Oneport Calibration).
PHN(measured, ideals, *args, **kwargs)	Pair of Half Knowns (One Port self-calibration).

Two-port
