La description

Key Facts The R&S®EVS-K4 option enables the R&S®EVS300 to perform an FFT (fast Fourier transformation) of the demodulated RF signal or the signal supplied to the baseband input. Using this method, harmonics and intermodulation products from ILS, VOR and marker beacon signals can be analyzed. In addition to displaying the spectrum in logarithmic or linear form, various window functions such as Hann and flat top can be selected. Marker and delta marker functions make it easy to read the levels and frequencies.
