Patent ID: 7646205

Claim:
A method of using a network analyzer and a test controller to measure at least one scattering parameter (S-parameter) of a device that rapidly switches through a plurality of states, said method comprising the steps of: (a) sending a first trigger from the test controller to the analyzer; (b) performing a frequency sweep of the device by the analyzer when the analyzer receives the first trigger from the test controller, said frequency sweep having substantially the same start and stop frequency; (c) measuring by the analyzer, at least one S-parameter of the device; (d) sending a second trigger from the analyzer to the test controller, said second trigger causing the test controller to step the device to a next state in a predefined sequence of states, if a next state exists; and (e) iteratively repeating steps (a) through (d) until S-parameters have been measured for all of the states in the predetermined sequence of states.
