Figure 121 Simple Line Graph of FFT Power Data
Now, suppose that each channel’s FFT power level was also represented by a color that corresponded to that
specific FFT power level. In the example below, channel 12 has a FFT power level of -50 dBm, represented by
the color red. Channel 1 has a FFT power level of -85 dBm, represented by dark blue.

If the graph was then flattened so each channel’s FFT power for that single1-second sweep was represented
only by a color (and not by a value on the y-axis), the graph could then appear as follows:
