Press the Constellation submenu key to set the demodulation to Constellation view. The constellation view shows the constellation of the demodulated data symbols over one frame. When demodulation is set to Constellation view, press this submenu key again to open the Constellation menu.
Press this submenu key to display reference points for the various constellations. On is the default state.
Press this submenu key to show the spectral flatness data that is measured from the preamble at the channel estimation step. The deviation of the spectral flatness from the average of all the carriers is shown in dB.
A mask that conforms to the specification is overlaid on the trace. Green color on the mask indicates pass, and red color on the mask indicates regions of the mask where the signal fails.
0 to ± 50 subcarriers < ± 2 dB
± 50 to ± 100 subcarriers < + 2 dB, and – 4 dB
This mask is referenced from the average of all 200 subcarrier amplitude values. Absolute delta of the power between adjacent subcarriers is displayed as a numerical value in dB.

EVM vs Sub Carrier
Press this submenu key to display the EVM (rms) values versus OFDM subcarriers. The pilot subcarriers are shown in orange.
EVM vs Symbol
Press this submenu key to display the EVM (rms) values versus OFDM symbols.
