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].

Page 9
ETS 300 446: June 1996
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.

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 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 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].
Page 12
ETS 300 446: June 1996
5.2 Equipment classification
Portable equipment or combinations of equipment declared as capable of being powered for intended use
by the battery in the vehicle shall additionally be considered as vehicular mobile equipment.
Portable or mobile equipment or combinations of equipment declared as capable of being powered for
intended use by ac mains shall additionally be considered as base station equipment.
5.3 Ancillary equipment
At the manufacturer's discretion an ancillary equipment may be:
- declared compliant separately from a receiver or transceiver to all the applicable immunity and
emission clauses of this ETS;
- declared compliant to another appropriate harmonised EMC standard;
- tested with it connected to a receiver or transceiver, in which case compliance shall be
demonstrated to the appropriate clauses of this ETS.
In each case, compliance enables the ancillary equipment to be used with different receivers, transmitters,
or transceivers.
5.4 Assessment of host connected equipment and plug-in cards
For CT2 equipment parts for which connection to or integration with a host equipment is necessary in
order to offer functionality two alternative approaches are permitted. The manufacturer shall declare which
alternative shall be used.
5.4.1 Alternative A: composite equipment
A combination of CT2 radio equipment part and a specific type of host equipment may be used for
assessment according to this ETS.
Where more than one such combination is intended, each combination shall be tested separately.
Where a specific combination of host equipment and a CT2 radio equipment part is tested as a composite
system for compliance, repeat testing shall not be required for:
- those other combinations of hosts and CT2 radio equipment parts which are based on substantially
similar host models in the circumstance that the variations in mechanical and electrical properties
between such host models are unlikely to significantly influence the intrinsic immunity and unwanted
emissions of the CT2 radio equipment part;
- the CT2 radio equipment part which cannot be used without mechanical, electrical, or software
modification in variations of host equipment different from those represented by the units for which
compliance to this ETS has been demonstrated.
5.4.2 Alternative B: use of a test jig and three hosts
Where the CT2 radio equipment part is intended for use with a variety of host equipment, the
manufacturer shall supply a suitable test jig to enable compliance with this ETS to be assessed.
The test jig shall be designed such that alteration of the CT2 radio equipment part's intrinsic immunity and
unwanted emissions is minimised.
Where connection between the CT2 radio equipment part and the host equipment control and/or power
ports is by cables, optical fibres, or other similar means, this connection to the host shall be considered as
a suitable test jig.
Page 13
ETS 300 446: June 1996
The test jig shall allow the CT2 radio equipment part to be powered and stimulated in a way representative
of the way in which it would be powered and stimulated when connected to or inserted into the host
equipment.
In addition to tests using the test jig the CT2 radio equipment part shall be tested when connected to or
inserted into three different host equipment. These hosts shall be provided by the manufacturer and shall
be selected from the list of compatible hosts published by the manufacturer as part of the user
documentation supplied with the CT2 radio equipment part.
The selection of hosts shall be by agreement with the Notified Body.
Notified bodies shall have the discretion to require the manufacturer to inform them of each deletion from,
or addition to, the list of compatible hosts published in the user documentation.
5.5 Performance assessment test procedure to verify no loss of user control functions or
stored data for CT2 transceivers
The test system shall set up a link in the same manner as the EUT's normal intended use.
Any user defined data fields shall be filled in a way representative of normal intended use.
The test procedure shall verify that the CT2 link is maintained and that there is no loss of user control
functions declared by the manufacturer or loss of the stored user defined data.
5.6 Performance assessment of audio breakthrough
This test is used to measure the effect of continuous EMC phenomena on the analogue speech circuits of
CT2 equipment so fitted.
The test system shall be arranged as shown in figure 1 such that the level of the output signals from the
EUT's speech channels can be recorded on suitable test instruments, though not necessarily in each
channel simultaneously. For a Cordless Portable Part (CPP) with an acoustic transducer this will require
the measurement of Sound Pressure Level (SPL). Pick-up of extraneous back-ground noise by the EUT's
speech transducer (microphone) shall be minimised.
Prior to the test sequence, the reference level of the speech output signal shall be recorded on the test
instrumentation as shown in figure 2. For a CPP with an acoustic speech transducer this shall be
equivalent to 0 dBPa at 1 kHz, applied to the ear reference point in the receive path, and - 5 dBPa at
1 kHz applied to the mouth reference point. For an Cordless Fixed Part (CFP) with analogue speech
circuits and other implementations of CT2 equipment with analogue speech circuits, the reference level
shall be equivalent to these acoustic signals.
At each test frequency the level of the acoustic output signal relative to the reference level shall be
measured.
Where it is necessary to interface to the acoustic transducers of the EUT care shall be taken to ensure
that the disturbance to the electro-magnetic field is minimised. The use of a non-metallic acoustic coupler
as described in I-ETS 300 176 [5] is recommended.
The precise arrangements shall be recorded in the test report.

8 Test methods and limits for emission tests of transceivers and/or receivers
and/or ancillary equipment
8.1 Test configuration
This subclause defines the requirements for test configurations described in the following subclauses.
The requirements are as follows:
- the measurement shall be made in the operational mode producing the largest emission in the
frequency band being investigated consistent with normal applications;
- the equipment shall be configured in a manner which is representative of normal/typical operation,
where practical;
- an attempt shall be made to maximise the detected radiated emission, for example by moving the
cables of the equipment;
- 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;
- for CT2 equipment parts for which connection to a host equipment is necessary to offer
functionality, the manufacturer shall select which of the alternative performance assessment
configurations described in subclause 5.4 shall be used;
- the configuration and mode of operation during measurements shall be precisely noted in the test
report;
- 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 in normal operation are connected, shall be connected to an ancillary equipment or to a
representative piece of cable terminated to simulate the impedance of the ancillary equipment. RF
input/output ports shall be correctly terminated;
- the tests shall be carried out at a point within the specified operating environmental range and at the
rated supply voltage for the equipment.
8.2 Enclosure
