freq_detect_peaks
Purpose
: This command returns frequencies in signal amplitude order (see next figure). You get to
choose the total number of peaks. If a given peak detected is not greater than the
minimum level (
min_level
), that peak will be dropped and the frequency will be
returned as zero. If the peak detected is a part of a single frequency spectrum, this peak
will be ignored. Each measured peak frequency will have a corresponding measured
signal level returned in the
measured_signal_levels
array.
