[:SOURce]:ILS[:GS|GSLope]:DDM[:DEPTh] <Depth>
Sets the difference in depth of modulation between the signal of the upper/left lobe (90 Hz) and the lower/right lobe (150 Hz). The maximum value equals the sum of the modulation depths of the 90 Hz and the 150 Hz tone. The following applies:
ILS:GS|LOC:DDM:DEPTh = (AM(90Hz) - AM(150Hz))/100%
A variation of the DDM value automatically leads to a variation of the DDM value in dB and the value of the instrument current.
The setting range of DDM depends on the set
