RFmxDemodMXDDemodResultsRead Method

Configures hardware for acquisition, performs measurement on acquired data for the modulation type configured using the ConfigureModulationType(String, RFmxDemodMXDDemodModulationType, RFmxDemodMXDDemodM, RFmxDemodMXDDemodDifferentialEnabled) method and returns the frequency offset, error vector magnitude (EVM), and modulation error ratio (MER) results.

Namespace: NationalInstruments.RFmx.DemodMX
Assembly: NationalInstruments.RFmx.DemodMX.Fx40 (in NationalInstruments.RFmx.DemodMX.Fx40.dll) Version: 24.5.0.49286 (24.5.0.49286)

Syntax

public int Read(
	string selectorString,
	double timeout,
	out double meanFrequencyOffset,
	out double meanRmsEvm,
	out double maximumPeakEvm,
	out double meanModulationErrorRatio
)
Public Function Read ( 
	selectorString As String,
	timeout As Double,
	<OutAttribute> ByRef meanFrequencyOffset As Double,
	<OutAttribute> ByRef meanRmsEvm As Double,
	<OutAttribute> ByRef maximumPeakEvm As Double,
	<OutAttribute> ByRef meanModulationErrorRatio As Double
) As Integer

Parameters

selectorString  String
Pass an empty string. The signal name that is passed when creating the signal configuration is used.
timeout  Double
Specifies the time, in seconds, for which the method waits for the measurement to complete. A value of -1 specifies that the method waits until the measurement is complete.
meanFrequencyOffset  Double

[Missing <param name="meanFrequencyOffset"/> documentation for "M:NationalInstruments.RFmx.DemodMX.RFmxDemodMXDDemodResults.Read(System.String,System.Double,System.Double@,System.Double@,System.Double@,System.Double@)"]

meanRmsEvm  Double
Upon return, contains the mean of the RMS EVM measured per acquisition.
maximumPeakEvm  Double
Upon return, contains the maximum of the peak EVM measured per acquisition.
meanModulationErrorRatio  Double
Upon return, contains the MER, in dB.

Return Value

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

Remarks

This method maps to the RFmxDemod_DDemodRead() function in C.
