After a capture, pressing the "Peak Find" button will set the marker to the peak
frequency.
Pressing the "Next Peak" button will find the next highest peak after the current marker.
Pressing "Peak Find" again will reset the marker to the peak frequency. Currently you
can only step through a limited number (20) of peaks with the "Next Peak" function.
Note that some external attenuation will be needed to avoid overloading the digitizer
input. All power meas urem ents from the analyzer will need to be adjusted for this to
get true power values.
