RFmx
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
Int32Returns 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.
