Demod Settings (IEEE 802.ac, n (MIMO) only)
Determines whether the settings are defined automatically or manually.
"Auto All"
Automatically sets all Advanced demodulation settings to "Auto, same
as first PPDU".
"Manual"
Restores all settings to the state prior to activating "Auto All".

Signal Field Content (IEEE 802.11a, g (OFDM), j & n (SISO), p)
Activates or deactivates the decoding of the captured PPDU data.
"ON"
Only the PPDUs are included in the results analysis whose modula-
tion format specified in the signal symbol field matches the modula-
tion format specified in the "Analyze PSDU Mod (IEEE 802.11n,
SISO)" on page 99 field.
"OFF"
The data is demodulated according to the modulation scheme speci-
fied in the "Demodulator (IEEE 802.11a, b, g, j, p)" on page 100 field.
If any of the analyzed data has a modulation different to that specified
the results will be of limited use.
Remote command:

Use Header Content (IEEE 802.11b, g – Single Carrier)
Activates or deactivates the PLCP header field decoding of the captured PPDU data.
"ON"
Only the PPDUs are included in the results analysis whose modula-
tion format specified in the signal symbol field matches the modula-
tion format specified in the "Analyze PSDU Mod (IEEE 802.11n,
SISO)" on page 99 field.
"OFF"
The data is demodulated according to the modulation scheme speci-
fied in the "Demodulator (IEEE 802.11a, b, g, j, p)" on page 100 field.

PPDU Type (IEEE 802.11a, g (OFDM, Single Carrier), j, n, p)
Specifies the type of PPDU to be included in measurement analysis. Only one PPDU
type can be selected for the measurement results. The following PPDU types are sup-
ported:
