MKPX

The default peak-excursion value is 3 dB for signals displayed on a logarithmic scale. This means that any signal with an excursion of less than 3 dB on either side of its bandwidth shape is not identi￿ed as a signal. If the marker-peak command, MKPK HI , is executed on such a signal, the analyzer does not place a marker at the signal peak. For signals displayed on a linear scale, the default peak excursion equals

excursion = 1 0 10

Note that if the peak excursion is too small, noise spikes are identi￿ed as signals. Use VAVG or SMOOTH to minimize noise spikes so that signal peaks can be distinguished from noise spikes.
