get_coupling() → AvionicIlsDdmCoup

# [SOURce<HW>]:[BB]:ILS:LOCalizer:DDM:COUPling
value: enums.AvionicIlsDdmCoup = driver.source.bb.ils.localizer.ddm.get_coupling()

Selects if the DDM value is fixed or is changed with a change of sum of modulation depths (SDM, seemethod RsSmbv.source.bb.ils.localizer.sdm() ) .

Returns:

coupling: FIXed | SDM

get_current() → float

# [SOURce<HW>]:[BB]:ILS:LOCalizer:DDM:CURRent
value: float = driver.source.bb.ils.localizer.ddm.get_current()

Sets the DDM value alternatively as a current by means of the ILS indicating instrument. The instrument current is calculated according to: DDM uA = DDM x 857,1 uA A variation of the instrument current automatically leads to a variation of the DDM value and the DDM value in dB.

Returns:

current: float Range: -9.6775E-4 to 9.6775E-4

get_depth() → float

value: float = driver.source.bb.ils.localizer.ddm.get_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 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.

Returns:

depth: float Range: -0.4 to 0.4
