1 Scope
This European Telecommunication Standard (ETS) covers the assessment of radio communication and
ancillary equipment in respect of Electro-Magnetic Compatibility (EMC). Technical specifications related to
the antenna port and emissions from the enclosure port of radio equipment are found in the related
product standards I-ETS 300 131 (1992) [3], and I-ETS 300 131 (1994) second edition [4].
This ETS specifies the minimum performance and the methods of measurements of EMC on second
generation Cordless Telephone (CT2) apparatus and ancillary equipment.
This ETS specifies the applicable EMC tests, the limits, and the performance criteria for digital radio
equipment as described in I-ETS 300 131 [3] or [4], operating in the frequency range 864,1 to 868,1 MHz,
and for 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 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 and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
ancillary equipment: Equipment (apparatus), used in connection with a receiver or transceiver is
considered as an ancillary equipment (apparatus) if:
- the equipment is intended for use in conjunction with a receiver, 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 or transceiver; and
- the receiver 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).
base station equipment: Used to describe CT2 equipment including CFPs (cordless fixed parts) and/or
CPPs (cordless portable parts) as defined in I-ETS 300 131 [3] [4] which are powered via an ac power
input port or a dc power input port.
CT2 equipment: Apparatus which includes one or more transceivers and/or receivers and/or parts
thereof which conform to the requirements of clause 4 of I-ETS 300 131 [3] [4].

host equipment: Any equipment which has a complete user functionality when not connected to the CT2
radio equipment, and to which the CT2 radio equipment provides additional functionality, and to which
connection is necessary for the CT2 radio equipment to offer functionality.
integral antenna: An antenna designed to be connected to the equipment without the use of an external
connector and considered to be part of the equipment. An integral antenna may be fitted internally or
externally to the equipment.
manufacturer: The legal entity responsible for placing the product on the market.
mobile equipment: Used to describe all CT2 equipment powered by a vehicular power supply.
port: A particular interface of the specified equipment (apparatus) with the external electro-magnetic
environment.
portable equipment: Used to describe all CT2 equipment powered by an internal battery.
NOTE: More than one of the equipment classifications may apply to certain equipment, as
described in subclause 5.2, dependent upon the manufacturer's declaration of normal
intended use.
3.2 Abbreviations

FP Cordless Fixed Part
CT2 second generation Cordless Telephone
CPP Cordless Portable Part
EMC Electro-Magnetic Compatibility
ESD Electro-Static Discharge
EUT Equipment Under Test
LISN Line Impedance Stabilisation Network

4 General test conditions
4.1 Test conditions
The equipment shall be tested under normal test conditions contained in the relevant product and basic
standards or in the information accompanying the equipment, which are within the manufacturer's
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 the Equipment Under Test (EUT) is provided with a detachable antenna, the EUT shall be
tested with the antenna fitted in a manner typical of normal intended use.
For CT2 equipment parts for which connection to a host equipment is necessary to offer functionality the
test configuration shall be as defined in subclause 5.4.
4.2 Arrangements for test signals at the input of the transceiver
4.2.1 Speech equipment
Audio input signals may be connected to the EUT either by a non-metallic acoustic tube or, if provided, by
electrical connections. The CT2 equipment shall not be modified to provide any electrical connection ports

