La description

Key facts The following modes are available with option R&S®SMAB-K25 for testing VOR and ILS receivers:
  • VOR
  • ILS Glide Slope Signal (ILS-GS)
  • ILS Localizer Signal (ILS-LOC)
  • Marker Beacon (MKR BCN)
  • Automatic Direction Finding (ADF)

Brief description When testing VOR/ILS receivers it is necessary to have a high degree of reliability. For that, the test source must generate the test signals precisely and accurately. Due to the low modulation errors and the very high level accuracy the R&S®SMA100B is the optimum source to generate highly precise VOR/ILS signals for testing avionics receivers.
