Fetches the modulation power trace and frequency offset.
Namespace: NationalInstruments.RFmx.GsmMX
Assembly: NationalInstruments.RFmx.GsmMX.Fx40 (in NationalInstruments.RFmx.GsmMX.Fx40.dll) Version: 24.5.0.49286 (24.5.0.49286)
Syntax
public int FetchModulationPowerTrace( string selectorString, double timeout, ref float[] offsetFrequency, ref float[] absolutePower, ref float[] relativePower )
Public Function FetchModulationPowerTrace ( selectorString As String, timeout As Double, ByRef offsetFrequency As Single(), ByRef absolutePower As Single(), ByRef relativePower As Single() ) As Integer
Parameters
- selectorString String
-
Specifies a selector string comprising of the result name. If you do not specify the result name, the default result instance is used. The default is "" (empty string).
Example:
""
"result::r1"
You can use the BuildResultString(String) method to build the selector string. - timeout Double
- 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.
- offsetFrequency Single
-
Upon return, contains an array of modulation offset frequencies at which the measurement is performed in an ascending order. This value is expressed in Hz.
- absolutePower Single
-
Upon return, contains an array of absolute powers corresponding to the modulation offset frequency list. This value is expressed in dBm.
- relativePower Single
-
Upon return, contains an array of relative powers corresponding to modulation offset frequency list. This value is expressed in dB.
Return Value
Int32Returns the status code of this method. The status code either indicates success or describes a warning condition.
