Standard State Description
IEEE 802.11g (OFDM) On Only PPDUs with exactly the number of data symbols or duration
specified in the "Payload Length" field are considered for measure-
ment analysis. (See "Payload Length (IEEE 802.11b, g)" on page 102)
Off Only PPDUs within the range of data symbols or duration specified by
the "Min Payload Length" and "Max Payload Length" fields are consid-
ered for measurement analysis. (See "Min Payload Length (IEEE
802.11b, g)" on page 102 and "Max Payload Length (IEEE 802.11b,
g)" on page 102)

Data Symbols (IEEE 802.11a, ac, j, n, p)
Specifies the number of data symbols of a PPDU to be considered in measurement
analysis. This field is only available if the "Equal PPDU Length" option is activated.
Remote command:

Min Data Symbols (IEEE 802.11a, ac, j, n, p)
Specifies the minimum number of data symbols of a PPDU to be considered in mea-
surement analysis. This field is only available if the "Equal PPDU Length" option is
deactivated.

Max Data Symbols (IEEE 802.11a, ac, j, n, p)
Specifies the maximum number of data symbols of a PPDU to be considered in mea-
surement analysis. This field is only available if the "Equal PPDU Length" option is
deactivated.

Channel Estimation Range (IEEE 802.11a, ac, g (OFDM), j, n, p)
Specifies how accurately the EVM results are calculated.
"Preamble" The channel estimation is performed in the preamble as required in the standard.
"Payload" The channel estimation is performed in the payload.
