Foreword
This European Telecommunication Standard (ETS) has been produced by the European
Telecommunications Standards Institute (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 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.
This ETS consists of 3 parts as follows:
Part 1: "Mobile and portable radio and ancillary equipment";
Part 2: "Base station radio and ancillary equipment (Phase 1)" (RE/RES-09035-2);
Part 3: "Base station radio and ancillary equipment (Phase 2)" (DE/RES-09035-3).

1 Scope
This second edition European Telecommunication Standard (ETS) covers the assessment of radio
communication and ancillary equipment in respect of ElectroMagnetic Compatibility (EMC).
Technical specifications related to the antenna port and emissions from the enclosure port of radio
equipment are found in the related product standards for the effective use of the radio spectrum.
This ETS specifies the applicable EMC tests, the methods of measurement, the frequency range, the
limits and the minimum performance criteria for Phase 1 and Phase 2 GSM 900 MHz and DCS
1 800 MHz digital public cellular mobile and portable radio equipment, transmitting and receiving speech
and/or data, and the associated ancillary equipment.
Base station equipment operating within network infrastructure is outside the scope of this ETS. However,
this ETS does cover mobile and portable equipment that is intended to be operated in a fixed location
while connected to the AC mains.
The environment classification used in this ETS refers to the environment classification used in the
Generic Standards EN 50081-1 [1], EN 50082-1 [2], except the vehicular environment class which refers
to ISO 7637 Part 1 [3] and Part 2 [4].
For the purposes of this ETS, Mobile Stations (MS) are considered to be radio communications
equipment.
The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus in
residential, commercial, light industrial and vehicular environments. The levels however, do not cover
extreme cases which may occur in any location but with low probability of occurrence.
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
requirement related to the use of the equipment (i.e. licensing requirements).
Compliance to this ETS does not signify compliance to any safety requirement. However, it is the
responsibility of the assessor of the equipment that any observation regarding the equipment becoming
dangerous or unsafe as a result of the application of the tests of this ETS, should be recorded in the test
report.

4 General test conditions
This clause defines the general test configuration and is relevant to clauses 8 and 9.
4.1 Test conditions and configurations
This subclause defines the configurations for emission and immunity tests as follows:
- the equipment shall be tested under normal test conditions as specified in the product standard;
- the test configuration shall be as close to normal intended use as possible;
- if the equipment is part of a system, or can be connected to ancillary equipment, then it shall be
acceptable to test the equipment while connected to the minimum configuration of ancillary
equipment necessary to exercise the ports;
- if the equipment has a large number of ports, then a sufficient number shall be selected to simulate
actual operation conditions and to ensure that all the different types of termination are tested;
- the test conditions, test configuration and mode of operation shall be recorded in the test report;
- where portable (handheld) equipment is provided with a detachable integral antenna, it shall be
tested with the antenna fitted in a manner typical of normal intended use, unless specified otherwise
in this ETS;
- ports which in normal operation are connected shall be connected to an ancillary equipment or to a
representative piece of cable correctly terminated to simulate the input/output characteristics of the
ancillary equipment, Radio Frequency (RF) input/output ports shall be correctly terminated;
- ports which are not connected to cables during normal operation, e.g. service connectors,
programming connectors, temporary connectors etc. shall not be connected to any cables for the
purpose of EMC testing. Where cables have to be connected to these ports, or interconnecting
cables have to be extended in length in order to exercise the EUT, precautions shall be taken to
ensure that the evaluation of the EUT is not affected by the addition or extension of these cables;
- the test arrangements for transmitters and receivers are described separately for the sake of clarity.
However, where possible the test of the transmitter section and receiver section of the EUT may be
carried out simultaneously to reduce test time.
4.2 Emission measurements
This subclause defines the test conditions and configurations for the emission tests as follows:
- the measurement shall be made in the operational mode producing the largest emission in the
frequency band being investigated consistent with normal applications;
- an attempt shall be made to maximize the detected radiated emission for example by moving the
cables of the equipment.
4.3 Immunity tests
For the immunity tests of transmitters, the transmitter shall be operated at its maximum rated output
power, modulated with normal test modulation, and a communication link shall be established
(subclauses 4.4, 4.5 and 4.6).
For the immunity tests of receivers, the wanted input signal, coupled to the receiver, shall be modulated
with normal test modulation, and a communication link shall be established (subclauses 4.4, 4.7 and 4.8).
For the immunity tests of duplex transceivers, the wanted input signal, coupled to the receiver, shall be
modulated with normal test modulation, the transmitter shall be operated at its maximum rated output
power and shall be modulated with normal test modulation, and a communication link shall be established
(subclauses 4.4, 4.5, 4.6, 4.7 and 4.8).

