4.2 Test conditions
4.2.1 Introduction

For the purposes of the present document, the test conditions of ETSI EN 301 489-1 [1], clause 4 shall apply as

appropriate. Further product related test conditions for wireless microphones, similar RF audio link equipment, cordless

audio, in-ear monitoring equipment and ancillary equipment are specified in the present document.

4.2.2 General

For emission and immunity tests the test modulation, test arrangements, etc., as specified in the present document,

clauses 4.2 to 4.6 shall apply.

For the purpose of EMC tests, body worn or hand held transmitters shall be mounted on a non-conductive stand at least

0,8 m from any conducting surface. The EUT and any other equipment required for the performance assessment before,

during, and after the conclusion of the tests, shall be connected in a manner typical of normal intended use.

Whenever the EUT is provided with a detachable antenna, it shall be tested with the antenna fitted in a manner typical

of normal intended use.

For immunity tests, if the equipment is of a category which permits it, a communications link shall be established at the

start of the test and maintained during the test.
The test conditions shall be as follows:

• the transmitter shall be operated at its normal maximum RF output power modulated with a suitable

modulation signal (see clause 4.6.1);

• for stand alone receivers or receivers of transceivers operating in simplex mode, the wanted RF input signal,

coupled to the receiver, shall be modulated with a suitable modulation signal (see clause 4.6.2);

ETSI
---------------------- Page: 8 ----------------------
9 ETSI EN 301 489-9 V2.1.1 (2019-04)

• for duplex transceivers, the wanted RF input signal, coupled to the receiver, shall be modulated with a suitable

modulation signal (see clause 4.6.2). The transmitter shall be operated at its normal maximum output power,

modulated with the test modulation signal, coupled to the transmitter from the output of the receiver (repeater

mode);

• digitally modulated systems shall use a defined interface to convert between analogue and digital domain (and

vice versa).
4.3 Arrangements for test signals
4.3.1 General
The provisions of ETSI EN 301 489-1 [1], clause 4.2 shall apply.
4.3.2 Arrangements for test signals at the input of transmitters

The provisions of ETSI EN 301 489-1 [1], clause 4.2.1 shall apply with the following modifications.

For transmitters designed to operate from an integral or dedicated microphone (see figure 2) it shall be permissible to

use an acoustic coupling device to inject the normal test modulation signal (see figure 3). The acoustic coupling device

may be provided by the manufacturer.

For equipment which can use a variety of audio capsules, the manufacturer shall declare the type of capsule,

e.g. dynamic, electret, or condenser, to be provided with the system. Only one type of capsule shall be tested. All other

capsules shall be deemed as compliant. The transmitter shall be tested at its most sensitive input with the test capsule.

For equipment not designed to use an integral or dedicated microphone, the test signal shall be fed in electrical form to

the most sensitive input socket (see figure 1) using maximum length cables as normally supplied by the manufacturer

with the equipment.

The modulation signal used for the tests shall be a 1 kHz sine wave tone at a level declared by the manufacturer to

obtain 100 % audio modulation.

The manufacturer may provide a suitable companion receiver that can be used to set up a communications link. In this

case a suitable attenuator in the companion receiver input may be necessary, see annex B for further details.

In the case of systems with a digital audio input and outputs this test signal has to be presented via a suitable test fixture

converting the analogue signal to the digital domain and vice-versa. The applicant shall provide details on the interface

and test fixture used for the test.
4.3.3 Arrangements for test signals at the output of transmitters
The provisions of ETSI EN 301 489-1 [1], clause 4.2.2 shall apply.
4.3.4 Arrangements for test signals at the input of receivers

The provisions of ETSI EN 301 489-1 [1], clause 4.2.3 shall apply with the following modifications.

The wanted RF input signal to the receiver should be modulated with a suitable signal corresponding to 100 % audio

modulation (maximum channel loading). If it is not appropriate to provide a modulated RF signal to the receiver, the

test may be performed using an unmodulated wanted RF input signal.

