[:SOURce<hw>]:ILS:LOCalizer: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 mod-
ulation depths of the 90 Hz and the 150 Hz tone.The following is true:
ILS: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.
Parameters:
<Depth> float
Range: -0.4 to 0.4
Increment: 1E-4
*RST: 0
Example: See Example "Configure and generate an ILS localizer signal"
on page 595.
Manual operation: See "DDM Depth" on page 157
[:SOURce<hw>]:ILS:LOCalizer:FREQuency <CarrierFreq>
Sets the carrier frequency of the signal.
Parameters:
<CarrierFreq> float
Range: 100E3 to 6E9
Increment: 0.01
*RST: 108.1E6
Example: See Example "Configure and generate an ILS localizer signal"
on page 595.
Manual operation: See "Carrier Frequency" on page 152
[:SOURce<hw>]:ILS:LOCalizer:FREQuency:MODE <IlsLocFreqMode>
Sets the mode for the carrier frequency of the signal.
Parameters:
<Mode> DECimal | ICAO
DECimal
Activates user-defined variation of the carrier frequency.
ICAO
Activates variation in predefined steps according to standard ILS
transmitting frequencies (see Table 6-2).
*RST: DECimal
Example: See Example "Configure and generate an ILS localizer signal"
on page 595.
