Persistent spectrum measurement

channel limit table. See “
Setting limit " for details.
Persistent spectrogram
The Persistent Spectrogram is particularly useful when attempting to identify periodic or intermittent signals as it captures spectrum
activity over time and uses various colors to differentiate spectrum power levels. When the directional antenna is used to receive the
signal, you will see a change in the amplitude of the tracked signal as you change the direction of the antenna and see a change in
the Spectrogram colors. The source of the signal is in the direction that results in the highest signal strength.
