7.6 Spectrogram
7.6.1 Description
This function shows a graphical representation of the spectrum superimposed
over time of a channel or frequency selected by the user. During the
Spectrogram, maximum and minimum of several measures and time are
registered. This tool is especially useful to analyse the behaviour of a spectrum
over time, because sporadic and indeterminate anomalies can be detected.
