Use the VIs on this palette to configure DPD measurements. You can also use the RFmxSpecAn Property Node to configure additional properties.

RFmxSpecAn DPD Configure Measurement Interval VI
Configures the acquisition time, in seconds, for the DPD measurement.
RFmxSpecAn DPD Configure Measurement Sample Rate VI
Configures the acquisition sample rate, in Samples per second (S/s), for the DPD measurement.
RFmxSpecAn DPD Configure Synchronization Method VI
Configures the synchronization method used to synchronize the reference waveform and acquired waveform.
RFmxSpecAn DPD Configure DUT Average Input Power VI
Configures the average power, in dBm, of the signal at the input port of the device under test (DUT).
RFmxSpecAn DPD Configure Reference Waveform VI
Configures the complex baseband equivalent of the RF signal applied at the input port of the DUT when performing the DPD measurement.
RFmxSpecAn DPD Configure DPD Model VI
Specifies the DPD model used by the DPD measurement.
RFmxSpecAn DPD Configure Lookup Table Step Size VI
Configures the step size, in dB, of input power levels in the predistortion lookup table when you set the DPD Model property to Lookup Table.
RFmxSpecAn DPD Configure Lookup Table AM to AM Curve Fit VI
Configures the degree of the polynomial and the approximation method used for polynomial approximation of the AM-to-AM response of the device under test (DUT) when you set the DPD Model property to Lookup Table.
RFmxSpecAn DPD Configure Lookup Table AM to PM Curve Fit VI
Configures the degree of the polynomial and the approximation method, used for polynomial approximation of the AM-to-PM response of the device under test (DUT) when you set the DPD Model property to Lookup Table.
RFmxSpecAn DPD Configure Lookup Table Threshold VI
Configures the threshold level for the samples that are considered for the DPD measurement when you set the DPD Model property to Lookup Table. Set the Threshold Enabled parameter to True to reject low-power signals affected by noise and distortion.
RFmxSpecAn DPD Configure Lookup Table Type VI
Configuers the type of DPD Lookup Table.
RFmxSpecAn DPD Configure Memory Polynomial VI
Configures the order and memory depth of the DPD polynomial when you set the DPD Model property to Memory Polynomial or Generalized Memory Polynomial.
RFmxSpecAn DPD Configure Generalized Memory Polynomial Cross Terms VI
Configures the cross terms of the generalized memory polynomial when you set the DPD Model property to Generalized Memory Polynomial. Use the RFmxSpecAn DPD Configure Memory Polynomial VI to configure the normal terms in the DPD polynomial, along with configuring the cross terms when you set the DPD Model property to Generalized Memory Polynomial.
RFmxSpecAn DPD Configure Iterative DPD Enabled VI
Configures the iterative computation of the DPD polynomial in accordance with the indirect-learning architecture when you set the DPD Model property to Memory Polynomial or Generalized Memory Polynomial.
RFmxSpecAn DPD Configure Previous DPD Polynomial VI
Configures the previous DPD polynomial when you set the DPD Model property to Memory Polynomial or Generalized Memory Polynomial. Set the Iterative DPD Enabled property to True, to apply the previous DPD polynomial on the reference waveform, which is used to compute the value of the DPD polynomial for the current iteration.
RFmxSpecAn DPD Configure Averaging VI
Configures averaging for the DPD measurement.
RFmxSpecAn DPD Apply Pre-DPD Signal Conditioning VI
Applies signal conditioning on the input waveform in the form of crest factor reduction before using the output waveform as the reference waveform for DPD measurement.
RFmxSpecAn DPD Configure Extract Model Target Waveform VI
Configures the complex baseband equivalent of the Target waveform desired at the output of the Predistorter Model to be extracted when performing the DPD measurement.
