![]() Over time, this spectral view will approximate the steady-state RF energy signature of a given environment. Signal strengths that occur most often are 'redish' in color. A signal strength with a relatively low occurrence is 'blueish' in color, whereas increasingly brighter colors are used for signal strengths that occur more frequently. The power of the signal strength in dBm is shown across the frequency span. The 'Topographic Map' chart shows accumulated RF energy as a function of frequency. This feature provides a quick glance back into the sweep history to identify aberrations or fluctuation in frequency levels. As signal levels for specific frequencies or frequency ranges increase and decrease, the waterfall map varies its colors. It provides a color-based visualization of the RF level and activity over time. The 'Waterfall History' view is also known as a "heatmap" graph. Spectrum Trace ViewĬontinuously scans and samples the signal strength (dBm) of RF transmissions within the specified frequency range.
