Display Spectrogram

This procedure explains how to display a spectrogram of a spectrum trace. The spectrogram is a
2D or 3D rendering of the historical data, up-to-256 spectra displayed in a vertically stacked
display. The spectrogram can be shifted/rotated on any of its two or three axes and can be
generated in colorized or monochrome versions to more easily visualize high-occurrence
samples.

1.

Set up the spectrum trace

.

2. Choose Type 2D or 3D and check View.

The spectrogram is drawn in a new grid above the spectrum trace.

3. Move the Spectrogram slider or touch the Right/Left Arrow buttons to increase or

decrease saturation level.

Saturation corresponds to how often a frequency occurs in a spectrum. The greater the
saturation, the more variation you will see in the spectrogram.
