2.6.2.7.2 ILS-Glide Slope Modulation (ILS-GS)
Notes:
-
The following modulations cannot be set simultaneously and deactivate one another:
ILS-GS and AM, ILS-GS and PM if SOURCE PM = LFGEN2
ILS-GS and FM if SOURCE FM = LFGEN2
- In the AM, FM, PM and LF-output menu the message "ILS-GS" is displayed under
LFGEN2 if the ILS-GS modulation is activated.
- With setting CARRIER FREQ KNOB STEP= DEFINED, a change to modulation
ILS-LOC automatically causes the RF frequency to be adapted to the localizer value
which is coupled to the glide-slope setting.

MODE
Selection of the ILS-GS operating mode.
OFF ILS-GS modulation is switched off.
In menus AM, FM, PM and LF-OUTPUT, the original setting is
displayed under LFGEN2, the message "ILS-GS" is
eliminated.
NORM ILS-GS modulation is activated.
90 Hz Amplitude modulation of the output signal with the 90-Hz
signal content of the ILS-GS signal. The modulation depth of
the 90-Hz signal results from the settings of parameters SUM
OF DEPTH (SOD) and DDM according to:
AM(90 Hz) = 0,5 × (SOD + DDM × 100%)
