Scales the input waveform to DUT Average Input Power and then predistorts the waveform using the DPD polynomial or the lookup table.
Syntax
Namespace: NationalInstruments.RFmx.SpecAnMX
public int ApplyDpd(string selectorString, ComplexWaveform< ComplexSingle > waveformIn, RFmxSpecAnMXDpdApplyDpdIdleDurationPresent idleDurationPresent, double measurementTimeout, ref ComplexWaveform< ComplexSingle > waveformOut, out double appliedHeadroom)
Remarks
To scale the waveform correctly, specify whether the idle duration is present in the waveform.
This method maps to the RFmxSpecAn_DPDApplyDPD() function in C.
Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Pass an empty string. The signal name that is passed when creating the signal configuration is used. |
| waveformIn | ComplexWaveform< ComplexSingle > | Specifies the complex baseband equivalent of the RF signal on which to apply digital predistortion. |
| idleDurationPresent | RFmxSpecAnMXDpdApplyDpdIdleDurationPresent | Specifies whether the waveform contains an idle duration. |
| measurementTimeout | double | Specifies the timeout, in seconds, for fetching the specified measurement. |
| appliedHeadroom | out double | Specifies the headroom, in dB, applied to the predistorted waveform when you set the headroomMode parameter to Manual. |
| waveformOut | ref ComplexWaveform< ComplexSingle > | Upon return, contains the complex baseband equivalent of the RF signal on which to apply digital predistortion. |
Returns
Returns the status code of this method. The status code either indicates success or describes an error or warning condition.
