R&S®FS-K15 VOR/ILS Measurement Demodulator
for R&S®FSMR /R&S®FSU /R&S®FSQ - Analysis for VOR and ILS signals
Applications
Measurement of a VOR signal and the VOR phase
Operation is easy: after selection of the operating mode, in this case VOR, the
Both RF signals and signals in the baseband can be analyzed via the audio input.
Measurement of an ILS localizer
The precise ILS analysis measures DDM (difference in depth of modulation) at a low uncertainty of only 0.00002 DDM + 1 % even for signals with very low levels.
THD and distortion measurement of an ILS signal
The AF spectrum display is used to analyze distortion products in detail. The levels of sum products (such as 240 Hz as the sum of 90 Hz and 150 Hz) or individual harmonics can selectively be measured. With the
