The Sampling Oscilloscope as a Microwave Instrument
Dylan F. Williams, Paul D. Hale, Catherine A. Remley
Many modern high-speed oscilloscopes are well suited for precise microwave waveform, modulated-signal, and nonlinear measurements. These oscilloscopes have bandwidths of up to 100 GHz and are available with nominally 50 ? input impedances. Like their low-frequency counterparts, these oscilloscopes are flexible, easy to use, and relatively inexpensive. This makes them ideal for testing a wide variety of microwave sources and other microwave components.
