Brief Description The R&S®FS-K15 option measures the most important parameters of VOR and ILS signals such as VOR phase, ILS DDM as well as the modulation depth and frequency of the individual signal components. Since the option is integrated into the R&S®FSMR measuring receiver, the complete calibration and verification of VOR/ILS generators or generator parts of air navigation testers is easy – no additional equipment required. Together with the spectrum and signal analyzers of the R&S®FSU and R&S®FSQ family, the R&S®FS-K15 option is particularly suitable for the development and operational monitoring of VOR and ILS installations. The low measurement uncertainty meets the requirements of ILS CAT III applications. The selective distortion measurement completes the measurement functions and allows THD measurements without having to switch off individual signal components.''
