Selecting Subcarrier Types to Display

Pilots Only (Magnitude and Phase Traces)

There are 12 pilot tones in each symbol (located at ± 5, 15, 25, 35, 45, 55 of the DC center point). When Pilots
only
is selected, each one of the traces (Magnitude and Phase) displays one data point at each pilot tone. This is
a particularly useful view for high data rate signals which use Dual Carrier Modulation.

Since the pilot tones are the reference for decoding, Magnitude and Phase are set values: magnitude is set at 1
and the phase of each tone varies between +/-45° and +/-135° (exact usage depends on data rate).