The level and make up of the wanted RF input signal shall be declared by the manufacturer. The level chosen shall be

set to a value 60 dB above the threshold sensitivity of the receiver. Other systems than analogue radio microphones can

define another level more in line with the application. The level used shall be recorded in the test report.

The manufacturer may provide a suitable companion transmitter that can be used to set up a communications link. In

this case a suitable attenuator in the EUT input may be necessary.

The equipment shall comply with all the technical requirements of the present document which are identified as applicable in annex A at all times when operating within the boundary limits of the declared operational environmental profile. 4.2 Test conditions 4.2.1 Introduction For the purposes of the present document, the test conditions of ETSI EN 301 489-1 [1], clause 4 shall apply as appropriate. Further product related test conditions for wireless microphones, similar RF audio link equipment, cordless audio, in-ear monitoring equipment and ancillary equipment are specified in the present document. 4.2.2 General For emission and immunity tests the test modulation, test arrangements, etc., as specified in the present document, clauses 4.2 to 4.6 shall apply. For the purpose of EMC tests, body worn or hand held transmitters shall be mounted on a non-conductive stand at least 0,8 m from any conducting surface. The EUT and any other equipment required for the performance assessment before, during, and after the conclusion of the tests, shall be connected in a manner typical of normal intended use. Whenever the EUT is provided with a detachable antenna, it shall be tested with the antenna fitted in a manner typical of normal intended use. For immunity tests, if the equipment is of a category which permits it, a communications link shall be established at the start of the test and maintained during the test. The test conditions shall be as follows: • the transmitter shall be operated at its normal maximum RF output power modulated with a suitable modulation signal (see clause 4.6.1); • for stand alone receivers or receivers of transceivers operating in simplex mode, the wanted RF input signal, coupled to the receiver, shall be modulated with a suitable modulation signal (see clause 4.6.2); SIST EN 301 489-9 V2.1.1:2019

ETSI ETSI EN 301 489-9 V2.1.1 (2019-04) 9 • for duplex transceivers, the wanted RF input signal, coupled to the receiver, shall be modulated with a suitable modulation signal (see clause 4.6.2). The transmitter shall be operated at its normal maximum output power, modulated with the test modulation signal, coupled to the transmitter from the output of the receiver (repeater mode); • digitally modulated systems shall use a defined interface to convert between analogue and digital domain (and vice versa). 4.3 Arrangements for test signals 4.3.1 General The provisions of ETSI EN 301 489-1 [1], clause 4.2 shall apply. 4.3.2 Arrangements for test signals at the input of transmitters The provisions of ETSI EN 301 489-1 [1], clause 4.2.1 shall apply with the following modifications. For transmitters designed to operate from an integral or dedicated microphone (see figure 2) it shall be permissible to use an acoustic coupling device to inject the normal test modulation signal (see figure 3). The acoustic coupling device may be provided by the manufacturer. For equipment which can use a variety of audio capsules, the manufacturer shall declare the type of capsule, e.g. dynamic, electret, or condenser, to be provided with the system. Only one type of capsule shall be tested. All other capsules shall be deemed as compliant. The transmitter shall be tested at its most sensitive input with the test capsule. For equipment not designed to use an integral or dedicated microphone, the test signal shall be fed in electrical form to the most sensitive input socket (see figure 1) using maximum length cables as normally supplied by the manufacturer with the equipment. The modulation signal used for the tests shall be a 1 kHz sine wave tone at a level declared by the manufacturer to obtain 100 % audio modulation. The manufacturer may provide a suitable companion receiver that can be used to set up a communications link. In this case a suitable attenuator in the companion receiver input may be necessary, see annex B for further details. In the case of systems with a digital audio input and outputs this test signal has to be presented via a suitable test fixture converting the analogue signal to the digital domain and vice-versa. The applicant shall provide details on the interface and test fixture used for the test. 4.3.3 Arrangements for test signals at the output of transmitters The provisions of ETSI EN 301 489-1 [1], clause 4.2.2 shall apply. 4.3.4 Arrangements for test signals at the input of receivers The provisions of ETSI EN 301 489-1 [1], clause 4.2.3 shall apply with the following modifications. The wanted RF input signal to the receiver should be modulated with a suitable signal corresponding to 100 % audio modulation (maximum channel loading). If it is not appropriate to provide a modulated RF signal to the receiver, the test may be performed using an unmodulated wanted RF input signal. The level and make up of the wanted RF input signal shall be declared by the manufacturer. The level chosen shall be set to a value 60 dB above the threshold sensitivity of the receiver. Other systems than analogue radio microphones can define another level more in line with the application. The level used shall be recorded in the test report. The manufacturer may provide a suitable compani

