skrf.calibration.calibration.Calibration¶

class
skrf.calibration.calibration.
Calibration
(measured, ideals, sloppy_input=False, is_reciprocal=True, name=None, self_calibration=False, *args, **kwargs)[source]¶ Base class for all Calibration objects.
This class implements the common mechanisms for all calibration algorithms. Specific calibration algorithms should inheret this class and overide the methods:
The family of properties prefixed coefs and coefs..ntwks returns error coefficients. If the property coefs is accessed and empty, then
Calibration.run()
is called.
