Parameters

selectorString

Type: SystemString
Specifies a selector string comprising of the result name, segment number, and chain number. If you do not specify the result name, the default result instance is used. Example:
"segment0/chain0"
"result::r1/segment0/chain0"
You can use the BuildChainString(String, Int32) method to build the selector string.

timeout

Type: SystemDouble
Specifies the timeout for fetching the specified measurement. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the method waits until the measurement is complete. This value is expressed in seconds.

measurementStatus

Type: NationalInstruments.RFmx.WlanMXRFmxWlanMXSemUpperOffsetMeasurementStatus
Upon return, contains an array of upper offset (positive) segment measurement status, indicating whether the spectrum exceeds the SEM measurement mask limits in the upper offset segments.

margin

Type: SystemDouble
Upon return, contains an array of margins from the SEM measurement mask for the upper offset. This value is expressed in dB. Margin is defined as the maximum difference between the spectrum and the mask.

marginFrequency

Type: SystemDouble
Upon return, contains an array of frequencies corresponding to the margins for the upper offsets. This value is expressed in Hz.

marginAbsolutePower

Type: SystemDouble
Upon return, contains an array of absolute powers corresponding to the margins for the upper (positive) offsets. This value is expressed in dBm.

marginRelativePower

Type: SystemDouble
Upon return, contains an array of relative powers corresponding to the margins for the upper (positive) offsets. The relative powers are relative to the peak power of the carrier channel. This value is expressed in dB.
