Example:
FETC:BURS:BERP:DATA:MAX?
Usage: Query only
Mode: WLAN
FETCh:BURSt:COUNt[:ALL]?
This command returns the number of analyzed bursts.
Example:
FETC:BURS:COUN?
The analyzed number of bursts is returned.
Usage: Query only
Mode: WLAN
FETCh:
BURSt:CRESt[:AVERage]?
FETCh:BURSt:CRESt:MAXimum?
FETCh:BURSt:CRESt:MINimum?
This command returns the average, minimum or maximum determined CREST factor
(= ratio of peak power to average power) in dB.
Example:
FETC:BURS:CRES:MAX?
The maximum calculated crest factor from the most recent mea-
surement is returned.
Usage: Query only
Mode: WLAN
FETCh:BURSt:EVM:[IEEE]:AVERage?
FETCh:BURSt:EVM:[IEEE]:MAXimum?
FETCh:BURSt:EVM:[IEEE]:MINimum?
This command returns the error vector magnitude measurement results summary
(average, minimum or maximum value) in dB for the IEEE 802.11b standard. This
result is the value before filtering.
Example:
FETC:BURS:EVM:MAX?
The maximum EVM recorded before filtering.
Usage: Query only
Mode: WLAN
FETCh:BURSt:EVM:ALL:AVERage?
FETCh:BURSt:EVM:ALL:MAXimum?
FETCh:BURSt:EVM:ALL:MINimum?
This command returns the error vector magnitude measurement results summary
(average, minimum or maximum value) in dB. This is a combined figure that represents
the pilot, data and the free carrier.
