    • 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.
    • 矢量网络分析系统和测量使用偏移刺激信号以刺激被测试的平衡器件(DUT)以确定性能参数的方法。 该系统包括提供多个刺激信号的偏移刺激源和矢量网络分析器。 在频率和时变相位中的一个或两个中,至少一个刺激信号偏离多个的另一激励信号。 偏移刺激源包括分别提供偏移刺激信号的第一信号源和第二信号源。 测量的方法包括产生偏移刺激信号并将偏移刺激信号施加到DUT的平衡端口以刺激DUT。 性能参数由偏移刺激信号的测量和来自受激DUT的一个或多个响应信号确定。
