SIST ETS 300 340:1998 is the ETSI European Telecommunication Standard for electromagnetic compatibility (EMC) of European Radio Message System (ERMES) paging receivers and associated ancillary equipment. It specifies the EMC tests, measurement methods, limits and minimum performance criteria used to assess these receivers, and it may be used to show presumption of compliance with the EMC Directive 89/336/EEC.
What does SIST ETS 300 340:1998 specify?
SIST ETS 300 340:1998 covers EMC assessment for ERMES paging receivers and ancillary equipment, with a focus on both emissions and immunity. The document is organized into clauses on scope, normative references, definitions, general test conditions, performance assessment, performance criteria, applicability overview tables, emission tests and immunity tests.
Tables 1 and 2 show which tests apply to base station, mobile, portable and ancillary equipment. This matters in practice because the test plan depends on the product type and intended use, especially whether the equipment is fixed, vehicular, portable or only ancillary.
What are the key requirements of SIST ETS 300 340:1998?
Test conditions and setup
SIST ETS 300 340:1998 requires testing under the declared humidity, temperature and supply-voltage range, with the test configuration as close as possible to normal intended use. The equipment report has to record the test conditions and the configuration used.
If the paging receiver has a detachable antenna, it is tested with the antenna fitted in the normal way. For immunity tests, the wanted signal is modulated with normal test modulation, and the test arrangement has to allow the receiver to be checked for stored messages and call reception.
Performance assessment and pass/fail criteria
SIST ETS 300 340:1998 requires the manufacturer to provide, at submission, the intended functions, the ancillary equipment to be used, the list of ports, the user controls and stored data to be checked, and the bandwidth of the IF filter before the demodulator. That information is needed so the laboratory can judge whether the main paging functions still work after EMC stress.
Where the receiver can establish a communications link, performance is judged by the link and by the call-received alert signal. Where no link is possible, or where ancillary equipment is tested on its own, the manufacturer has to define a practical pass/fail method. The standard uses two main performance criteria:
- CR for continuous phenomena
- TR for transient phenomena
In practice, that means the test report has to show whether the receiver kept its memory, avoided false calling and still operated as intended after each exposure.
Emission testing
SIST ETS 300 340:1998 covers enclosure emissions for ancillary equipment, conducted emissions on dc power ports, and conducted emissions on ac mains ports. The enclosure test applies to ancillary equipment not built into the receiver, and the conducted tests apply according to the equipment type and cabling.
The emission methods refer to EN 55022 and CISPR 16-1. Class B limits apply for the relevant enclosure and conducted tests. This matters because manufacturers and test labs need to control radiated and conducted noise from the enclosure and power ports before the product can be placed in service.
Immunity testing
SIST ETS 300 340:1998 defines immunity tests for several disturbance types:
- RF electromagnetic field over 80 MHz to 1 000 MHz
- Electrostatic discharge
- Fast transients on suitable ports
- RF common-mode disturbance from 150 kHz to 80 MHz
- Vehicular transients and surges for mobile and vehicular equipment
- Voltage dips and interruptions on ac mains
- Surges on ac mains
The RF field test uses a 3 V/m level with amplitude modulation, and narrow-band responses are disregarded. Electrostatic discharge, fast transients, conducted RF immunity, and surge-related tests each use performance criteria tied to CR or TR, depending on the disturbance and equipment class.
For vehicular use, the standard refers to ISO 7637 and distinguishes 12 V and 24 V supply cases, including whether the equipment is directly connected to the vehicle battery. For ac-mains-powered equipment, the standard also addresses voltage dips, interruptions and surges, which matters for base station receivers and fixed ancillary equipment installed on mains power.
Ancillary equipment handling
SIST ETS 300 340:1998 allows ancillary equipment to be treated in three ways: declared compliant on its own, declared compliant under another suitable harmonized EMC standard, or tested together with the paging receiver. This is important for system integrators because the compliance route can depend on how the ancillary equipment is marketed and used.
What terms does SIST ETS 300 340:1998 define?
- Ancillary equipment - Equipment used with a paging receiver to add control or operational functions, but not able to work as a stand-alone user device.
- ERMES paging receiver - A receiver that operates in the ERMES paging system.
- Manufacturer - The legal entity responsible for placing the product on the market under Council Directive 89/336/EEC.
- Port - A specific interface between the equipment and the electromagnetic environment.
- Equipment Under Test (EUT) - The item being evaluated in the EMC test.
- CR - Continuous phenomena performance criterion applied to receivers.
- TR - Transient phenomena performance criterion applied to receivers.
Who uses SIST ETS 300 340:1998?
SIST ETS 300 340:1998 is used by manufacturers of ERMES paging receivers and ancillary equipment, EMC test laboratories, and assessors preparing test reports. It is also used by product engineers and quality managers who need to define the test configuration, ports, performance criteria and acceptance checks before testing.
In practice, it supports design verification, compliance testing and documentation for receivers intended for residential, commercial, light industrial and vehicular environments.
Which standards are used with SIST ETS 300 340:1998?
SIST ETS 300 340:1998 is based on, and refers to, several companion standards:
- EN 50081-1 - generic emission standard for residential, commercial and light industry environments
- EN 50082-1 - generic immunity standard for the same environments
- ETS 300 133, Parts 1 to 7 - ERMES paging system standard used for receiver definition and normal test modulation
- EN 55022 - emission limits and methods used for enclosure and conducted emissions
- CISPR 16-1 - measurement receiver and apparatus requirements for conducted emission testing
- ENV 50140 - radiated RF immunity test method
- IEC 801-2 - electrostatic discharge test method
- IEC 801-4 - fast transient/burst test method
- ENV 50141 - conducted RF immunity by current clamp injection
- IEC 1000-4-11 - voltage dips and interruptions
- IEC 1000-4-5 - surge immunity
- ISO 7637 - vehicular electrical disturbance tests for 12 V and 24 V systems
- Council Directive 89/336/EEC - the EMC Directive referenced for presumption of compliance
What does the SIST ETS 300 340:1998 document contain?
The document contains the test framework for EMC evaluation of ERMES paging receivers and ancillary equipment, including applicability tables for emission and immunity. It also sets out general test conditions, how to establish and check a communications link, and how to judge receiver memory, false calling and alert signaling.
The body of the standard gives the test methods and limits for enclosure radiation, conducted emissions on dc and ac ports, and the main immunity tests for radiated RF fields, electrostatic discharge, fast transients, conducted RF, vehicular transients and surges, voltage dips and mains surges. It also explains how to handle narrow-band responses and how to record test results when special operating conditions or battery backup affect the outcome.

