For optimizing active RF components, the FS K130 distortion analysis software allegedly allows users to characterize and linearize amplifiers quickly and compensates for memory effects exhibited by many current amplifiers. A typical test setup consists of a spectrum analyzer, signal generator, and a PC. It measures the amplifier's characteristics and calculates the necessary corrections to attain a linear output signal. The application, which runs on Windows XP, is designed for a test setup based on the FSV or FSQ spectrum analyzers as well as the SMBV or SMU200A signal generators. The software has two functions: to control the instruments and characterize the amplifier using the same signal waveform that will be driving it. ROHDE & SCHWARZ INC., Columbia, MD. (888) 837-8772.
