FPGA-Based Test Solutions

With capabilities for CW and pulsed signal generation to measure power, gain, and added efficiency, as well as 2-tone characterization for assessing video bandwidth, this platform is perfectly suited for in-depth power amplifier testing under base station-like conditions.

Additionally, the system supports LTE/5G modulated signal characterization, enabling precise evaluation of linearity under Digital Pre-Distortion (DPD) conditions.

Measure ACPR, EVM, power, and efficiency with complex modulated signals—all in one streamlined, high-performance test solution.