Foreword
This European Telecommunication Standard (ETS) has been prepared by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
Other standards cover radio communications equipment not listed in the scope.
This ETS is based upon the Generic Standards EN 50081-1 [1] and EN 50082-1 [2], ETS 300 339 [3], and
other standards where appropriate, to meet the essential requirements of the Council Directive
89/336/EEC [4].
Every ETS prepared by ETSI is a voluntary standard. This ETS contains text which may be used for
regulatory purposes. This text does not make this ETS mandatory in its status as a standard. However,
the ETS can be referenced, wholly or in part, for mandatory application by decisions of regulatory bodies.

1 Scope
This ETS covers the requirements for the assessment of ERMES paging receivers and ancillary
equipment in respect of Electro-Magnetic Compatibility (EMC) and may be used to demonstrate
presumption of compliance with the protection requirements of Council Directive 89/336/EEC [4], Article 4
(EMC Directive).
This ETS specifies the applicable EMC tests, the method of measurements, the limits and the minimum
performance criteria for ERMES paging receivers (as defined in ETS 300 133 [5]) and the associated
ancillary equipment.
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 the ISO 7637 [6].
The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus at
residential, commercial, light industrial and vehicular environments. The levels, however, do not cover
extreme cases which may occur in any location but with a 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 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.

3 Definitions
For the purposes of this ETS the following definitions apply:
ancillary equipment: Equipment (apparatus), used in connection with a paging receiver is considered as
an ancillary equipment (apparatus) if:
- the equipment is intended for use in conjunction with a paging receiver, to provide additional
operational and/or control features to the paging receiver (e.g. to extend control to another position
or location); and
- the equipment cannot be used on a stand alone basis to provide user functions independently of a
paging receiver; and
- the paging receiver to which it is connected, is capable of providing some intended operation such
as receiving without the ancillary equipment (i.e. it is not a sub-unit of the main equipment essential
to the main equipment basic functions).
ERMES paging receiver: A receiver which operates in the ERMES paging system.
manufacturer: The legal entity responsible under the terms of the Council Directive 89/336/EEC [4] for
placing the product on the market.
port: A particular interface of the specified equipment (apparatus) with the electromagnetic environment.
4 General test conditions
4.1 Test conditions
The equipment shall be tested under conditions contained in the relevant product and basic standards or
in the information accompanying the equipment, which are within the manufacturers declared range of
humidity, temperature and supply voltage.
The test conditions shall be recorded in the test report.
The test configuration shall be as close to normal intended use as possible and shall be recorded in the
test report.
Whenever an ERMES paging receiver is provided with a detachable antenna, the EUT shall be tested
with the antenna fitted in a manner typical of normal intended use.
Page 9
ETS 300 340: November 1994
For the immunity tests of receivers, the wanted input signal (when called for), applied to the receiver, shall
be modulated with normal test modulation, see subclauses 4.2 and 4.3. For all the immunity tests
according to this ETS, except for the spot frequency test of the radio frequency immunity test, see
subclause 9.1, a communication link shall be established and the memory shall be loaded with
recognisable messages, see subclause 4.4.
For the spot frequency test of the radio frequency immunity test, see subclause 9.1, a communication link
shall be established and repetitive calls shall be transmitted to the Equipment Under Test (EUT).
4.2 Normal test modulation
The wanted input signal shall be set to the nominal frequency selected for the EUT and modulated with
normal test modulation, coded according to the ERMES standard ETS 300 133-4 [5], enabling to test that
a communication link is established.
4.3 Arrangements for test signals at the input of the receiver
The manufacturer shall at the time of submission supply a test fixture and a message generator to
generate the wanted input signal according to the ERMES standard, to check that the equipment is able
to receive a call and store it in its memory before and after the test.
During the spot frequency test of radio frequency immunity, see subclause 9.1, the wanted signal, to
establish a communication link and to check that the equipment is capable of receiving a call during the
test, shall be presented to the equipment from an antenna located within the test environment. The level
shall be approximately 60 dB above the level where the equipment just starts reacting on some of the calls
transmitted. The signal generator providing the wanted input signal shall be located outside of the test
environment.
4.4 Arrangements for test signals at the output of the receiver
From the performance check before and after the test it shall be possible to assess the performance of
the equipment from the presented messages and/or from the call received alert signals of the equipment.
During the spot frequency test of radio frequency immunity, see subclause 9.1, the call received alert
signal output of the equipment shall be coupled to the outside of the test environment via non-metallic
means and it shall be possible to assess the performance of the equipment from this signal.
Adequate measures shall be taken to protect the measuring equipment from the effect of all
interferences, e.g. radiated fields and conducted interferences.
4.5 Narrow band responses of ERMES receivers
Responses on ERMES 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 creates a degradation of the call received alert signal acceptance
ratio below 4:5 (four out of five), it is necessary to establish whether the distortion is due to a narrow band
response or to a wide band phenomena. 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 shall be repeated with the frequency of the unwanted signal decreased by the
same amount.
If the degradation disappears, then the response is considered as a narrow band response.
If the degradation 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 adjusted to two and one half times the bandwidth previously referred to. If the
degradation still does not disappear, the phenomena is considered wide band and therefore an EMC
problem and the equipment fails the test.
Narrow band responses are disregarded.

