[:SOURce<hw>]:ILS:LOCalizer:PHASe <Phase>
Sets the phase between the modulation signals of the left and right antenna lobe of the
ILS localizer signal.
The zero crossing of the right lobe (150Hz) signal serves as a reference. The angle
refers to the period of the signal of the right antenna lobe.
Parameters:
<Phase> float
Range: -60 to 120
Increment: 0.01
*RST: 0
Example: See Example "Configure and generate an ILS localizer signal"
on page 543.
Manual operation: See "Left/Right Phase" on page 138
[:SOURce<hw>]:ILS:LOCalizer:PRESet
Sets the parameters of the ILS localizer component to their default values (*RST val-
ues specified for the commands).
For other ILS preset commands, see [:SOURce<hw>]:ILS:PRESet on page 546.
Example:
SOURce1:ILS:LOCalizer:PRESet
Usage: Event
[:SOURce<hw>]:ILS:LOCalizer:RLOBe[:FREQuency] <Frequency>
Sets the modulation frequency of the antenna lobe arranged at the right viewed from
the air plane.
Parameters:
<Frequency> float
Range: 100 to 200
Increment: 0.05
*RST: 150
Example: See Example "Configure and generate an ILS localizer signal"
on page 543.
Manual operation: See "Right Frequency" on page 138
[:SOURce<hw>]:ILS:LOCalizer:SDM <Sdm>
Sets the arithmetic sum of the modulation depths of the left lobe (90 Hz) and right lobe
(150 Hz) for the ILS localizer signal contents.
The RMS modulation depth of the sum signal depends on the phase setting of both
modulation tones.
