Selects the operating mode for the ILS-GS modulation signal.
Parameters: | ||||
<Mode> | NORM ILS-GS modulation is active. ULOBeAmplitude modulation of the output signal with the upper lobe (90Hz) signal component of the ILS-GS signal is active. The modulation depth of the 90Hz signal results from the settings of commands SOURce:ILS:GS:SDM and SOURce:ILS:GS:DDM[:DEPTh] according to (command SOURce:ILS:GS:DDM:DIR UP): AM(90Hz) = 0.5 * (ILS:GS:SDM + ILS:GS:DDM * 100%) and for SOURce:ILS:GS:DDM:DIR DOWN according to AM(90Hz) = 0.5 * (ILS:GS:SDM - ILS:GS:DDM * 100%) LLOBeAmplitude modulation of the output signal with the lower lobe (150Hz) signal component of the ILS-GS signal is active. The modulation depth of the 150Hz signal results from the settings of commands SOURce:ILS:GS:SDM and SOURce:ILS:GS:DDM[:DEPTh] according to (command SOURce:ILS:GS:DDM:DIR UP): AM(150Hz) = 0.5 * (ILS:GS:SDM + ILS:GS:DDM * 100%) and for SOURce:ILS:GS:DDM:DIR DOWN according to AM(150Hz) = 0.5 * (ILS:GS:SDM - ILS:GS:DDM * 100%)
