Data accuracy enhancement
Measurement calibration	significantly reduces measurement uncertainty due to errors caused by system directivity, source and load match, tracking and crosstalk. Full 2-port, calibration removes all the systematic errors for the related test ports to obtain the most accurate measurements.
Response calibration	Simultaneous magnitude and phase correction of frequency response errors for either reflection or transmission measurements.
Response calibration and isolation	Compensates for frequency response and crosstalk errors of transmission measurements, and frequency response and directivity errors of reflection measurements.

Full 2-port calibration	Compensates for directivity, source match, reflection tracking, load match, transmission tracking and crosstalk. Crosstalk calibration can be omitted.
Interpolated error correction	With any type of accuracy enhancement applied, interpolated mode recalculates the error coefficients when the test frequencies are changed. The number of points can be increased or decreased and the start/stop frequencies can be changed.
Reference port extension	Redefine the measurement plane from the plane where the calibration was done.
