Abstract
A vector network analysis system and a method of measuring use offset stimulus signals to stimulate a balanced device under test (DUT) to determine performance parameters. The system includes an offset stimulus source that provides a plurality of stimulus signals and a vector network analyzer. At least one stimulus signal is offset from another stimulus signal of the plurality in one or both of frequency and time-varying phase. The offset stimulus source includes a first signal source and a second signal source that respectively provides the offset stimulus signals. The method of measuring includes generating the offset stimulus signals and applying the offset stimulus signals to a balanced port of the DUT to stimulate the DUT. The performance parameters are determined from measurements of the offset stimulus signals and one or more response signals from the stimulated DUT.
