public int FetchModulationResultsArray(string selectorString, double timeout, out double modulationCarrierPower, ref double[] lowerRelativePower, ref double[] upperRelativePower, ref double[] lowerAbsolutePower, ref double[] upperAbsolutePower)
Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Specifies a selector string comprising of the result name. If you do not specify the result name, the default result instance is used. The default is "" (empty string). |
| timeout | double | Specifies the timeout for fetching the specified measurement. This value is expressed in seconds. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the method waits until the measurement is complete. |
| modulationCarrierPower | out double | Upon return, contains the modulation carrier power. This value is expressed in dBm. |
| lowerRelativePower | ref double[] | Upon return, contains an array of relative powers measured at the negative modulation offset frequencies. This value is expressed in dB. The relative powers are measured relative to the integrated modulation power of the carrier. |
| upperRelativePower | ref double[] | Upon return, contains an array of relative powers measured at the positive modulation offset frequencies. This value is expressed in dB. The relative powers are measured relative to the integrated modulation power of the carrier. |
| lowerAbsolutePower | ref double[] | Upon return, contains an array of absolute powers measured at the negative modulation offset frequencies. This value is expressed in dBm. |
| upperAbsolutePower | ref double[] | Upon return, contains an array of absolute powers measured at the positive modulation offset frequencies. This value is expressed in dBm. |
Returns
Returns the status code of this method. The status code either indicates success or describes a warning condition.
