Abstract
A signal analyzer has a display with two regions. In a first region there is displayed a first waveform representing a signal. The first waveform is shown in two dimensions. One dimension represents signal amplitude and one dimension represents signal frequency. In a second region is displayed a second waveform. The second waveform represents a subset of data points of the first waveform. The second waveform also is shown in two dimensions. One dimension represents signal amplitude and one dimension represents signal frequency.
