R&S®FS-K15 VOR/ILS Measurement Demodulator

for R&S®FSMR/R&S®FSU/R&S®FSQ - Analysis for VOR and ILS signals

  • Overview

Key Facts

  • Frequency range
  • Level range
  • Measurement functions VOR
  • VOR phase

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.

Key Facts

Frequency range: 107 MHz to 120 MHz and 319 MHz to 341 MHz specified; can be used in the frequency range of the base unit
Level range: -60 dBm to +30 dBm
Measurement functions VOR: VOR phase, modulation depth and frequency for 30 Hz, subcarrier, identifier, 9.96 kHz subcarrier deviation, modulation depth and frequency of the subcarrier, THD; phase between 90 Hz and 150 Hz signal
VOR phase: 0° to 360°, 0.1° resolution
Measurement uncertainty VOR phase: 0.003°
Measurement functions ILS: DDM, SDM, modulation depth and frequency at 90 Hz/150 Hz/identifier, THD
Measurement range DDM: 0 DDM to 0.4 DDM
Measurement uncertainty DDM: 0.0002 DDM + 1 % of reading

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.
