The present document specifies technical characteristics and methods of measurement in respect of ElectroMagnetic 
Compatibility (EMC) for the following equipment: 
• Secondary Surveillance Radar (SSR) interrogator; 
• SSR Far Field Monitor (FFM); 
• Multilateration (MLAT); 
• Wide Area Multilateration (WAM); 
• Distance Measurement Equipment (DME) land station transponder; 
• Extended Squitter (ES) / Non Transponder (NT). 
operating in the frequency range 960 MHz to 1 215 MHz. 
The above mentioned radio equipment can be intended for use at a fixed location or mobile use. 
The standard covers equipment consisting of one or more enclosures that contain at least one of the following 
functionalities: transmitter, receiver, signal processing. Other parts which are not part of the navigation functionality 
e.g. local UPS, air conditioning equipment, dehumidifying equipment, communication network equipment, etc., are not 
in the scope of the present document, unless these parts are implemented inside the system enclosure(s). 
NOTE 1: The relationship between the present document and essential requirements of article 3.1(b) of 
Directive 2014/53/EU [i.1] is given in annex A. 
Technical specifications related to conducted emission EMC requirements below 9 kHz on the AC mains port of radio 
equipment are not included in the present document. 
NOTE 2: Such technical specifications are normally found in the relevant product family standards for AC mains 
powered equipment (e.g. EN 61000-3-2 [i.3] and EN 61000-3-3 [i.4])
