3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 301 489-1 [1] and the following apply:
ancillary equipment: electrical or electronic equipment, that is intended to be used with a receiver or transmitter
NOTE 1: It is considered as an ancillary equipment if:
 the equipment is intended for use with a receiver or transmitter to provide additional operational
and/or control features to the radio equipment, (e.g. to extend control to another position or
location); and
 the ancillary equipment cannot be used without being connected to radio equipment to provide user
functions independently of a receiver or transmitter; and
 the receiver or transmitter, 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).
NOTE 2: An example of ancillary equipment would be a docking station for radio equipment whose interface is
dedicated to a particular product or range of products.
base station: radio equipment intended for operation at a fixed location which is not defined as portable equipment
critical stored data: data that is essential for an EUT to perform a primary function in accordance with that EUT's
specification
integral antenna: antenna designed for permanent connection to the equipment and considered part of the enclosure
port
NOTE: An integral antenna may be fitted internally or externally.
mobile equipment: receiver, transmitter or transmitter/receiver (transceiver) intended for installation and use in a
vehicle, and powered by a vehicle battery
Pmin: minimum power required to establish a communications link
ETSI
9 ETSI EN 301 489-13 V2.1.1 (2025-10)
portable equipment: radio equipment intended for portable use and powered by integral batteries or batteries
NOTE: Devices will typically be handheld.

For the purposes of the present document, the test conditions of ETSI EN 301 489-1 [1], clause 4, shall apply with the
following additions. Further product related test conditions for CB radio and ancillary equipment are specified in
clauses 4.2 to 4.4.
The CB radio equipment shall be operated on the channel closest to the middle of the switching range for each
modulation scheme supported by the EUT.
4.2 Arrangements for test signals
4.2.1 Arrangements for test signals at the input of transmitters
The transmitter shall be exercised with a signal, representing the EUT's intended use. Where this signal is provided by
an external source, the source may be located outside the test environment.
ETSI
10 ETSI EN 301 489-13 V2.1.1 (2025-10)
4.2.2 Arrangements for test signals at the output of transmitters
The Monitoring Equipment (ME) for the wanted RF output signal from the transmitter with an antenna connector shall
be located outside the test environment and shall be connected to the transmitter via a shielded transmission line, such
as a coaxial cable.
For transmitters with an integral antenna, the wanted RF output signal to establish a communication link shall be
delivered from the transmitter to an antenna located within the test environment. This antenna shall be connected to the
ME via a shielded transmission line, such as a coaxial cable, so as to not influence the measurement results.
The level of the wanted RF output signal in transmit mode of operation shall be set to the maximum rated RF power for
the EUT or at a level not less than 6 dB below that power level in the event of thermal limitations.
4.2.3 Arrangements for test signals at the input of receivers
For receivers with an antenna connector, the wanted RF input signal to establish a communication link shall be located
outside of the test environment and connected to the antenna connector of the EUT by a shielded transmission line, such
as a coaxial cable.
For receivers with an integral antenna, the wanted RF input signal to establish a communication link shall be presented
to the EUT from an antenna located within the test environment. This antenna shall be connected to the external RF
signal source by a shielded transmission line, such as a coaxial cable.
For radiated immunity tests,

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 301 489-1 [1] and the following apply:
ancillary equipment: electrical or electronic equipment, that is intended to be used with a receiver or transmitter
NOTE 1: It is considered as an ancillary equipment if:
 the equipment is intended for use with a receiver or transmitter to provide additional operational
and/or control features to the radio equipment, (e.g. to extend control to another position or
location); and
 the ancillary equipment cannot be used without being connected to radio equipment to provide user
functions independently of a receiver or transmitter; and
 the receiver or transmitter, 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).
NOTE 2: An example of ancillary equipment would be a docking station for radio equipment whose interface is
dedicated to a particular product or range of products.
base station: radio equipment intended for operation at a fixed location which is not defined as portable equipment
critical stored data: data that is essential for an EUT to perform a primary function in accordance with that EUT's
specification
integral antenna: antenna designed for permanent connection to the equipment and considered part of the enclosure
port
NOTE: An integral antenna may be fitted internally or externally.
mobile equipment: receiver, transmitter or transmitter/receiver (transceiver) intended for installation and use in a
vehicle, and powered by a vehicle battery
Pmin: minimum power required to establish a communications link
ETSI
9 ETSI EN 301 489-13 V2.1.1 (2025-10)
portable equipment: radio equipment intended for portable use and powered by integral batteries or batteries
NOTE: Devices will typically be handheld.
switching range: maximum frequency range over which the equipment can be used without reprogramming or
rearrangement
vehicle use: radio equipment intended for installation and use in a vehicle, and powered by a vehicle battery

4 Test conditions
4.1 General
For the purposes of the present document, the test conditions of ETSI EN 301 489-1 [1], clause 4, shall apply with the
following additions. Further product related test conditions for CB radio and ancillary equipment are specified in
clauses 4.2 to 4.4.
The CB radio equipment shall be operated on the channel closest to the middle of the switching range for each
modulation scheme supported by the EUT.
4.2 Arrangements for test signals
4.2.1 Arrangements for test signals at the input of transmitters
The transmitter shall be exercised with a signal, representing the EUT's intended use. Where this signal is provided by
an external source, the source may be located outside the test environment.
ETSI
10 ETSI EN 301 489-13 V2.1.1 (2025-10)
4.2.2 Arrangements for test signals at the output of transmitters
The Monitoring Equipment (ME) for the wanted RF output signal from the transmitter with an antenna connector shall
be located outside the test environment and shall be connected to the transmitter via a shielded transmission line, such
as a coaxial cable.
For transmitters with an integral antenna, the wanted RF output signal to establish a communication link shall be
delivered from the transmitter to an antenna located within the test environment. This antenna shall be connected to the
ME via a shielded transmission line, such as a coaxial cable, so as to not influence the measurement results.
The level of the wanted RF output signal in transmit mode of operation shall be set to the maximum rated RF power for
the EUT or at a level not less than 6 dB below that power level in the event of thermal limitations.
4.2.3 Arrangements for test signals at the input of receivers
For receivers with an antenna connector, the wanted RF input signal to establish a communication link shall be located
outside of the test environment and con
