Abstract
A method for removing phase errors from RF signals generated by movement of the cable interconnecting a network analyzer and a device under test. The method includes the steps of measuring the phase difference between incident and reflected signals during calibration to establish a reference, measuring the phase difference between incident and reflected signals during device testing, comparing this result to the reference to generate an error signal from phase correction.
