HAMlab, Release 1.0

PEAK DETECTION

During the measurement, peak values of the signal spectrum are measured and shown on the “Peak Val-
ues” field. Peak values are max values of the signals spectrum regardless of the selected frequency range.
This peak finding prevents not seeing peak values which are outside the selected frequency span.

WATERFALL PLOTS

Waterfall plots are a different way of the signal spectrum representation where the color on the plot
defines the signal amplitude for a certain frequency. The waterfall plot is also useful when enabling the
representation of the signal spectrum in a time dependency.
