Syntax
Namespace: NationalInstruments.RFmx.SpecAnMX
public int FetchPredistortedWaveform(string selectorString, double timeout, ref ComplexWaveform< ComplexSingle > predistortedWaveform, out double papr, out double powerOffset, out double gain)
Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Pass an empty string. The signal name that is passed when creating the signal configuration is used. |
| timeout | double | Specifies the timeout, in seconds, for fetching the specified measurement. 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. |
| predistortedWaveform | ref ComplexWaveform< ComplexSingle > | Upon return, contains the predistorted waveform output after the measurement. |
| papr | out double | Upon return, contains the peak-to-average power ratio of the waveform obtained after applying digital predistortion. This value is expressed in dB. |
| powerOffset | out double | Upon return, contains the change in the average power in the waveform due to applying digital predistortion. This value is expressed in dB. |
| gain | out double | Upon return, contains the gain of the device under test. This value is expressed in dB. |
Returns
Returns the status code of this method. The status code either indicates success or describes a warning condition.
