MCS Index
define the Modulation and Coding Scheme (MCS) index, of the PPDUs taking part in
the analysis, manually. This field is enabled for "MCS index to use" = "Meas only the
specified MCS" or "Demod all with specified MCS".
Remote command:
[SENSe:]DEMod:FORMat:MCSIndex on page 194
Nsts to use (IEEE 802.11 ac only)
Defines the the PPDUs taking part in the analysis depending on their Nsts.
Note: The terms in brackets in the following description indicate how the setting is
referred to in the "Signal Field" result display ("NSTS" column).
"Auto, same
type as first
PPDU:""(A1st)"
All PPDUs using the Nsts identical to the first recognized PPDU are
analyzed.
" Auto, individ-
ually for each
PPDU""(AI)"
All PPDUs are analyzed
"Meas only the
specified
Nsts""(M ...)"
Only PPDUs with the Nsts specified for the Nsts (IEEE 802.11ac
only) setting are analyzed
"Demod all
with specified
Nsts""(D ...)"
The Nsts (IEEE 802.11ac only) setting is used for all PPDUs.
Remote command:
[SENSe:]DEMod:FORMat:NSTSindex:MODE on page 195
Nsts (IEEE 802.11ac only)
Defines the Nsts of the PPDUs taking part in the analysis. This field is enabled for Nsts
to use (IEEE 802.11 ac only) = "Meas only the specified Nsts" or "Demod all with
specified Nsts".
Remote command:
[SENSe:]DEMod:FORMat:NSTSindex on page 195
STBC field
Defines the Space-Time Block Coding (STBC) field content of the PPDUs taking part in
the analysis.
"Auto, same
type as first
PPDU""(A1st)"
All PPDUs using a STBC field content identical to the first recognized
PPDU are analyzed.
"Auto, individu-
ally for each
PPDU""(AI)"
All PPDUs are analyzed.
