Access:
► Select "VOR > General"
This dialog comprises general settings of the VOR standard, the default and the
"Save/Recall" settings.
By default, a VOR modulation signal is set on an RF carrier with a frequency of 108
MHz or ICAO channel 17X. The 9.96 kHz subcarrier signal is frequency modulated
with a 30.00 Hz reference signal. The COM/ID signal has 1.02 kHz frequency, the
variable phase signal 30.00 Hz frequency.
If enabled, the avionic standard modulation is displayed in the "Modulation" tile as
follows:
● "Avionic: VOR" for enabled VOR modulation
● "Avionic ILS: Glide Slope/Localizer/Marker Bcn" for enabled ILS glide slope/
localizer/marker beacons modulation
● "Avionic: ADF" for enabled ADF modulation
Changing a parameter in the avionic standards causes an instant signal change in the
R&S SMA100B. There is no extra measurement cycle to calculate the RMS value of
the baseband signal to set the correct RF level.
If the avionics standard is activated for the first time, or after every subsequent on/off
sequence, the measurement cycle will take place to determine the correct RF level.
Every subsequent parameter change in the avionic standard is performed without
another measurement cycle to provide a continuous signal output.
