Displaying a spectrogram
In addition to the standard "level versus frequency" spectrum display, the R&S
FSV/A
also provides a spectrogram display of the measured data. A spectrogram shows how
the spectral density of a signal varies over time. The x-axis shows the frequency, the y-
axis shows the time. A third dimension, the power level, is indicated by different colors.
Thus you can see how the strength of the signal varies over time for different frequen-
cies.
