*RST: LEFT
Example: See Example "Configure and generate an ILS localizer signal"
on page 543.
Manual operation: See "FlyMode" on page 139
[: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 565.
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 543.
Manual operation: See "DDM Logarithmic" on page 141
[:SOURce<hw>]:ILS:LOCalizer:DDM:PCT <Pct>
Sets the difference in depth of modulation between the signal of the left lobe (90 Hz)
and the right lobe (150 Hz). The maximum value equals the sum of the modulation
depths of the 90 Hz and the 150 Hz tone.
See also [:SOURce<hw>]:ILS:LOCalizer:DDM[:DEPTh] on page 565.
Parameters:
<Pct> float
Range: -80.0 to 80.0
Increment: 0.01
*RST: 0
Example: See Example "Configure and generate an ILS localizer signal"
on page 543.
Manual operation: See "DDM Percent" on page 141
[:SOURce<hw>]:ILS:LOCalizer:DDM:POLarity <Polarity>
Sets the polarity for DDM calculation (see [:SOURce<hw>]:ILS:LOCalizer:DDM[:
DEPTh]).
The DDM depth calculation depends on the selected polarity:
●
Polarity 90 Hz - 150 Hz (default setting):
DDM = [ AM (90 Hz) - AM (150 Hz) ] / 100%
●
Polarity 150 Hz - 90 Hz:
