Result Summary
Result summaries provide the results of specific measurement functions in a table for
numerical evaluation. The contents of the result summary vary depending on the
selected measurement function. See the description of the individual measurement
functions for details.

Spectrogram
A spectrogram shows how the spectral density of a signal varies over time. The x-axis
shows the frequency or sweep time, the y-axis shows the measurement time. A third
dimension, the power level, is indicated by different colors. Thus you can see how the
strength of the signal varies over time for different frequencies.
The spectrogram display consists of two diagrams: the standard spectrum result dis-
play (upper diagram) and the spectrogram result display (lower diagram).
For details see Chapter 6.10.2.1, "Working with Spectrograms" , on page 404.

6.2.3 Power Sweep Measurements
For a power sweep measurement, the internal generator signal remains at a fixed fre-
quency, but increases its power level within a specified range over time. The default
