Rohde & Schwarz Direct DPD measurement application Requires R&S®FSW-K18 (software license)
The R&S®FSW-K18D Direct DPD measurement application is a software option for the R&S®FSW signal and spectrum analyzer. It enables direct digital predistortion (DPD) measurements, allowing users to analyze and optimize the linearization of power amplifiers. This application provides comprehensive tools for evaluating the performance of DPD algorithms by measuring key parameters such as adjacent channel leakage ratio (ACLR), error vector magnitude (EVM), and spectrum emission mask compliance. The R&S®FSW-K18D requires the base R&S®FSW-K18 amplifier measurement application to operate. It is designed for use in wireless communications development and production environments, supporting a wide range of standards and signal types.
