STD
Activates the standard time schema of the Morse code.
The set dot length determines the dash length, which is 3
times the dot length.
USER
Activates the user-defined time schema of the Morse code.
Dot and dash length, as well as symbol and letter space
can be set separately.
*RST: STD
Example: See Example "Configure and generate an ILS localizer signal"
on page 595.
Manual operation: See "Time Schema" on page 160
[:SOURce<hw>]:ILS:LOCalizer:COMid[:STATe] <State>
Enables/disables the COM/ID signal.
Parameters:
<State> 1 | ON | 0 | OFF
*RST: 0
Example: See Example "Configure and generate an ILS localizer signal"
on page 595.
Manual operation: See "COM/ID State" on page 159
[:SOURce<hw>]:ILS:LOCalizer:DDM:COUPling <Coupling>
Selects if the DDM value is fixed or is changed with a change of sum of modulation
depths (SDM, see [:SOURce<hw>]:ILS:LOCalizer:SDM on page 620).
Parameters:
<Coupling> FIXed | SDM
*RST: FIXed
Example: See Example "Configure and generate an ILS localizer signal"
on page 595.
Manual operation: See "DDM - SDM Coupling" on page 157
[:SOURce<hw>]:ILS:LOCalizer:DDM:CURRent <Current>
Sets the DDM value alternatively as a current by means of the ILS indicating instru-
ment. The instrument current is calculated according to:
DDM µA = DDM × 857,1 µA
A variation of the instrument current automatically leads to a variation of the DDM
value and the DDM value in dB.
