Distortion Analysis Software Helps Optimize Active RF Components
Rohde & Schwarz has introduced the R&S FS K130 distortion analysis software for optimizing active RF components such as power amplifiers and mixers. This software allows users to characterize and linearize amplifiers and even compensating for memory effects. The test setup consists of a spectrum analyzer, a signal generator, and a PC. The setup measures the amplifier's characteristics and calculates the correction required to attain a linear output signal. The R&S FS-K130, which runs on Windows XP, was designed for a test setup based on the R&S FSV or R&S FSQ spectrum analyzers as well as the R&S SMBV or R&S SMU200A signal generators from Rohde & Schwarz. The software has two functions. It controls the instruments and it characterizes the amplifier using the same signal waveform that will be driving the amplifier. The R&S FS-K130 distortion analysis software offers various mathematical simulation models, such as the Volterra series and a simpler polynomial expression to model amplifier behavior.
