Spectrogram Display
The Spectrogram is a display with the vertical axis (time) composed of successive spectral displays, each
having the amplitude represented by color or intensity. The horizontal axis represents frequency. The most
recently acquired spectrum results are added to the bottom of the spectrogram. The addition of a new
spectrum can occur at the fastest rate that new spectra can be plotted, or, if you choose, new spectra can be
added at a timed rate. The spectrogram view is well-suited to displaying long-term trends of spectral data.
The maximum number of lines that can be displayed in a spectrogram is 125,000.
The spectrogram can also be displayed in a 3-D waterfall format. In the 3-D waterfall format, the
spectrogram displays the time axis along a simulated Z-axis.
NOTE.
Spectrogram data is shared with the Spectrum display. There is no linkage between DPX and
Spectrogram.
