Field or control Description
Spectrogram
Toggles the spectrogram traces on or off. The spectrogram display is useful for monitoring slowly-
changing RF phenomena. The x-axis represents frequency
, just like the typical spectrum display. The
y-axis represents time. Color indicates amplitude.
Spectrogram slices are generated by taking each spectrum and flipping it on its edge so that it is one
pixel row tall, and then assigning colors to each pixel based on the amplitude at that frequency with
the cold colors of blue and green representing low amplitude, and the hotter colors of yellow and red
indicating higher amplitude. Each new acquisition adds another slice at the bottom of the spectrogram,
and the history moves up one row.
