get_coupling() → RsSmbv.enums.AvionicIlsDdmCoup[source]

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

Selects if the DDM value is fixed or is changed with a change of sum of modulation depths (SDM, see [:SOURce<hw>][:BB]:ILS[:GS|GSLope]:SDM) .

return

coupling: FIXed| SDM

get_current() → float[source]

# SCPI: [SOURce<HW>]:[BB]:ILS:[GS]:DDM:CURRent
value: float = driver.source.bb.ils.gs.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 Current uA = DDM Depth [%] x 857,125 uA A variation of the instrument current automatically leads to a variation of the DDM value and the DDM value in dB.

return

current: float Range: -8.57125E-4 to 8.57125E-4

get_depth() → float[source]

# SCPI: [SOURce<HW>]:[BB]:ILS:[GS]:DDM:[DEPTh]
value: float = driver.source.bb.ils.gs.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:GS|GSL: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.

return

depth: float Range: -0.8 to 0.8

value: enums.UpDownDirection = driver.source.bb.ils.gs.ddm.get_direction()

Sets the simulation mode for the ILS glide slope modulation signal. A change of the setting automatically changes the sign of the DDM value.

return

direction: UP| DOWN UP The 150 Hz modulation signal is predominant, the DDM value is negative (the airplane is too low, it must climb) . DOWN The 90 Hz modulation signal is predominant, the DDM value is positive (the airplane is too high, it must descend) .
