) As Integer

Parameters

selectorString

Type: SystemString
Specifies a selector string comprising of the result name, subblock number, carrier number, and offset number. If you do not specify the result name, the default result instance is used. Example:
"subblock0/offset0"
"result::r1/subblock0/offset0"
You can use the BuildOffsetString(String, Int32) method to build the selector string.

timeout

Type: SystemDouble
Specifies the timeout for fetching the specified measurement. This value is expressed in seconds. 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.

measurementStatus

Type: NationalInstruments.RFmx.NRMXRFmxNRMXSemLowerOffsetMeasurementStatus
Upon return, contains the measurement status indicating whether the power before and after the burst is within the standard defined limit.

margin

Type: SystemDouble
Upon return, contains the margin from the absolute limit mask for lower (negative) offset. Margin is defined as the minimum difference between the spectrum and the limit mask. This value is expressed in dB.

marginFrequency

Type: SystemDouble
Upon return, contains the frequency at which the margin occurs in the lower offset. This value is expressed in Hz.

marginAbsolutePower

Type: SystemDouble
Upon return, contains the power at which the margin occurs in the lower offset segment. This value is expressed in dBm.

marginRelativePower

Type: SystemDouble
Upon return, contains the power at which the margin occurs in the lower offset segment. This value is expressed in dB.
