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 Digital
Enhanced Cordless Telecommunications (DECT) radio and ancillary equipment.
This ETS specifies the applicable EMC tests, the limits, and the performance criteria for digital radio
equipment as described in ETS 300 175-2 [4] and I-ETS 300 176 [5], operating in the frequency range
1 880 to 1 900 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] and EN 50082-1 [2], except the vehicular environment class which
refers to ISO 7637 [6], [7].
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.

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.
---------------------- Page: 11 ----------------------
SIST ETS 300 329:1998
Page 10
ETS 300 329: June 1997
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 DECT 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 Loop back data
The normal test modulation shall be transmitted by the test system and looped back in the radio
equipment, as described in ETS 300 175-3 [8] and I-ETS 300 176 [5].
4.2.2 Speech equipment
Audio input signals may be connected to the EUT either by a non-metallic acoustic tube or, if provided,
electrical connections. The DECT equipment shall not be modified to provide any electrical connection
ports 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
For all types of DECT equipment the wanted input signal shall be a Radio Frequency (RF) carrier set to
the nominal centre frequency of one of the DECT RF channels, using gaussian shaped frequency-shift
keying (BT = 0,5) and modulated with a 1 152 kbit/s bit sequence.
The encoding of the bit sequence shall conform to the encoding specified in ETS 300 175-2 [4] and
ETS 300 175-3 [8].
The parts of the data sequence that shall transmit a bit sequence conforming to the D-M2 pattern as
specified in ITU-T Recommendation 0.153 [9] are those which are looped back according to the loop back
test message described in ETS 300 175-3 [8].
The burst timings of this carrier shall conform to the limits specified in ETS 300 175-2 [4].
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. Adequate measures shall be
taken to minimize the effect of unwanted currents on the external conductor of the coaxial cable at the
point of entry to the equipment.
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 i.e. integral antenna equipment, the
wanted signal to establish communications shall be delivered from the equipment to 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.
4.5 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. Adequate measures shall be
taken to minimize the effect of unwanted currents on the external conductor of the coaxial cable at the
point of entry to the equipment.
---------------------- Page: 12 ----------------------
SIST ETS 300 329:1998
Page 11
ETS 300 329: June 1997
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 i.e. 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 ETS 300 175-2 [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 DECT equipment.
The procedure by which a narrow band response is distinguished from a wide band response is as
follows:
- if during testing an increase in the bit error rate of the looped back data from the EUT is observed,
or there is an increase in the measured value of speech output signal level, the frequency of the
unwanted signal shall be recorded and then increased by 2 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 2 MHz and the test repeated;
- if the bit error rate and speech output signal of the EUT as measured are within the permitted limits
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 bit error rate or 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 2,5 MHz. If at this second set of test frequencies the bit error rate or 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.
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;
