Remote Control Commands > SOURce Subsystem > SOURce:ILS Subsystem > [:SOURce]:ILS[:GS|GSLope]:SDM
[:SOURce]:ILS[:GS|GSLope]:SDM <Sdm>
[:SOURce]:ILS:LOCalizer:SDM <Sdm>

The commands enter the arithmetic sum of the modulation depths of the upper/left lobe (90Hz) and lower/right lobe (150Hz) ILS-GS/ILS-LOC signal contents. The RMS modulation depth of the sum signal depends on the phase setting of both modulation tones.

Note:

Commands [SOURce:]ILS[:GS|GSLope]:SODepth and [SOURce:]ILS:LOCalizer:SODepth are implemented as alias commands.

Parameters:
<LocSdm>
float
Range: 0  to  100
Increment: 0.1
*RST:40
Default unit: PCT
<GsSdm>
float
Range: 0  to  100
Increment: 0.1
*RST:80
Default unit: PCT
Example: ILS:SDM 80PCT

sets a sum of modulation depths of 80 % for the upper lobe (90Hz) and lower lobe (150Hz) ILS-GS signal.

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