skrf.calibration.calibration.Calibration

class skrf.calibration.calibration.Calibration(measured, ideals, type=None, is_reciprocal=False, name=None, sloppy_input=False, **kwargs)

An object to represent a VNA calibration instance.

A Calibration object is used to perform a calibration given a set meaurements and ideals responses. It can run a calibration, store results, and apply the results to calculate corrected measurements.

Attributes

Ts	T-matricies used for de-embeding, a two-port calibration.
caled_ntwk_sets	returns a NetworkSet for each caled_ntwk, based on their names
caled_ntwks	list of the calibrated, calibration standards.
calibration_algorithm_dict
coefs	coefs: a dictionary holding the calibration coefficients
error_ntwk	a Network type which represents the error network being
nports	the number of ports in the calibration
nstandards	number of ideal/measurement pairs in calibration
output_from_cal	a dictionary holding all of the output from the calibration
residual_ntwks	returns a the residuals for each calibration standard in the
residuals	if calibration is overdeteremined, this holds the residuals
type	string representing what type of calibration is to be

Methods

__init__	Calibration initializer.
apply_cal	apply the current calibration to a measurement.
apply_cal_to_all_in_dir	convience function to apply calibration to an entire directory
biased_error	estimate of biased error for overdetermined calibration with
func_per_standard
mean_residuals
plot_coefs_db	plot magnitude of the error coeficient dictionary
plot_errors	plot calibration error metrics for an over-determined calibration.
plot_residuals	plots a component of the residual errors on the Calibration-plane.
plot_residuals_db	see plot_residuals
plot_residuals_mag	see plot_residuals
plot_residuals_smith	see plot_residuals
plot_uncertainty_per_standard	Plots uncertainty associated with each calibration standard.
run	runs the calibration algorihtm.
total_error	estimate of total error for overdetermined calibration with
unbiased_error	estimate of unbiased error for overdetermined calibration with
uncertainty_per_standard	given that you have repeat-connections of single standard,
