Aviation RF Link Calculator

The program Aviation RF Link allows quick calculation of the forward link from a ground station to an aircraft. Based on the RF power of the ground station, the tool calculates the distance with a given field strength to be achieved at the aircraft antenna or calculates the field strength at a given power and…

Aeronautical radio navigation measurement solutions

This application note highlights various aeronautical radio navigation signals such as VHF omnidirectional radio range (VOR), instrument landing system (ILS) for glide slope (GS) and localizer (LLZ), as well as marker beacon (MB).  R&S® test and measurement solutions for avionics navigation equipment are introduced based on application scenarios, including calibration, research and development, field tests and…

Analyze your TACAN and DME ground equipment

The R&S®EDST300 is a flexible, compact and easy-to-use solution to carry out test cases in line with civil and military standards with a single instrument. Some measurements such as dead time, recovery time and echo suppression require a second signal source. With the R&S®SMBV100A vector signal generator, full test cases as required for DME and…

Test of DME/TACAN Transponders

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 a R&S® SMA-K26 DME modulation option and a R&S® NRP-Z81 Wideband Power Sensor.
