PXI Speed, Size, and Synchronization Capabilities Improve Measurement Time for Modern Load Pull Test Systems
Load pull solution vendors are combining their expertise with NI PXI hardware and LabVIEW system design software to overcome the increasingly difficult source and load pull characterization requirements placed on microwave power amplifiers for aerospace and defense and wireless infrastructure applications.
Load pull characterization is an essential tool to increase the efficiency of power amplifiers. Due to time and cost, vendors have historically performed load pull during design. Today, however, the industry-leading speed and flexibility of a PXI-based system make it possible to verify power amplifier performance during production test.