5 Performance assessment
5.1 General
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 primary functions of the ERMES paging equipment to be tested during and after the EMC
testing;
- the intended functions of the EUT which shall be in accordance with the documentation
accompanying the equipment;
- the ancillary equipment to be combined with the paging receiver for testing;
- the ancillary equipment submitted for test on a stand alone basis, not combined with the paging
receiver for testing;
- 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 power or signal/control. Power ports shall further be
classified as ac or dc power;
- the bandwidth of the IF filter immediately preceding the demodulator.
5.2 Equipment which can provide a communications link
If a function of the paging receiver, or combination of a paging receiver and ancillary equipment, permits
the establishment of a communications link, the test modulation, test arrangement etc. as required in
clause 4 apply.
The performance during the spot frequency test of the radio frequency immunity test, see subclause 9.2,
shall be established by assessment of the call received alert signal.
5.3 Equipment which does not provide a communications link
If a function of the paging receiver does not permit a communications link to be established or in the case
of ancillary equipment tested on a stand alone basis, see clause 6, 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. The manufacturer shall provide the following:
- the pass/fail criteria for the EUT;
- the method of observing a degradation of performance of the equipment.
The assessment of the degradation of performance which shall be carried out during and/or at the
conclusion of the tests, shall be simple, but at the same time give adequate proof that the primary
functions of the equipment are operational.
5.4 Equipment classification
ERMES 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.
ERMES paging equipment or combinations of equipment declared as capable of being powered for
intended use by ac mains shall additionally be considered as a base station receiver.

ETS 300 340: November 1994
5.5 Ancillary equipment
At the manufacturers discretion an ancillary equipment may be:
- declared compliant separately from the paging receiver to all the applicable immunity and emission
clauses of this ETS;
- declared compliant to another appropriate harmonized EMC standard;
- tested with it connected to the paging receiver in which case compliance shall be demonstrated to
the appropriate clauses of this ETS.
In each case, compliance enables the ancillary equipment to be used with different receivers, transmitters,
or transceivers.
6 Performance criteria
The equipment shall meet the minimum performance criteria as specified in subclauses 6.1 and 6.2.
For all the immunity tests according to this ETS, except the spot frequency test of radio frequency
immunity, see subclause 9.2:
- the establishment of the communication link and loading of the memory with recognisable
messages at the start of the test;
- the maintenance of the memory and no false calling during the test;
- the assessment of the memory (messages);
- the ability to receive and load the memory at the conclusion of the test;
are used as the performance criteria to ensure that the primary functions of the ERMES paging receiver
are evaluated.
For the spot frequency test of the radio frequency immunity test, see subclause 9.2:
- the establishment of the communication link;
- the call received alert signal and no false calling during the test;
are used as the performance criteria to ensure that the primary functions of the ERMES paging receiver
are evaluated.
If an equipment is of a specialised nature, such that the performance criteria described in subclauses 6.1
and 6.2 are not appropriate, then the manufacturer shall declare, for inclusion in the test report, his own
specification for an acceptable level of perfo
