NI’s PXI and LabVIEW meet next-gen load pull measurement speed challenges

USA: At the International Microwave Symposium, National Instruments (NATI) has announced joint development on load pull solutions from Anteverta Microwave, Focus Microwaves, Maury Microwave and Mesuro.

These 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.

NI PXI is part of the LabVIEW reconfigurable I/O (RIO) architecture, which includes the latest computing technologies, such as multicore CPUs and FPGAs, and a single, common development language. Anteverta Microwave, Focus Microwaves, Maury Microwave and Mesuro are using this architecture, along with their unique approaches, to help their customers simplify test and decrease time to market.
