FSV-K91/91n/91ac/91p
196Operating Manual 1176.7649.02 ─ 04
Parameters:
<Mode> FBURst | ALL | MEASure | DEMod
FBURst
The Nsts of the first PPDU is detected and subsequent PPDUs
are analyzed only if they have the same Nsts (corresponds to
"Auto, same type as first PPDU")
ALL
All recognized PPDUs are analyzed according to their individual
Nsts (corresponds to "Auto, individually for each PPDU")
MEASure
Only PPDUs with the Nsts specified by [SENSe:]DEMod:
FORMat:NSTSindex are analyzed
DEMod
The "Nsts" index specified by [SENSe:]DEMod:FORMat:
NSTSindex is used for all PPDUs.
*RST:
FBURst
Example:
SENS:DEM:FORM:NSTS:MODE MEAS
SENS:DEM:FORM:NSTS 1
Manual operation: See "Nsts to use (IEEE 802.11 ac only)" on page 106
[SENSe:]DEMod:FORMat:SIGSymbol <State>
If this command is set to ON, the signal symbol field of the burst is analyzed to deter-
mine the details of the burst. Only burst which match the supplied burst type and mod-
ulation are considered in results analysis. For IEEE 802.11b this command can only be
queried as the decoding of the signal field is always performed for the IEEE 802.11b
standard.
Parameters:
<State> ON | OFF
Example:
DEM:FORM:SIGS ON
Specifies that the signal symbol field should be decoded.
Mode: WLAN
Manual operation: See "Signal Field Content (IEEE 802.11a, g (OFDM), j & n
(SISO), p)" on page 98
See "Use Header Content (IEEE 802.11b, g – Single Carrier)"
on page 98
[SENSe:]DEMod:TXARea <State>
If enabled, the R&S FSV WLAN application initially performs a coarse burst search on
the input signal in which increases in the power vs time trace are detected. Further
time-consuming processing is then only performed where bursts are assumed. This
improves the measurement speed for signals with low duty cycle rates.
