Foreword
This European Telecommunication Standard (ETS) has been produced by the Electromagnetic
compatibility and Radio spectrum Matters (ERM) Technical Committee of the European
Telecommunications 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.
For equipment within the scope of ETS 300 719-1 [15], this ETS, together with ETS 300 719-1 [15], 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).
For other equipment, 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 C.

1 Scope
This European Telecommunication Standard (ETS) covers the assessment of wide-area paging
equipment and ancillary equipment, in respect of ElectroMagnetic Compatibility (EMC). Technical
specifications related to the antenna port and emissions from the enclosure port of the wide-area paging
equipment are not included in this ETS.
This ETS does not cover ERMES paging receiver equipment.
This ETS specifies the applicable EMC tests, the method of measurements, the limits and the minimum
performance criteria for wide-area paging equipment.
The environment classification used in this ETS refers to the environment classification used in
EN 50081-1 [1], EN 50082-1 [2].
The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus at
residential, commercial and light industrial 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 wide-area paging 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. 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 Test conditions
4.1 General
The tests shall be carried out at a point within the specified normal operating environmental range and at
the rated supply voltage for the equipment. The test conditions shall be recorded in the test report.
The test configuration and mode of operation shall be as close to normal intended use as possible and
shall be recorded in the test report.
For immunity tests the test modulation, test arrangements etc., as specified in this ETS in subclauses 4.2
to 4.8 shall apply and the conditions shall be as follows:
- the base transmitter shall operate in the standby mode, except for the radio frequency immunity test
(see subclause 9.2) where the transmitter shall be tested additionally at its maximum rated output
power, modulated with normal test modulation (see subclause 4.2);
- for pocket receivers, the message memory of the receiver memory shall be loaded with
recognisable messages. The receiver shall operate in the standby mode, except for the spot
frequency test of the radio frequency immunity test (see subclause 9.2) where repetitive calls shall
be coupled to the input of the receiver.
4.2 Normal test modulation
The test modulation signal to be used for the calling function shall represent selective messages and
maybe generated by a signal generator or encoded within the equipment. The signal generator used
should be a test signal generator supplied by the manufacturer and capable of generating repetitive calls.
4.3 Arrangements for test signals at the input of the base transmitter
The signal generator to be used for the normal test modulation (see subclause 4.2) shall be located
outside the test environment and connected to the modulation input port of the transmitter. Adequate
measures shall be taken to protect the measuring equipment from the effect of all of the radiated fields
within the test environment.
4.4 Arrangements for test signals at the output of the base transmitter
The output signal shall be delivered from the RF antenna connector by a shielded transmission line, such
as a coaxial cable, to the receiving/measuring equipment outside of the test environment.
Adequate measures shall be taken to avoid the effect of unwanted signals on the measuring equipment.
For the spot frequency test of the radio frequency immunity test (see subclause 9.2) repetitive calls shall
be transmitted and coupled to the input of the measuring equipment located outside the test environment.
The measuring equipment should be a paging receiver.
4.5 Arrangements for test signals at the input of the pocket receiver
The manufacturer shall at the time of submitting the equipment for testing, supply, if necessary, a test
fixture and a message generator to generate the wanted input signal.
The source of the wanted input signal, modulated with normal test modulation (see subclause 4.2), shall
be located outside the test environment. The signal level used shall be chosen to a value significantly
above the threshold sensitivity but below the overload characteristics of the receiver (the signal level
should be 60 dB above the threshold sensitivity, if possible). Adequate measures shall be taken to protect
the measuring equipment from the effect of all the radiated fields within the test environment.
Where the receiver incorporates an RF antenna connector, the RF signal source shall be coupled to the
input of the receiver via a shielded transmission line such as a coaxial cable.

