[:SOURce]:DME:TRIGger:DELay <Delay>

Sets the delay between the external trigger and the first DME output pulse (50% voltage point of first pulse). This command is effective for external trigger only.

For DME Reply mode this simulates the defined delay of the DME transponder and twice the run time of the signal (from interrogator to transponder and back). The delay is a measure of the range distance, thus, the two values are interdependent according to:

Delay = X/Y mode delay + range distance * 12.359 nm/µs

(X mode delay = 50 µs, Y mode delay is 56 µs)

Changing one value automatically changes the other value.

Parameters:
<Delay>
float
Range: 4 us  to  5 ms
Increment: 20 ns
*RST:Reply X: 50 µs | Reply Y: 56 µs | Interrogation: 50 µs
Example: DME:TRIG EXT

activates external trigger mode

DME:TRIG:DEL 150us

sets a delay of 150us

Options: Option R&S SMA-K26
Manual operation: See "Trigger Delay - DME Modulation"
