Example: See Example "Configure and generate an ILS glide slope signal"
on page 594.
Manual operation: See "ICAO Channel" on page 146
[:SOURce<hw>]:ILS[:GS|GSLope]:LLOBe[:FREQuency] <Frequency>
Sets the modulation frequency of the antenna lobe arranged at the bottom viewed from
the air plane for the ILS glide slope modulation signal.
Parameters:
<Frequency> float
Range: 100 to 200
Increment: 0.05
*RST: 150
Example: See Example "Configure and generate an ILS glide slope signal"
on page 594.
Manual operation: See "Down Frequency" on page 148
[:SOURce<hw>]:ILS[:GS|GSLope]:MODE <Mode>
Sets the operating mode for the ILS glide slope modulation signal.
Parameters:
<Mode> NORM | ULOBe | LLOBe
NORM
ILS glide slope modulation is active.
ULOBe
Amplitude modulation of the output signal with the upper lobe
(90Hz) signal component of the ILS glide slope signal is active.
LLOBe
Amplitude modulation of the output signal with the lower lobe
(150Hz) signal component of the ILS glide slope signal is active.
*RST: NORM
Example: See Example "Configure and generate an ILS glide slope signal"
on page 594.
Manual operation: See "Operating Mode" on page 147
[:SOURce<hw>]:ILS[:GS|GSLope]:PHASe <Phase>
Sets the phase between the modulation signals of the upper and lower antenna lobe of
the ILS glide slope signal.
Zero crossing of the lower lobe (150Hz) signal serves as a reference. The angle refers
to the period of the signal of the right antenna lobe.