Page 11
ETS 300 342-1: June 1997
4.4 Normal test modulation
The wanted RF input signal nominal frequency shall be selected by setting the Absolute Radio Frequency
Channel Number (ARFCN) to an appropriate number, e.g. in the case of GSM 900 MHz this is 60 to 65.
A communication link shall be set up with a suitable base station, system simulator, or production mobile
tester (hereafter called "the test system").
When the EUT is required to be in the transmit/receive mode, the following conditions shall be met:
- the EUT shall be commanded to operate at maximum transmit power;
- the downlink RXQUAL shall be monitored;
- prior to the test sequence, the reference level of the speech output signal on both the downlink and
uplink shall be recorded on the test instrumentation, as shown in figure 2. The reference level shall
be equivalent to 0 dBPa at 1 kHz at the Ear Reference Point (ERP) for the downlink, and -5 dBPa at
1 kHz at the Mouth Reference Point (MRP) for the uplink. Set the EUT volume to provide nominal
audio level if specified by the manufacturer. If no such level is specified, the centre volume step
shall be used;
- the level of the output signal from the EUT's downlink speech channel at the mobile or portable's
ear piece shall be assessed by measuring the Sound Pressure Level (SPL) as shown in figure 1;
- the level of the decoded output signal from the EUT's uplink speech channel at the analogue output
of the test system shall be measured. Pick up of extraneous background noise by the EUT's
microphone shall be minimized.
NOTE: In the case of equipment not containing analogue speech circuits, the assessment of
speech signal level is not applicable.

4.5 Arrangements for test signals at the input of the transmitter
For mobiles and portables the test system shall command the EUT to disable Discontinuous Transmission
(DTX).
A communication link shall be set up between the EUT and the test system.
4.6 Arrangements for test signals at the output of the transmitter
The test system shall be located outside of the test environment.
Where the equipment incorporates an external 50 Ω RF antenna connector that is normally connected via
a coaxial cable, then the wanted signal to establish a communication link shall be delivered from that
connector by a coaxial cable. Adequate measures shall be taken to avoid the effect of the unwanted signal
on the measuring equipment.
Where the equipment incorporates an external 50 Ω RF antenna connector but this port is not normally
connected via a coaxial cable, then the wanted signal to establish a communication link shall be delivered
from that connector by a coaxial cable. Adequate measures shall be taken to avoid the effect of unwanted
currents on the external conductor of the coaxial cable at the point of entry to the equipment. Adequate
measures shall also be taken to avoid the effect of the unwanted signal on the measuring equipment.
Where the equipment does not incorporate an external 50 Ω RF connector (integral antenna equipment),
the wanted signal, to establish a communication link, shall be delivered from the equipment to an antenna
located within the test environment. Adequate measures shall be taken to avoid the effect of the unwanted
signal on the measuring equipment.
4.7 Arrangements for test signals at the input of the receiver
The test system shall be located outside of the test environment.
Where the equipment incorporates an external 50 Ω RF antenna connector that is normally connected via
a coaxial cable, then the wanted signal to establish a communication link shall be delivered to that
connector by a coaxial cable. Adequate measures shall be taken to avoid the effect of the unwanted signal
on the measuring equipment. The source of the wanted input signal shall be located outside of the test
environment. The wanted input signal level shall be set at a nominal value of 66 dBμV emf.

Page 13
ETS 300 342-1: June 1997
Where the equipment incorporates an external 50 Ω RF antenna connector, but this port is not normally
connected via a coaxial cable, then the wanted signal to establish a communication link shall be delivered

currents on the external conductor of the coaxial cable at the point of entry to the equipment. Adequate
measures shall also be taken to avoid the effect of the unwanted signal on the measuring equipment. The
source of the wanted input signal shall be located outside of the test environment. The wanted input signal
level shall be set at a nominal value of 66 dBμV emf.
Where the equipment does not incorporate an external 50 Ω RF connector (integral antenna equipment),
the wanted signal, to establish a communication link, shall be presented to the equipment from an
antenna located within the test environment. The source of the wanted input signal shall be located
outside of the test environment. The wanted input signal level shall be set at a nominal value of 90 dBμV
emf.
4.8 Arrangements for test signals at the output of the receiver
The audio frequency output of the equipment may be coupled via a non-metallic acoustic tube to a
suitable audio level meter outside of the test environment.
Other means of connecting the receiver output to a suitable audio level meter may be provided but shall
be recorded in the test report. Precautions shall be taken to ensure that any effect on the test is
minimized.
4.9 Receiver and duplex transceiver exclusion band
The exclusion band for receivers and the receivers of transceivers is the band of frequencies over which
no radiated immunity tests are made.
The lower frequency of the exclusion band is the lower frequency of the receive band of the EUT minus
6 %.
The upper frequency of the exclusion band is the upper frequency of the receive band of the EUT plus
5 %.
4.10 Transmitter exclusion band
The exclusion band for transmitters extends three times the channel separation (3 × 200 kHz = 600 kHz)
centred on the nominal operating frequency of the transmitter.
4.11 Narrow band responses on receivers and duplex transceivers
Responses on receivers or duplex transceivers occurring during the test at discrete frequencies which are
narrow band responses (spurious responses), are identified by the following method:
- if during an immunity test the RXQUAL or speech output signal level being monitored goes outside
the specified figure, it is necessary to establish whether the RXQUAL increase or speech output
signal level increase is due to a narrow band response or to a wide band phenomenon. Therefore,
the test shall be repeated with the unwanted signal frequency increased, and then decreased by
400 kHz;
- if the RXQUAL increase or speech output signal level increase disappears in either or both of the
above 400 kHz offset cases, then the response is considered as a narrow band response;
- if the RXQUAL increase or speech output signal level increase does not disappear, this may be due
to the fact that the offset has made the frequency of the unwanted signal correspond to the
frequency of another narrow band response. Under these circumstances the procedure is repeated
with the increase and decrease of the frequency of the unwanted signal set to 500 kHz;
- if the RXQUAL increase or speech output signal level increase still does not disappear with the
increased and/or decreased frequency, the phenomena is considered wide band and therefore an
EMC problem and the equipment fails the test.

