You can measure the frequency, power and phase of the DUT along the time axis using Transient Measurement.
The E5052B's transient measurement has Wide-Narrow band mode and Narrow-Narrow band mode. The Wide-Narrow mode has four measurement trace screens to perform transient measurement of frequency, power and phase. The Narrow-Narrow mode has six measurement trace screens to perform transient 2 channel measurement of frequency, power and phase.
You can use each trace screen to measure the variation in frequency, power or phase after you have changed the output settings of the DUT.
The following sections describes the basic measurement method of the variations in the DUT’s frequency, power and phase by using the E5052B’s transient measurement window. This section describes the following topics about Transient Measurement:
