RFmx
Fetches the frequency-modulated (FM) mean deviation measurements.
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 FetchFMMeanDeviation( string selectorString, double timeout, out double meanDeviation, out double meanHalfPeakToPeak, out double meanRms, out double meanPositivePeak, out double meanNegativePeak )
Public Function FetchFMMeanDeviation ( selectorString As String, timeout As Double, <OutAttribute> ByRef meanDeviation As Double, <OutAttribute> ByRef meanHalfPeakToPeak As Double, <OutAttribute> ByRef meanRms As Double, <OutAttribute> ByRef meanPositivePeak As Double, <OutAttribute> ByRef meanNegativePeak As Double ) As Integer
Parameters
- selectorString String
- Specifies the result name. Example: "", "result::r1". You can use the BuildResultString(String) method to build the selectorString.
- 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.
- meanDeviation Double
- Upon return, contains the mean positive peak frequency deviation,in Hz, of the FM signal.
- meanHalfPeakToPeak Double
- Upon return, contains the mean (peak-to-peak)/2 frequency variation, in Hz, around the nominal frequency of the FM carrier.
- meanRms Double
- Upon return, contains the mean RMS frequency deviation of the FM signal.
- meanPositivePeak Double
- Upon return, contains the mean positive peak frequency deviation, in Hz, of the FM signal.
- meanNegativePeak Double
- Upon return, contains the mean negative peak frequency deviation of the FM signal.
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_ADemodFetchFMMeanDeviation() function in C.
