Fetches the frequency-modulated (FM) mean deviation measurements.
Syntax
Namespace: NationalInstruments.RFmx.DemodMX
public int FetchFMMeanDeviation(string selectorString, double timeout, out double meanDeviation, out double meanHalfPeakToPeak, out double meanRms, out double meanPositivePeak, out double meanNegativePeak)
Remarks
This method maps to the RFmxDemod_ADemodFetchFMMeanDeviation() function in C.
Parameters
| Name | Type | Description |
|---|---|---|
| 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 | out double | Upon return, contains the mean positive peak frequency deviation,in Hz, of the FM signal. |
| meanHalfPeakToPeak | out double | Upon return, contains the mean (peak-to-peak)/2 frequency variation, in Hz, around the nominal frequency of the FM carrier. |
| meanRms | out double | Upon return, contains the mean RMS frequency deviation of the FM signal. |
| meanPositivePeak | out double | Upon return, contains the mean positive peak frequency deviation, in Hz, of the FM signal. |
| meanNegativePeak | out double | Upon return, contains the mean negative peak frequency deviation of the FM signal. |
Returns
Returns the status code of this method. The status code either indicates success or describes a warning condition.
