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 FetchPfer( string selectorString, double timeout, out double meanRmsPhaseError, out double maximumRmsPhaseError, out double meanPeakPhaseError, out double maximumPeakPhaseError, out double meanFrequencyError, out int peakSymbol )
Public Function FetchPfer ( selectorString As String, timeout As Double, <OutAttribute> ByRef meanRmsPhaseError As Double, <OutAttribute> ByRef maximumRmsPhaseError As Double, <OutAttribute> ByRef meanPeakPhaseError As Double, <OutAttribute> ByRef maximumPeakPhaseError As Double, <OutAttribute> ByRef meanFrequencyError As Double, <OutAttribute> ByRef peakSymbol As Integer ) 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.
- meanRmsPhaseError Double
-
Upon return, contains the mean of RMS phase error values measured over all acquisition time slots. This value is expressed in degrees.
- maximumRmsPhaseError Double
-
Upon return, contains the maximum of RMS phase error values measured over all acquisition time slots. This value is expressed in degrees.
- meanPeakPhaseError Double
-
Upon return, contains the mean of peak phase error values measured over all acquisition time slots. This value is expressed in degrees.
- maximumPeakPhaseError Double
-
Upon return, contains the maximum of peak phase error values measured over all acquisition time slots. This value is expressed in degrees.
- meanFrequencyError Double
-
Upon return, contains the mean of frequency error values measured over all acquisition time slots. This value is expressed in Hz.
- peakSymbol Int32
-
Upon return, contains the symbol number in the useful portion of the burst corresponding to phase error value in the maximumPeakPhaseError parameter.
Return Value
Int32Returns the status code of this method. The status code either indicates success or describes a warning condition.
