Using Avionics VOR/ILS Softkeys for N5171B/72B and N5181B/82B with Option 302
Using ILS Glide Slope Softkeys
4. Select a <value> from 0 to 10.0 uA and press Enter.
These softkeys set a value for the difference in depth of modulation (DDM)
in uA.
To set the ILS Glide Slope DDM value in percentage (%)
1. Press Aux Fctn > Avionics > ILS Glide Slope
2. Press DDM/SDM
3. Press DDM%
(Default <value> is 0.00%.)
4. Select a <value> from 0 - 99% and press Enter.
These softkeys set a value for the difference in depth of modulation (DDM)
in %. DDM can be expressed either in terms of percentage (%) or as a
modulation index. A DDM of 1% is equivalent to 0.001 DDM.
To set the ILS Glide Slope SDM value
1. Press Aux Fctn > Avionics > ILS Glide Slope
2. Press DDM/SDM
3. Press SDM
4. Select a <value> from 0 to 99% and press Enter.
(Default <value> is 80%.)
These softkeys set the sum of depth of modulation (SDM):
SDM = [AM(90 Hz) + AM(150 Hz)] / 100
