RFmxGsmMXModAccResultsFetchPfer Method

Fetches the phase and frequency error measurement results for GSM.

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

Int32
Returns the status code of this method. The status code either indicates success or describes a warning condition.
