Selects the mode of the DME modulation. The mode determines the signal type that is simulated. The exact timing of the signal for each mode is determined by the selected channel (X or Y, SOURce:DME:CSUFfix).
Parameters: | ||||
<Mode> | INTerrogation The interrogation signal of the airborne transmitter is simulated. REPLyThe reply signal of the ground based transponder is simulated. The trigger is automatically set to external and the default trigger delay either to 50 us (channel X) or 56 us (channel Y) depending on the selected channel (SOURce:DME:CSUFFix). The interval between the pulse pairs can be set to a fixed value (repetition rate, SOURce:DME:RATE) or to random generation (pulse squitter, SOURce:DME:SQUitter). The trigger signal is input via the PULSE EXT connector.