Page 13
ETS 300 741: January 1998
Where the receiver does not incorporate a RF connector, the RF signal source shall be presented to the
receiver from another antenna located within the test environment. This antenna shall be coupled to the
RF signal source via an adjustable attenuator.
4.6 Arrangements for test signals at the output of the pocket receiver
From the performance check before and after the test it shall be possible to assess the performance of
the pocket receiver from the presented messages and/or the call received alert signal(s) of the receiver.
During the spot frequency test of the radio frequency immunity test (see subclause 9.2) the call received
alert signal output of the receiver shall be coupled to the outside of the test environment and it shall be
possible to assess the performance of the equipment from the call received alert signal(s) of the receiver.
4.7 Exclusion bands
Exclusion bands are determined frequency bands for which the wide-area paging equipment is excluded
from RF immunity tests.
4.7.1 Exclusion bands for receivers
The exclusion band for receivers is the frequency range determined by the alignment range, as declared
by the manufacturer, extended as follows:
- for receivers operating in the frequency band of 25 MHz to 80 MHz, the lower frequency of the
exclusion band is the lower frequency of the alignment range minus 10 % of the centre frequency of
the alignment range or minus 5 MHz, whichever results in the lowest frequency, and the upper
frequency of the exclusion band is the upper frequency of the alignment range plus 10 % of the
centre frequency of the alignment range or plus 5 MHz whichever results in the higher frequency;
- for receivers operating above 80 MHz, the lower frequency of the exclusion band is the lower
frequency of the alignment range minus 5 % of the centre frequency of the alignment range or
10 MHz, whichever results in the lower frequency, and the upper frequency of the exclusion band is
the upper frequency of the alignment range plus 5 % of the centre frequency of the alignment range
or plus 10 MHz, whichever is greater.
4.7.2 Exclusion band for transmitters
For transmitters operating, or intended to operate, in a channelised frequency band, the exclusion band is
three times the channel separation, centred around the nominal operating frequency.
4.8 Narrow band responses on receivers
No immunity tests shall be carried out on frequencies of identified unwanted narrowband responses
(spurious responses) of the receiver. These narrowband responses (spurious responses) are identified by
the following method.
If during the test the unwanted signal causes a non-acceptable degradation in performance (see
subclause 6.3), it is necessary to establish whether this 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 degradation in performance becomes acceptable again (see subclause 6.3), then the response is
considered to be a narrow band response.

Page 14
ETS 300 741: January 1998
If the degradation in performance is still not acceptable, 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 adjusted two and a half times the bandwidth previously referred to. If the
degradation in performance remains non acceptable (see subclause 6.3), the phenomenon is considered
wide band and therefore an EMC problem and the equipment fails the test.
5 Performance assessment
5.1 General
Each type of equipment shall fulfil the requirements of this ETS on all frequencies over which it is intended
to operate. However, the tests shall be performed on one sample for each intended operating band.
The manufacturer shall at the time of submission of the equipment for test, supply information about
ancillary equipment intended to be used with the wide-area paging equipment.
The manufacturer shall at the time of submission of the equipment for test, supply the following
information which shall be recorded in the test report:
- the user control functions and stored data that are required for normal operation and the method to
be used to assess whether these have been lost after EMC stress;
- an exhaustive list of ports, classified as either AC power, DC power or signal/control including the
maximum allowed length of cable connected thereto;
- the bandwidth of the IF filter immediately preceding the demodulator;
- the operating bands over which the equipment is intended to operate;
- the alignment range of the paging receiver;
- the optional features (versions) of the equipment and the actual version of the equipment that is
(which are) submitted for test.
5.2 Standard paging equipment
If the equipment is wide-area paging equipment of a non-specialized nature or wide-area paging
equipment combined with an ancillary equipment the test modulation, test arrangements, etc. as specified
in clause 4 shall apply.
5.3 Special equipment and stand alone tested ancillary equipment
For wide-area paging equipment of a specialized nature and/or ancillary equipment tested on a stand
alone basis the manufacturer shall define the method of test to determine the acceptable level of
performance or degradation of performance during and/or after the test. Under these circumstances the
manufacturer also shall provide the following information:
- the primary functions of the equipment to be tested during and after EMC stress;
- the intended functions of the wide-area paging equipment which shall be in accordance with the
documentation accompanying the equipment;
- the pass/failure criteria for the equipment;
- the method of observing a degradation of performance of the equipment.
The method of test to determine the performance or the degradation of performance which is carried out
during and/or after the tests, shall be simple, but at the same time give adequate proof that the primary
functions of the equipment are operational.

Page 15
ETS 300 741: January 1998
5.4 Equipment classification
Wide-area paging equipment, or combinations of equipment declared as capable of being powered for
intended use by the main battery of a vehicle shall additionally be considered as a vehicular mobile
equipment.
Wide-area paging equipment or combinations of equipment declared as being capable of being powered
for intended use by AC mains shall additionally be considered as base station equipment.
5.5 Conformance of ancillary equipment
At the manufacturer's discretion an ancillary equipment may be:
- assessed separately from a receiver or transmitter against all the applicable immunity and emission
clauses of this ETS;

8 Test methods and limits for emission tests
8.1 Test configuration
This subclause defines the requirements for test configurations for tests in the following subclauses and
are as follows:
- measurements 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, e.g. by moving the cables of
the equipment;
- 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 representative 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 operational conditions and to ensure that all the differe
