DME defines frequency and depth of the two-tone signal that is superimposed to the pulse signal with amplitude modulation.
The following example shows a DME signal with a superimposed two-tone signal:
Access:
► | Select "Modulation > config... > DME > Composite AM". The "DME Composite AM" dialog provides the settings for a two-tone signal that can be superimposed on the DME pulses with amplitude modulation. This feature enables you to simulate the variation of the DME pulse amplitude for DME receiver testing. |
Activates the two-tone signal.
Remote command:Sets the modulation depth in %.
Note: Observe that this value is valid for both signals, and that the sum modulation depth is determined by doubling the set modulation depth. If the maximum value for the modulation depth is exceeded (see data sheet), overmodulation occurs.
Determines the modulation depth in % for one component of the two-tone signal.
Remote command:Sets the individual frequencies of the two-tone signal.
