[:SOURce]:DME:RDIStance <RDistance>

Sets the simulated distance between interrogator and transponder for reply mode. The distance is given in nautic miles (nm). 1 nm is 1852.01 meters and corresponds to a run time of 12.359 µs. This command is available for reply mode only.

The range distance and the external trigger delay are interdependent according to:

range distance = (trigger delay – X/Y mode delay)/12.359 µs/nm

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

Changing one value automatically changes the other value.

Parameters:
<RDistance>
float
Range: -4.046 (X), -4.531 (Y)  to  400
Increment: 0.001 nm
*RST:0 nm
Default unit: nm
Example: DME:MODE REPL

selects reply mode

DME:RDIS 0.1 nm

sets a range distance of 0.1 nautic mile

Options: Option R&S SMA-K26
Manual operation: See "Range Distance - DME Modulation"
