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.

Inputs/Outputs
![]() Memory Polynomial Lag Memory Depth specifies the lag memory depth cross term of the DPD polynomial when you set the DPD Model property to Generalized Memory Polynomial. This value corresponds to Qb in the equation for the generalized memory polynomial. The default value is 0. ![]() Memory Polynomial Lead Memory Depth specifies the lead memory depth cross term of the DPD polynomial when you set the DPD Model property to Generalized Memory Polynomial. This value corresponds to Qc in the equation for the generalized memory polynomial. The value of this parameter must be greater than or equal to the value of the Memory Polynomial Max Lead parameter. The default value is 0. ![]() Selector String specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used. The default value is "" (empty string). Example: "" "signal::sig1" You can use the RFmxSpecAn Build Signal String VI to build the selector string. ![]() Instrument Handle In specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI. ![]() Memory Polynomial Lead Order specifies the lead order cross term of the DPD polynomial when you set the DPD Model property to Generalized Memory Polynomial. This value corresponds to Kc in the equation for the generalized memory polynomial. The default value is 0. ![]() Memory Polynomial Lag Order specifies the lag order cross term of the DPD polynomial when you set the DPD Model property to Generalized Memory Polynomial. This value corresponds to Kb in the equation for the generalized memory polynomial. The default value is 0. ![]() error in describes error conditions that occur before this node runs. This input provides standard error in functionality. ![]() Memory Polynomial Max Lead specifies the maximum lead stagger cross term of the DPD polynomial when you set the DPD Model property to Generalized Memory Polynomial. This value corresponds to Mc in the equation for the generalized memory polynomial. The default value is 0. ![]() Memory Polynomial Max Lag specifies the maximum lag stagger cross term of the DPD polynomial when you set the DPD Model property to Generalized Memory Polynomial. This value corresponds to Mb in the equation for the generalized memory polynomial. The default value is 0. ![]() Instrument Handle Out passes a reference of your RFmx session to the next VI. ![]() error out contains error information. This output provides standard error out functionality. |
