Noise Power Ratio measurements

Convenient and easy way to measure NPR over a maximum of 25 notches

A combination of the R&S®SMW200A vector signal generator and the R&S®FSW signal and spectrum analyzer equipped with the R&S®FSW-K19 option can be used to characterize two-port devices such as satellite transponders, power amplifiers and converters. The R&S®FSW-K19 measures Noise Power Ratio using either a notched comb signal (SMW-K61 required), a notched noise or a digitally modulated stimulus signal (SMW-K811) to determine how the DUT will perform.
