[:SOURce]:ILS:LOCalizer:MODE <Mode>

Selects the operating mode for the ILS-LOC modulation signal.

Parameters:
<Mode>
NORM| LLOBe| RLOBe
NORM

ILS-LOC modulation is active.

LLOBe

Amplitude modulation of the output signal with the left lobe (90Hz) signal component of the ILS-LOC signal is active. The modulation depth of the 90Hz signal results from the settings of commands SOURce:ILS:LOC:SDM and SOURce:ILS:LOC:DDM[:DEPTh] according to (command SOURce:ILS:LOC:DDM:DIR RIGHt):

AM(90Hz) = 0.5 * (ILS:LOC:SDM + ILS:LOC:DDM * 100%)

and for SOURce:ILS:GS:DDM:DIR LEFT according to

AM(90Hz) = 0.5 * (ILS:LOC:SDM - ILS:LOC:DDM * 100%)

RLOBe

Amplitude modulation of the output signal with the right lobe (150Hz) signal component of the ILS-LOC signal is active. The modulation depth of the 150Hz signal results from the settings of commands SOURce:ILS:LOC:SDM and SOURce:ILS:LOC:DDM[:DEPTh] according to (command SOURce:ILS:LOC:DDM:DIR RIGHt):

AM(150Hz) = 0.5 * (ILS:LOC:SDM + ILS:LOC:DDM * 100%)

and for SOURce:ILS:GS:DDM:DIR LEFT according to

AM(150Hz) = 0.5 * (ILS:LOC:SDM - ILS:LOC:DDM * 100%)

*RST:NORM
Example: ILS:LOC:MODE LLOB

Activates amplitude modulation of the output signal with the left lobe (90Hz) signal component of the ILS-LOC signal.

Options: Option R&S SMA-K25
Manual operation: See "Mode - ILS-LOC Modulation"
