6 List Sequence Measurements
List Sequence Measurements
[:SENSe]:EVM:TIME:RESult:MAX <integer>
Max Result
Length
Max Result Length specifies a
maximum result length.
If the auto-detected length is
greater than the specified
maximum result length, the
maximum result length is used
instead
[:SENSe]:EVM:TIME:RESult:SIG OFF|ON|0|1
From SIG
Symbols
For 802.11n, if From SIG Syms
is On:
The result length is detected
from the High Throughput Signal
Field. It compares the decoded
length information to the Max
Result Length parameter and
uses the smaller value as the
measurement result length.
For 802.11n, if From SIG Syms
Off:
When Result Length is Auto, the
analyzer automatically
determines the measurement
result length by burst search. It
compares the detected result
length to Max Result Length
parameter and uses the smaller
value as the measurement result
length.
:CALCulate:EVM:SUBCarrier
ALL|PILOt|SINGle
Subcarrier
This parameter specifies
whether the demodulation
results are for all subcarriers in
the signal, or for a single
subcarrier , or for just the pilot
subcarriers.
:CALCulate:EVM:SUBCarrier:COUNt
<integer>
Subcarrier
Number
This parameter specifies the
demodulation results are for
which subcarrier. When
Subcarrier selects “Single”, this
number will indicate which
subcarrier is used to do
demodulation
[:SENSe]:EVM:FILTer:REFerence:TYPE
GAUSsian|RECT|RC
Reference
Filter
This parameter controls the
reference filter type used when
computing the reference data for
computing EVM
[:SENSe]:EVM:FILTer:ALPHa <real>
Alpha/BT
This parameter is used only
when the Reference Filter is set
to “GAUSSIAN” or “Raised
Cosine”, or the Measurement
