Abstract
A rectangle marker on a display of a signal analyzer simultaneously designates time and frequency intervals of data from a signal under test for analysis. The data of the signal under test is displayed as a graph having time and frequency axes. Sub-graphs show data designated by the rectangle marker as processed in the time domain, frequency domain and modulation domain. The resulting display provides an overview of the signal under test and simultaneously provides displays of measurements and analyzes for a designated portion of the data.
