# skrf.calibration.calibration.UnknownThru.__init__¶

UnknownThru.__init__(measured, ideals, *args, **kwargs)[source]

Initializer

Note that the thru standard must be last in both measured, and ideal lists. The ideal for the thru is only used to choose the sign of a square root. Thus, it only has to be have s21, s12 known within $$\pi$$ phase.

Parameters: measured (list/dict of Network objects) – Raw measurements of the calibration standards. The order must align with the ideals parameter ( or use sloppy_input) ideals (list/dict of Network objects) – Predicted ideal response of the calibration standards. The order must align with ideals list ( or use sloppy_input switch_terms (tuple of Network objects) – the pair of switch terms in the order (forward, reverse)
