1 Scope
The present document, together with ETSI EN 301 489-1 [1], covers the assessment of Mobile Earth Stations (MES) as
defined in annex B used within Satellite radio services, and ancillary equipment in respect of ElectroMagnetic
Compatibility (EMC).
Technical specifications related to the antenna port and emissions from the enclosure port of the equipment are not
included in the present document. Such technical specifications are found in the relevant product standards for the
effective use of the radio spectrum.
The present document specifies the applicable test conditions, performance assessment and performance criteria for
MESs and for the associated ancillary equipment.
In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present
document and ETSI EN 301 489-1 [1], the provisions of the present document take precedence.
The environmental classification and the emission and immunity requirements used in the present document are as
stated in ETSI EN 301 489-1 [1], except for any special conditions included in the present document. The applicable
environment(s) referred to in ETSI EN 301 489-1 [1] where the MES may be used, should be declared by the
manufacturer.
For a multimode radio station, the present document only applies to the radio station when operated in the Mobile
Satellite Service mode.
NOTE: 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.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in ETSI EN 301 489-1 [1] and the following
apply:
carrier-on state (allocated a channel): state of an MES when it is transmitting a signal in a continuous or a
non-continuous mode
carrier-off state (idle mode): state of an MES when it is powered-on but not transmitting a signal, i.e. not in a
carrier-on state
host equipment: any equipment which has complete user functionality when not connected to the MES, and to which
connection is necessary for the MES to offer additional functionality
Installable Equipment (IE), Internally Mounted Equipment (IME) and Externally Mounted Equipment (EME):
equipment which is intended to be installed in a vehicle
NOTE: An IE may consist of one or several modules. The IE is composed of modules intended to be externally
mounted and declared by the manufacturer as Externally Mounted Equipment (EME). The remaining
module(s) are defined as Internally Mounted Equipment (IME).
multimode MES: equipment that accommodates radio stations of different radio systems
occupied bandwidth: See ITU-R Radio Regulations [2], part A, chapter 1, Terminology RR 147.
Portable Equipment (PE): equipment generally intended to be self-contained, free standing and portable
NOTE 1: A PE would normally consist of a single module, but may consist of several interconnected modules.
NOTE 2: More than one of the equipment classifications can apply to certain equipment, as described in clause 5.4,
dependent upon the manufacturer's declaration of normal intended use.
transmission disabled state: state of an MES when it is not authorized to transmit by the Network Control
Facilities (NCF)

4 Test conditions
4.1 General
For the purposes of the present document, the test conditions of ETSI EN 301 489-1 [1], clause 4, shall apply as
appropriate. Further product related test conditions for MES are specified in the present document.
For MESs with ancillary equipment and/or various ports, the number of test configurations shall be determined. The
assessment shall include sufficient representative configurations of the MES to adequately exercise the equipment.
These configurations shall be recorded in the test report.
In the following clauses, the Equipment Under Test (EUT) is the MES with the selected configuration of ancillary
equipment.
The EUT operational frequencies used during the test, shall be recorded in the test report.
For testing and if physically separated from the MES, any voltage converter shall form part of the EUT.
Whenever the Equipment Under Test (EUT) is provided with an integral antenna, the EUT shall be tested with the
antenna fitted in a manner typical of normal intended use.
For MES for which connection to a host equipment is necessary to offer additional functionality, the test configuration
shall be as defined in clause 5.2.
