this application note describes the operating principle of dme (distance measurement equipment) that is used for distance measurement in aviation. it also describes various test scenarios for the maintenance of a dme transponder. these tests require an r&s®sma100a signal generator with r&s®sma-k26 dme modulation option, and an r&s®nrp-z81 wideband power sensor.