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

SIST ETS 300 446 E1:2003
Page 10
ETS 300 446: June 1996
for the purposes of this test. Suitable test arrangements for the acoustic tube are described in
I-ETS 300 176 [5].
4.3 Normal test modulation
The wanted input signal shall have the maximum peak frequency deviation which is specified in
I-ETS 300 131 [3] and [4], subclause 4.5.2.
4.4 Connection of test signals for transceivers
4.4.1 Radio Frequency (RF) connection
Where the equipment incorporates an external antenna connector, the wanted signal to establish
communications shall be delivered to that connector by a coaxial cable.
The source of the wanted input signal shall be located outside of the test environment.
Where the equipment does not incorporate an external RF connector (integral antenna equipment), the
wanted signal to establish communications shall be delivered from the equipment to an antenna located
within the test environment.
4.5 Connection of test signals for receiver-only equipment
4.5.1 RF connection
Where the equipment incorporates an external antenna connector, the wanted signal to establish
communications shall be presented to that connector by a coaxial cable.
The source of the wanted input signal shall be located outside of the test environment.
Where the equipment does not incorporate an external RF connector (integral antenna equipment), the
wanted signal, to establish communications, shall be presented to the equipment from an antenna located
within the test environment. Adequate measures shall be taken to protect the measuring equipment from
the effect of all the radiated fields within the test environment.
4.6 Receiver test signal level
For tests on receivers and the receiver parts of transceivers the level of the wanted input signal shall be
adjusted to approximately 40 dB above the radio receiver sensitivity limit as defined in I-ETS 300 131 [3]
and [4].
The source of the wanted input signal shall be located outside of the test environment.
4.7 Narrow band responses on receivers or receivers which are part of transceivers
No immunity tests shall be carried out on frequencies of identified narrow band responses (i.e. spurious
responses) of the receiver parts of the CT2 equipment.
A spurious response is defined as a failure of the communications state between a CFP or CPP and its
corresponding CPP or CFP due to the introduction of interfering radio signals, at any frequency within a
continuous frequency band of width 1 MHz or less at a lower field strength than given as the limiting value
in I-ETS 300 131 [3] and [4], subclause 4.6.3.1 at that frequency equal to the centre frequency of this
band.
The procedure by which a narrow band response is distinguished from a wide band response is as
follows:
- if during testing the communications link is dropped, or there is an increase above the permitted
level in the measured value of speech output signal level, the frequency of the unwanted signal
shall be recorded and then increased by 1 MHz and the test repeated. Similarly, the frequency of
the unwanted signal shall be set to the frequency recorded in the previous test, and then decreased
by 1 MHz and the test repeated;

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

SIST ETS 300 446 E1:2003
Page 11
ETS 300 446: June 1996
- if the communications link is maintained and the speech output signal of the EUT as measured is
within the permitted limit at the two test frequencies described in the previous paragraph, then the
response observed at the recorded frequency of the unwanted signal shall be considered a narrow
band response and shall not be used in determining the EMC compliance of the EUT;
- if the communications link is dropped or the speech output signal level of the EUT as measured is
outside the permitted limits at the two test frequencies, then the test shall be repeated using
frequency offsets of plus and minus 1,5 MHz. If at one or both of this second set of test frequencies
the communications link is dropped or the speech output signal level as measured is still outside
the permitted limits, then the response is considered to be a wide band phenomena and the EUT
fails the test.
4.8 Exclusion bands
Frequencies on which the EUT is intended to operate are excluded from immunity tests with either
conducted or radiated unwanted RF signals. For the purposes of this ETS these frequencies are referred
to as "exclusion bands".
4.8.1 Exclusion band for CT2 receivers and CT2 receiver parts of transceivers
The exclusion band for a receiver or a receiver part of a transceiver shall extend from 820,9 MHz to
911,5 MHz.
4.8.2 Exclusion band for CT2 transmitter parts of transceivers
The exclusion band for the transmitter part of a transceiver shall extend from 820,9 MHz to 911,5 MHz.
NOTE: The product operates on a single frequency in a time-division multiplex mode. For this
reason, it is not practical to configure test equipment to use an exclusion band for the
transmitter that is narrower than that used for the receiver. As a result, the specified
exclusion band for transmitters has been set equal to the exclusion band for receivers.
5 Performance assessment
5.1 General
The manufacturer shall at the time of submission of the equipment for test, declare the following
information which shall be recorded in the test report:
- in the case of receive-only equipment, the primary functions of the radio 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 and/or host equipment to be used with the radio equipment 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 edition of the performance standard I-ETS 300 131 [3] or [4] which the EUT is intended to meet;
- the volume setting required to provide nominal operation of the product as defined in
I-ETS 300 131 [3] or [4].
