HIGH FREQUENCY ANALYSIS OF A DEVICE UNDER TEST |
摘要 |
Analyzing a device under test (“DUT”) at higher frequencies. A phase shifter varies the phase of a standing wave on a transmission line coupled to the DUT. The standing wave magnitude is sampled at each of the phase shifts and one or more DUT characteristics are determined as a function of the sampled magnitudes and phase shifts. Further aspects include a related phase shifter comprising a waveguide having a plurality of sub-resonant slots formed therein and having active elements for loading the slots to control the phase shift applied to the signal.
