Power Amplifier Envelope Tracking and Digital Predistortion Test Solution
应用文章
This document presents a PXI-based test solution for characterizing power amplifiers using Envelope Tracking (ET) and Digital Predistortion (DPD). The solution combines RF signal generation and analysis within the M9410A/15A PXIe Vector Transceiver, while the M5301A PXIe AWG generates differential envelope waveforms synchronized through the PXI backplane. Key functions including RF waveform configuration, envelope generation, ETPS control, timing alignment, and DPD processing are integrated into the N9055EM0E X-apps Power Amplifier Measurement Application, providing a streamlined and centralized test workflow.