Page 14
ETS 300 342-1: June 1997
Narrow band responses are disregarded.
4.12 Idle Mode
When the EUT is required to be in the idle mode, the test system shall simulate a Base Station (BS) with
Broadcast Control Channel/Common Control Channel (BCCH/CCCH) on one carrier. The EUT shall be
synchronized to the BCCH, listening to the CCCH and able to respond to paging messages.
5 Performance assessment

case of mobiles and portables the assessment of audio breakthrough by monitoring speech output signal
level, are used as the performance criteria to ensure that all the primary functions of the transmitter and
receiver are evaluated during the immunity tests. In addition, the test shall also be performed in idle mode
for transceivers or standby mode for transmitters only, to ensure the transmitter does not unintentionally
operate.
The maintenance of a communications link shall be assessed by using an indicator which may be part of
the test system or the equipment under test.
Specifically the equipment shall meet the minimum performance criteria as specified in the following
subclauses as appropriate.
Portable equipment intended for use whilst powered by the main battery of a vehicle shall additionally fulfil
the applicable requirements set out by this ETS for vehicular mobile equipment.
Portable or mobile equipment intended for use whilst powered by AC mains shall additionally fulfil the
applicable requirements of this ETS for base station equipment, although the input/output arrangements
of the equipment and the performance criteria may remain unchanged if this is more appropriate.
If an equipment is of a specialized nature, such that the performance criteria described in the following
subclauses are not appropriate, then the manufacturer shall declare, for inclusion in the test report, his
own specification for an acceptable level of performance or degradation of performance during and/or
after testing, as required by this ETS. The performance specification shall be included in the product
description and documentation.
6.1 Performance criteria for Continuous phenomena applied to Transmitters (CT)
A communication link shall be established at the start of the test, and maintained during the test,
subclauses 4.5, 4.6, 4.7 and 4.8.
For mobiles and portables, the uplink and downlink speech output levels shall be at least 35 + dB less
than the previously recorded reference levels, when measured through an audio band pass filter of width
200 + Hz, centred on 1 kHz.
At the conclusion of the test the EUT shall operate as intended with no loss of user control functions or
stored data, and the communication link shall have been maintained. Where the EUT is a mobile or
portable, in addition to confirming the above performance during a call, the test shall also be performed in
idle mode, and the transmitter shall not unintentionally operate.
Where the EUT is a transmitter only, tests shall be performed with the EUT in standby mode to ensure
that unintentional transmission does not occur.
6.2 Performance criteria for Transient phenomena applied to Transmitters (TT)
A communications link shall be established at the start of the test, subclauses 4.5, 4.6, 4.7 and 4.8.
At the conclusion of each exposure the EUT shall operate with no user noticeable loss of the
communication link.

ETS 300 342-1: June 1997
At the conclusion of the total test comprising the series of individual exposures the EUT shall operate as
intended with no loss of user control functions or stored data, as declared by the manufacturer, and the
communication link shall have been maintained.
In addition to confirming the above performance during a call, the test shall also be performed in idle
mode, and the transmitter shall not unintentionally operate.
Where the EUT is a transmitter only, tests shall be performed with the EUT in standby mode to ensure
that unintentional transmission does not occur.
6.3 Performance criteria for Continuous phenomena applied to Receivers (CR)
A communications link shall be established at the start of the test, and maintained during the test,
subclauses 4.5, 4.6, 4.7 and 4.8.
For mobiles and portables RXQUAL of the downlink shall not exceed three, measured during each
individual exposure in the test sequence.
For mobiles and portables, the uplink and downlink speech output levels shall be at least 35 dB less than
the previously recorded reference levels, when measured through an audio band pass filter of width
200 + Hz, centred on 1 kHz.
At the conclusion of the test the EUT shall operate as intended with no loss of user control functions or
stored data, and the communication link shall have been maintained.
6.4 Performance criteria for Transient phenomena applied to Receivers (TR)
A communications link shall be established at the start of the test, subclauses 4.5, 4.6, 4.7 and 4.8.
At the conclusion of each exposure the EUT shall operate with no user noticeable loss of the
communication link.
At the conclusion of the total test comprising the series of individual exposures, the EUT shall operate as
intended with no loss of user control functions or stored data, as declared by the manufacturer, and the
communication link shall have been maintained.
