Parameters:
<Current> float
Range: -9.6775E-4 to 9.6775E-4
Increment: 1E-7
*RST: 0
Example: See Example "Configure and generate an ILS localizer signal"
on page 595.
Manual operation: See "DDM Current" on page 157
[:SOURce<hw>]:ILS:LOCalizer:DDM:DIRection
<Direction>
Sets the simulation mode for the ILS-LOC modulation signal. A change of the setting
automatically changes the sign of the DDM value.
Parameters:
<Direction> LEFT | RIGHt
LEFT
The 150 Hz modulation signal is predominant, the DDM value is
negative (the airplane is too far to the right, it must turn to the
left).
RIGHT
The 90 Hz modulation signal is predominant, the DDM value is
positive (the airplane is too far to the left, it must turn to the
right).
*RST: LEFT
Example: See Example "Configure and generate an ILS localizer signal"
on page 595.
Manual operation: See "Fly Mode" on page 156
[:SOURce<hw>]:ILS:LOCalizer:DDM:LOGarithmic <Logarithmic>
Sets the modulation depth in dB for ILS localizer modulation.
See also [:SOURce<hw>]:ILS:LOCalizer:DDM[:DEPTh] on page 617.
Parameters:
<Logarithmic> float
Range: -999.9 to 999.9
Increment: 1E-4
*RST: 0
Example: See Example "Configure and generate an ILS localizer signal"
on page 595.
Manual operation: See "DDM Logarithmic" on page 158
