Set Frequency Markers
Frequency markers are set in the frequency graph as shown in Figure: Set Frequency Markers. When the time slider moves, either manually or when the spectrogram play button is pressed. The frequency markers retain the set frequency at the locations marked while the power changes during the sweep.
Set Frequency Markers
1. Marker 1: Position the mouse over a frequency region of interest in the frequency graph and perform a shift-click to set Marker 1 on that frequency on the graph. See Set Time Markers.
2. Marker 2: Position the mouse over a second frequency region of interest and perform a control-click to set Marker 2 on that frequency on the graph. See Set Time Markers.
3. Time Slider: Indicates the time position within the time spectrum of the sweep. The slider moves as the frequency sweep is performed. The slider can be repositioned manually to perform analysis of a specific bandwidth.
