Using ILS Localizer Softkeys
Figure 14-13 ILS Localizer Softkeys
When testing an ILS [Instrument Landing System],
the following ILS Localizer parameters can be set:
- Sets Right Frequency
-Sets DDM Polarity
Left | Right | In-line
- Sets DDM (Difference
in Depth of Modulation)
- Sets DDM in uA
- Sets DDM in %.
DDM of 1% is
equivalent to 0.001
- Sets the Sum of
Depth of Modulation
- Sets the Phase of the
Right signal relative to
the Left signal
- Turns off the Left (90 Hz)
and Right (150 Hz)
ILS Localizer signals
- Turns on the Left (90 Hz)
and Right (150 Hz)
ILS Localizer signals
- Turns off the Left (90 Hz)
ILS Localizer signal
- Turns off the Right (150 Hz)

- Sets Left Frequency
- Sets a Carrier Frequency by selecting an Index from 1 to 40.
(Default: Index is 1 and corresponds to 108.10 MHz)
