1 Scope
This European Telecommunication Standard (ETS) covers the assessment of Double Side Band (DSB)
and/or Single Side Band (SSB) modulated Citizens' Band (CB) radio and ancillary equipment in respect of
electromagnetic compatibility (EMC).
This ETS specifies the applicable EMC tests, the test methods, the limits and the minimum performance
criteria for DSB and/or SSB modulated CB Radio equipment (speech and/or non-speech) operating in the
frequency range 26 - 28 MHz, and the associated ancillary equipment.
The environmental classification used in this ETS refers to the environment classification used in the
Generic Standards EN 50081-1 [4], EN 50082-1 [5], except for the vehicular environment class which
refers to the ISO 7637 standard [14].
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 do not cover extreme
cases which may occur in any location but have 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 with the requirements of this ETS does not signify compliance to any
requirements related to the use of the equipment (i.e. licensing requirements).
Compliance with this ETS does not signify compliance to any safety requirements. However, it is the
responsibility of the assessor of the equipment that any observations regarding apparatus 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, abbreviations and symbols
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
ancillary equipment: Equipment (apparatus), used in connection with a receiver, transmitter or
transceiver is considered as an ancillary equipment (apparatus) if:
- the equipment is intended for use in conjunction with a receiver, transmitter or transceiver to
provide additional operational and/or control features to the radio equipment (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
receiver, transmitter or transceiver; and
- the receiver, transmitter or transceiver to which it is connected, is capable of providing some
intended operation such as transmitting and/or receiving without the ancillary equipment. (i.e. it is
not a sub unit of the main equipment essential to the main equipment basic functions).
enclosure port: The physical boundary of the apparatus onto which an electromagnetic field may radiate
or impinge.
integral antenna equipment: CB equipment without an accessible external transmission line interface.
Integral antenna CB equipment in the context of this ETS should be understood to be low power handhold

4 General test conditions
4.1 Test conditions
This subclause defines the requirements for the general test configuration and are as follows:
- the equipment shall be tested under conditions which are within the manufacturers declared range
of humidity, temperature and supply voltage;
- the test configuration shall be as close to normal intended use as possible;
- integral antenna CB equipment shall be tested in a manner typical of normal intended use;
- 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;
- 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 impedance of the ancillary
equipment. Radio Frequency (RF) input/output ports shall be correctly terminated;

---------------------- Page: 11 ----------------------

SIST ETS 300 680-2:1998
Page 10
ETS 300 680-2: March 1997
- 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;
- ports which are not connected to cables during normal intended 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 Equipment Under Test (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 tests shall be carried out at a point within the specified normal operating environmental range at
the rated supply voltage for the equipment;
- the test conditions, test configuration and mode of operation shall be recorded in the test report.
4.1.1 Emission tests
This subclause defines the requirements for the emissions test configuration and are as follows:
- the measurement shall be made in the operation 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.
The CB radio equipment shall be operated on one channel frequency, which is close to the middle of the
switching range declared by the manufacturer.
4.1.2 Immunity tests
This subclause defines the requirements for the immunity test configuration and are as follows:
- the measurement shall be made in the mode of operation as required in subclause 4.1.2.1;
- for the immunity tests of ancillary equipment without a separate pass/fail criteria, the receiver,
transmitter or transceiver coupled to the ancillary equipment shall be used to judge whether the
ancillary equipment passes or fails;
- immunity tests on CB radio equipment shall be carried out on one channel which is close to the
middle of the switching range declared by the manufacturer.
4.1.2.1 Mode of operation
For the immunity tests of transmitters, the transmitter shall be operated at its maximum RF output peak
envelope power, or at a level not less than 6 dB below that power level in the event of declared thermal
limitations. The transmitter is modulated with normal test modulation (see subclauses 4.1.2.2 and 4.1.2.3).
A communication link shall be established (see subclause 4.1.2.4) at the start of the test.
For the immunity tests of receivers, the wanted input signal, coupled to the receiver, shall be modulated
with normal test modulation (see subclauses 4.1.2.2 and 4.1.2.5). A communication link shall be
established (see subclause 4.1.2.6) at the start of the test.
4.1.2.2 Normal test modulation
For analogue speech applications:
- the receiver wanted input signal shall be set to the nominal frequency of the receiver modulated
with a sinusoidal audio frequency of 1 000 Hz. In case of DSB (AM) a modulation depth of at least
60 % shall be used for the wanted test signal. For SSB receivers the wanted signal shall be in the
receiver passband at a frequency giving a 1 kHz audio output;

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

SIST ETS 300 680-2:1998
Page 11
ETS 300 680-2: March 1997
- in case of DSB (AM), the transmitter of the EUT shall be modulated with a sinusoidal audio
frequency signal of 1 000 Hz. The level of this audio signal shall be set to obtain at least 60 % AM
modulation depth of the RF output signal;
- in case of SSB, the transmitter of the EUT shall be modulated with a sinusoidal audio frequency
signal of 1 000 Hz, the level shall be set to obtain 60 % of the maximum peak envelope RF output
power. The level of this audio signal shall be increased by 3 dB and this signal shall be used as
normal test modulation signal.
For non-speech applications:
- the receiver wanted input signal shall be set to the nominal frequency of the receiver modulated
with a test signal specified by the manufacturer which represents normal operation;
- the transmitter shall be modulated with a test signal which represents normal operation as specified
by the manufacturer.
The test signal generator (modulation) shall be able to produce a continuous stream of data or a repetitive
message.
The test signal receiver (demodulator) shall be able to produce a readout of Bit Error Ratio (BER) of a
continuous data stream or a repetitive readout of message acceptance.
4.1.2.3 Arrangements for test signals at the input of the transmitter
The transmitter should be modulated with normal test modulation.
4.1.2.4 Arrangements for test signals at the output of the transmitter
For integral antenna CB equipment, the wanted signal, to establish a communication link, shall be
delivered from the equipment to an antenna located within the test environment. The measuring
equipment for the wanted signal shall be located outside of the test environment. Adequate measures
shall be taken to avoid the effect of the unwanted signal on the measuring equipment.
For equipment with an external coaxial antenna connector (non-integral antenna CB-equipment), the
wanted signal to establish a communication link shall be delivered from the antenna connector by a
coaxial cable. The measuring equipment for the wanted signal shall be located outside of the test
environment. Adequate measures shall be taken to avoid any effect of the unwanted signal on the
measuring equipment.
4.1.2.5 Arrangements for test signals at the input of the receiver
For integral antenna CB equipment, the wanted input signal, to establish a communication link, shall be
presented to the equipment from an antenna located within the test environment. It shall be approximately
40 dB above the minimum level necessary to achieve normal operation performance, as declared by the
manufacturer, measured while the power amplifiers generating the EMC disturbance are switched on but
without excitation. This level of the wanted input signal is expected to represent normal operation signal
level and is sufficient to prevent the broad band noise from the power amplifiers from influencing the
measurement. The source of the wanted input signal shall be located outside of the test environment.
For equipment with an external coaxial antenna connector (non-integral antenna CB equipment), the
wanted input signal to establish a communication link shall be presented to the antenna connector by a
coaxial cable. The source of the wanted input signal shall be located outside of the test environment and
shall be at a nominal value of 40 dBμV emf.
4.1.2.6 Arrangements for test signals at the output of the receiver
For speech equipment the audio frequency output of the equipment shall be coupled via a suitable
coupling device in order to demonstrate that the communication link is maintained. Precautions shall be
taken to ensure that any effect on the test is minimized.
