1 Scope
This European Telecommunication Standard (ETS) covers the assessment of radio communication and
ancillary equipment in respect of Electromagnetic Compatibility (EMC).
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, 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) 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 operate in the frequency band 864,1 MHz to 868,1 MHz.

Page 11
ETS 300 446: March 1997
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

3.2 Abbreviations
For the purposes of this ETS, the following abbreviations apply:
CT2 second generation Cordless Telephone
CTA Cordless Telephone Apparatus
CFP Cordless Fixed Part
CPP Cordless Portable Part
EMC ElectroMagnetic Compatibility
EUT Equipment Under Test
SPL Sound Pressure Level
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 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.

SIST ETS 300 446:1998
Page 12
ETS 300 446: March 1997
4.3 Normal test modulation
The wanted input signal shall have the maximum peak frequency deviation which shall lie between
14,4 kHz and 25,2 kHz.
4.4 Connection of test signals for transceivers
4.4.1 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 annex B, taken from 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: 14 ----------------------

SIST ETS 300 446:1998
Page 13
ETS 300 446: March 1997
- 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
