Abstract
A method is provided that determines a relative phase change of a local oscillator signal. A method of determining a relative phase change of a RF signal is also provided. Generally, the methods described ensure that the effect of a swept local oscillator frequency on the measurements can be identified, particularly quantified. Hence, the effect can be considered in the error correction model applied later such that the measurement equipment can be calibrated appropriately.
