If the graph was then flattened so each channel’s FFT power for that single1-second sweep was represented
only by a color (and not by a value on the y-axis), the graph could then appear as follows:
Figure 132 FFT Power Spectrogram Sample
The spectrum analysis Swept Spectrogram measures FFT power levels or duty cycle data each second, so after
every 1-second sweep, the newest data appears as a thin colored line on the bottom of the chart. Older data is
pushed up higher on the chart until it reaches the top of the spectrogram and ages out. The example below
shows the Swept Spectrogram chart after it has recorded over 300 seconds of FFT data.

Table 170 describes the parameters you can use to customize the Swept Spectrogram chart. Click the down
arrow in the upper right corner of this chart, then click the Options menu to access these configuration
settings. Once you have configured the desired parameters, click OK at the bottom of the Options menu to
save your settings and return to the spectrum dashboards.
