4.3 Demod Settings Dialog Box
In the "Demod Settings" dialog box, the settings associated with the signal modulation
can be modified. The settings under "PPDU to Analyze" specify the characteristics of
the PPDUs to be considered in the measurement results. Only the PPDUs which meet
the criteria specified in this group will be included in measurement analysis if the "Use
Header Content" option is activated. The tracking settings allow various errors in mea-
surement results to be compensated for.
