Abstract
Methods and systems for measuring the reflection coefficient of a network are disclosed. The methods and systems measure the reflection coefficient by exciting a device under test with a driving signal. The driving signal incident on the device under test is measured and the source providing the driving signal is removed thereafter. A signal reflected from the device under test is sampled at a sample rate that may differ from the frequency of the driving signal. The reflection coefficient of the device under test is calculated by dividing the measured level of the reflected signal by the measured level of the driving signal.
