Foreword
This European Telecommunication Standard (ETS) has been produced by the Electromagnetic
compatibility and Radio spectrum Matters (ERM) Technical Committee of the European
Telecommunications Standards Institute (ETSI).
This ETS has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 83/189/EEC (as amended) laying down a procedure for the provision of
information in the field of technical standards and regulations.
This ETS, together with ETS 300 328 [1] or ETS 300 836-1 (see bibliography), is intended to become a
Harmonized Standard, the reference of which will be published in the Official Journal of the European
Communities referencing the Council Directive on the approximation of the laws of the Member States
relating to electromagnetic compatibility ("the EMC Directive") (89/336/EEC as amended).
Technical specifications relevant to the EMC Directive are given in annex A.

Date of adoption: 24 October 1997
Date of latest announcement of this ETS (doa): 28 February 1998
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 August 1998

1 Scope
This European Telecommunication Standard (ETS) covers the assessment of the 2,4 GHz wideband
transmission systems and HIgh PErformance Radio Local Area Network (HIPERLAN) equipment in
respect of ElectroMagnetic Compatibility (EMC).
This ETS specifies the applicable EMC tests, the method of measurements, the limits and the minimum
performance criteria for wideband data communication systems, such as plug-in radio devices, hand-
portable equipment, mobile and fixed stations, as specified in ETS 300 328 [1], HIPERLAN Type 1 as
specified in ETS 300 652 [2].
In addition to the technical specifications of this ETS, there may be published in the Official Journal of the
European Commission references to other Harmonized EMC Standards that apply to the products
covered by this ETS in their own right.
The environmental classification used in this ETS refers to the environment classification used in the
generic Standards EN 50081-1 [3], EN 50082-1 [4], except the vehicular environment class which refers to
ISO 7637, Parts 1 [5] and 2 [6].
The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus at
residential, commercial, light industrial and vehicular environment. The levels however, do not cover
extreme cases which may occur in any location but with low probability of occurrence.
Technical specifications related to the antenna port and emissions for the enclosure port of the equipment
are not included in this ETS. Such specific technical specifications are found in the relevant product
standard.
This ETS may not cover those cases where a potential source of interference which is producing
individually repeated transient phenomena or a continuous phenomena is permanently present, e.g. a
radar or broadcast site in the near vicinity. In such a case it may be necessary to use special protection
applied to either the source of interference or the interfered part or both.
Compliance of radio equipment to the requirements of this ETS does not signify compliance to any
requirements related to spectrum management or any requirement related to the use of the equipment
(licensing requirements).
Compliance to this ETS does not signify compliance to any safety requirements. Any observations of
equipment becoming dangerous or unsafe as a result of the application of the tests defined in this ETS
shall be recorded in the test report.
This ETS is based on the considerations and guidance given in ETR 238 [15].

4 Test conditions
4.1 General
The equipment shall be tested under conditions which are within the manufacturer's declared range of
humidity, temperature, and supply voltage and the actual values of these parameters shall be recorded in
the test report.
The radio equipment may take forms which may require special software and/or test fixtures. In all cases
the EUT shall be exercised in a manner representative of normal intended use. The test configuration
shall be recorded in the test report.
Equipment which requires connection to a host equipment to function shall use the test configuration as
defined by the manufacturer.
4.2 Arrangements for test signals at the input of the receiver
4.2.1 General requirements
The test signals required to establish a communications link shall be defined by the manufacturer.
The level of the test signal at the input of the receiver shall be at least 30 dB above the declared Maximum
Usable Sensitivity (MUS).
4.2.2 Normal test modulation
The modulated test signal shall represent normal intended use, and may contain data formatting, error
detection and correction information.
4.3 Arrangements for test signals at the output of the receiver
It shall be possible to assess the performance of the equipment by appropriately monitoring the receiver
output.
4.4 Arrangements for test signals at the input of the transmitter
4.4.1 General requirements
The test signals and/or controls required to establish a communications link shall be defined by the
manufacturer. The transmitter shall be operated at maximum rated power.
4.4.2 Normal test modulation
The modulated test signal shall represent normal intended use, and may contain data formatting, error
detection and correction information.
4.5 Arrangements for test signals at the output of the transmitter
The measuring equipment used to monitor the output signal of the transmitter shall be located outside the
test environment. Adequate measures shall be taken to protect the measuring equipment from the effect
of all the radiated fields within the test environment.
The manufacturer may provide a suitable companion receiver that can be used to receive messages or to
set up a communication link.
Where the transmitter incorporates an external Radio Frequency (RF) antenna connector, the output
signal of the transmitter, shall be coupled to the receiving/measuring equipment via a shielded
transmission line such as a coaxial cable. Adequate measures shall be taken to minimize the effect of
unwanted common mode currents on the external conductor of the transmission line at its point of entry to
the transmitter.

---------------------- Page: 12 ----------------------

SIST ETS 300 826:2000
Page 11
ETS 300 826: November 1997
In case of an equipment not provided with an external RF connector, the output signal of the transmitter
shall be coupled to another antenna located within the test environment. This antenna shall be coupled to
the receiving/measuring equipment outside the test environment.
4.6 Narrow band responses of receivers
Responses of receivers occurring during the test at discrete frequencies which are narrow band
responses (spurious responses) are identified by the following method.
If during the test the unwanted signal causes non compliance of the receiver with the specified
performance level (see subclause 6.5), it is necessary to establish whether this non compliance is due to
a narrow band response or to a wideband phenomenon. Therefore, the unwanted signal frequency is
increased by an amount equal to twice the nominal bandwidth of the receiver pre-demodulation filter, as
declared by the manufacturer. The test is repeated with the frequency of the unwanted signal decreased
by the same amount.
If the receiver is then in compliance with the specified performance level (see subclause 6.5), the
response is considered as a narrow band response.
If the receiver still does not comply with the specified performance level (see subclause 6.5), this may be
due to the fact that the offset has made the frequency of the unwanted signal correspond to the frequency
of another narrowband response. Under these circumstances the procedure is repeated with the increase
and decrease of the frequency of the unwanted signal adjusted two and a half times the bandwidth
previously referred to. If the receiver still does not comply with the specified performance level, the
phenomena is considered wideband and therefore an EMC problem and the equipment fails the test.
Narrow band responses shall be disregarded.
5 Performance assessment

The manufacturer shall supply the following information which shall be recorded in the test report:
a) the operating frequency range(s) of the equipment and, where applicable, band(s) of operation;
