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. |
| coefs | coefs: a dictionary holding the calibration coefficients |
| error_ntwk | a Network type which represents the error network being |
| frequency | frequency object for the calibration |
| 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 |
