Fetches the frequency-modulated (FM) maximum deviation measurements.
Syntax
Namespace: NationalInstruments.RFmx.DemodMX
public int FetchFMMaximumDeviation(string selectorString, double timeout, out double maximumDeviation, out double maximumHalfPeakToPeak, out double maximumRms, out double maximumPositivePeak, out double maximumNegativePeak)
Remarks
This method maps to the RFmxDemod_ADemodFetchFMMaximumDeviation() 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. |
| maximumDeviation | out double | Upon return, contains the maximum frequency deviation, in hertz (Hz), of the FM signal measured across multiple acquisitions. |
| maximumHalfPeakToPeak | out double | Upon return, contains the maximum (peak-to-peak)/2 frequency variation, in Hz, around the nominal frequency of the FM carrier measured across multiple acquisitions. |
| maximumRms | out double | Upon return, contains the maximum RMS frequency deviation, in Hz, of the FM signal measured across multiple acquisitions. |
| maximumPositivePeak | out double | Upon return, contains the maximum positive peak frequency deviation, in Hz, of the FM signal measured across multiple acquisitions. |
| maximumNegativePeak | out double | Upon return, contains the maximum negative peak frequency deviation, in Hz, of the FM signal measured across multiple acquisitions. |
Returns
Returns the status code of this method. The status code either indicates success or describes a warning condition.
