Parameters

selectorString

Type: SystemString
Specifies a selector string comprising of the result name, and offset number. If you do not specify the result name, the default result instance is used.

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.TdscdmaMXRFmxTdscdmaMXSemLowerOffsetMeasurementStatus
Upon return, contains the lower offset measurement status based on measurement limits and the failure criteria specified by the standard.

margin

Type: SystemDouble
Upon return, contains the margin from the limit mask value specified by the standard. This value is expressed in dB. Margin is defined as the minimum distance between the spectrum and the limit mask.

marginFrequency

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

marginAbsolutePower

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

marginRelativePower

Type: SystemDouble
Upon return, contains the power at which the margin occurs in the negative offset segment relative to the integrated power of the reference carrier. This value is expressed in dB.
