● The second line shows the R&S FSV-K91 parameters affecting which PPDUs take
part in the analysis and which do not (this functionality is referred as "logical filter").
●
The value inside the white rectangle indicates the current "logical filter" setting.

Measurement settings
The settings for this measurement are defined in the "Demod Settings" for the IEEE
802.n standard, and in the "Advanced Demod Settings" for the IEEE 802.n (MIMO)
standard.
Note that for the IEEE 802.n standard, the "Use Signal Field Content" setting must be
activated for Signal Field measurements.
The following table indicates which PPDU properties are displayed in the result table of
the Signal Field measurement and which R&S FSV-K91 settings are used to obtain
these properties.
