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. The constellations are color coded.
Press this submenu key to display reference points for the various constellations. On is the default state.
Press this submenu key to return to the Demodulator menu.
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 fail. This mask is referenced from the average of all 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 subcarriers. Because some subcarriers are not used in OFDMA, their values are set to 0 (zero).
EVM vs Symbol
Press this submenu key to display the EVM (rms) values versus OFDM symbols.
Press this submenu key to display a summary table of all of the modulation‑related numerical measurement results. The following measurements are displayed:
DL‑MAP Parameter Tree
Press this submenu key to display the DL‑MAP information in Auto mode (from the decoded results) or in Manual mode (from the parsed information, which is from the .xml parameter file).
