1. A method of calibrating a network analysis system comprising a device measurement path located between a first receiver and a second receiver, the method comprising:
- determining a phase response of the first receiver independent of the second receiver;
determining a phase response of the second receiver;
determining a phase tracking response from the phase response of the first receiver and the phase response of the second receiver to establish a calibration of the device measurement path;
measuring a raw phase response of a device using the first receiver; and
modifying the raw phase response according to an actual phase response of the device, wherein modifying the raw phase response comprises dividing the raw phase response by the actual phase response of the device.

Abstract
A network analyzer comprises: a signal source configured to supply an input signal to a device, wherein the device is configured to generate a phase reference signal; a receiver configured to receive the phase reference signal from the device and to measure a phase response of the device according to the phase reference signal; and a calibration component configured to compare the measured phase response of the device with an actual phase response of the device to identify a tracking parameter for the receiver.
