Page 7ETS 300 680-1: March 19971ScopeThis European Telecommunication Standard (ETS) covers the assessment of angle-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 performancecriteria for angle-modulated CB Radio equipment (speech and/or non-speech) operating in the frequencyrange 26-28 MHz, and the associated ancillary equipment.The environmental classification used in this ETS refers to the environment classification used in theGeneric Standards EN 50081-1 [4], EN 50082-1 [5], except for the vehicular environment class whichrefers to ISO 7637 [14], [15].The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus atresidential, commercial, light industrial and vehicular environments. The levels do not cover extremecases 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 producingindividually 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 specialprotection 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 with anyrequirements 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 theresponsibility of the assessor of the equipment that any observations regarding apparatus becomingdangerous or unsafe as a result of the application of the tests of this ETS, is recorded in the test report.2Normative referencesThis ETS incorporates, by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and relate to the publications listedhereafter. For dated references, subsequent amendments to, or revisions of, any of these publicationsapply to this ETS only when incorporated in it by amendment or revision.

Where cables have to be connected to these ports, or interconnectingcables 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 orextension of these cables;-the tests shall be carried out at a point within the specified normal operating environmental range atthe rated supply voltage for the equipment;-the test conditions, test configuration and mode of operation shall be recorded in the test report.4.1.1Emission testsThis 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 thefrequency band being investigated consistent with normal applications;-an attempt shall be made to maximize the detected radiated emission for example by moving thecables of the equipment.The CB radio equipment shall be operated on one channel frequency, which is close to the middle of theswitching range declared by the manufacturer.4.1.2Immunity testsThis 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 theancillary equipment passes or fails;-immunity tests on CB radio equipment shall be carried out on one channel which is close to themiddle of the switching range declared by the manufacturer.4.1.2.1Mode of operationFor the immunity tests of transmitters, the transmitter shall be operated at its maximum RF output power,or at a level not less than 6 dB below that power level in the event of declared thermal limitations. Thetransmitter shall be modulated with normal test modulation (see subclauses 4.1.2.2 and 4.1.2.3). Acommunication 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 modulatedwith normal test modulation (see subclauses 4.1.2.2 and 4.1.2.5). A communication link shall beestablished (see subclause 4.1.2.6) at the start of the test.4.1.2.2Normal test modulationFor analogue speech applications:-the receiver wanted input signal shall be set to the nominal frequency of the receiver and modulatedwith a sinusoidal audio frequency of 1 000 Hz. The wanted test signal shall have an FM deviation ofat least 1,2 kHz;-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 adjusted to obtain at least 1,2 kHz FM peak deviation.SIST ETS 300 680-1:1998

The measuringequipment for the wanted signal shall be located outside of the test environment. Adequate measuresshall 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), thewanted signal to establish a communication link shall be delivered from the antenna connector by acoaxial cable. The measuring equipment for the wanted signal shall be located outside of the testenvironment. Adequate measures shall be taken to avoid any effect of the unwanted signal on themeasuring equipment.4.1.2.5Arrangements for test signals at the input of the receiverFor integral antenna CB equipment, the wanted input signal to establish a communication link, shall bepresented to the equipment from an antenna located within the test environment. The level of the signalshall be approximately 40 dB above the minimum level necessary to achieve normal operationperformance, as declared by the manufacturer, measured while the power amplifiers generating the EMCdisturbance are switched on but without excitation. This level of the wanted input signal is expected torepresent normal operation signal level and is sufficient to avoid the broad band noise from the poweramplifiers from influencing the measurement. The source of the wanted input signal shall be locatedoutside of the test environment.For equipment with an external coaxial antenna connector (non-integral antenna CB equipment), thewanted input signal to establish a communication link shall be presented to the antenna connector by acoaxial cable. The source of the wanted input signal shall be located outside of the test environment andshall be at a nominal value of 40 dBµV emf.4.1.2.6Arrangements for test signals at the output of the receiverFor speech equipment the audio frequency output of the equipment should be coupled via a suitablecoupling device in order to demonstrate that the communication link is maintained.

Precautions shall be taken to ensure thatany effect on the test is minimized.SIST ETS 300 680-1:1998



Page 12ETS 300 680-1: March 19974.1.2.7Receiver and receivers of transceivers exclusion bandThe exclusion band for receivers and receivers of transceivers is the frequency range determined by theswitching range, as declared by the manufacturer, extended as follows:-the lower frequency of the exclusion band is the lower frequency of the switching range, minus 5 %of the centre frequency of the switching range;-the upper frequency of the exclusion band is the upper frequency of the switching range, plus 5 %of the centre frequency of the switching range.4.1.2.8Transmitter exclusion bandThe exclusion band for transmitters extends ± 25 kHz from the nominal operating frequency of thetransmitter.4.1.2.9Narrow band responses on receivers and receivers of transceiversResponses on receivers or receivers of transceivers occurring during the test at discrete frequencieswhich are narrow band responses (spurious responses), are identified by the method specified in thissubclause.If during the test an unwanted signal creates a degradation of the audio or data output, it is necessary toestablish whether the degradation is due to a narrow band response or to a wide band phenomenon.Therefore, the unwanted signal frequency is increased by an amount equal to twice the bandwidth of thereceiver, as declared by the manufacturer. The test is repeated with the frequency of the unwanted signaldecreased by the same amount.If the degradation disappears, then the response is considered as a narrow band response. If thedegradation remains, this may be due to the fact that the offset has made the frequency of the unwantedsignal correspond to the frequency of another narrow band response. Under these circumstances theprocedure is repeated with the increase and decrease of the frequency of the unwanted signal adjustedtwo and one half times the bandwidth previously referred to.If a degradation remains, the phenomena is considered as a wide band phenomena and therefore anEMC problem. If the degradation is in excess of the maximum permissible degradation, the equipmentfails the test.Narrow band responses shall be disregarded.5Performance assessment5.1GeneralAny instance of the EUT becomin

1 Scope
This European Telecommunication Standard (ETS) covers the assessment of angle-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 angle-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 ISO 7637 [14], [15].
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 with any
requirements 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 observations regarding apparatus becoming
dangerous or unsafe as a result of the application of the tests of this ETS, is recorded in the test report.

SIST ETS 300 680-1:1998
Page 10
ETS 300 680-1: 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 power,
or at a level not less than 6 dB below that power level in the event of declared thermal limitations. The
transmitter shall be 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 and modulated
with a sinusoidal audio frequency of 1 000 Hz. The wanted test signal shall have an FM deviation of
at least 1,2 kHz;
- 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 adjusted to obtain at least 1,2 kHz FM peak deviation.

ETS 300 680-1: March 1997
For non speech applications:
- the receiver wanted input signal shall be set to the nominal frequency of the receiver and 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 measure 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. The level of the signal
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 avoid 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 should 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.
For non-speech equipment the output of the receiver 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.