4.2.1 Introduction

For the purposes of the present document, the test conditions of ETSI EN 301 489-1 [1], clause 4 shall apply as

appropriate. Further product related test conditions for wireless microphones, similar RF audio link equipment, cordless

audio, in-ear monitoring equipment and ancillary equipment are specified in the present document.

4.2.2 General

For emission and immunity tests the test modulation, test arrangements, etc., as specified in the present document,

clauses 4.2 to 4.6 shall apply.

For the purpose of EMC tests, body worn or hand held transmitters shall be mounted on a non-conductive stand at least

0,8 m from any conducting surface. The EUT and any other equipment required for the performance assessment before,

during, and after the conclusion of the tests, shall be connected in a manner typical of normal intended use.

Whenever the EUT is provided with a detachable antenna, it shall be tested with the antenna fitted in a manner typical

of normal intended use.

For immunity tests, if the equipment is of a category which permits it, a communications link shall be established at the

start of the test and maintained during the test.
The test conditions shall be as follows:

• the transmitter shall be operated at its normal maximum RF output power modulated with a suitable

modulation signal (see clause 4.6.1);

• for stand alone receivers or receivers of transceivers operating in simplex mode, the wanted RF input signal,

coupled to the receiver, shall be modulated with a suitable modulation signal (see clause 4.6.2);

ETSI
---------------------- Page: 8 ----------------------
9 Final draft ETSI EN 301 489-9 V2.1.1 (2017-03)

• for duplex transceivers, the wanted RF input signal, coupled to the receiver, shall be modulated with a suitable

modulation signal (see clause 4.6.2). The transmitter shall be operated at its normal maximum output power,

modulated with the test modulation signal, coupled to the transmitter from the output of the receiver (repeater

mode);

• digitally modulated systems shall use a defined interface to convert between analogue and digital domain (and

vice versa).
4.3 Arrangements for test signals
4.3.1 General
The provisions of ETSI EN 301 489-1 [1], clause 4.2 shall apply.
4.3.2 Arrangements for test signals at the input of transmitters

The provisions of ETSI EN 301 489-1 [1], clause 4.2.1 shall apply with the following modifications.

For transmitters designed to operate from an integral or dedicated microphone (see figure 2) it shall be permissible to

use an acoustic coupling device to inject the normal test modulation signal (see figure 3). The acoustic coupling device

may be provided by the manufacturer.

For equipment which can use a variety of audio capsules, the manufacturer shall declare the type of capsule,

e.g. dynamic, electret, or condenser, to be provided with the system. Only one type of capsule shall be tested. All other

capsules shall be deemed as compliant. The transmitter shall be tested at its most sensitive input with the test capsule.

For equipment not designed to use an integral or dedicated microphone, the test signal shall be fed in electrical form to

the most sensitive input socket (see figure 1) using maximum length cables as normally supplied by the manufacturer

with the equipment.

The modulation signal used for the tests shall be a 1 kHz sine wave tone at a level declared by the manufacturer to

obtain 100 % audio modulation.

The manufacturer may provide a suitable companion receiver that can be used to set up a communications link. In this

case a suitable attenuator in the companion receiver input may be necessary, see annex B for further details.

In the case of systems with a digital audio input and outputs this test signal has to be presented via a suitable test fixture

converting the analogue signal to the digital domain and vice-versa. The applicant shall provide details on the interface

and test fixture used for the test.
4.3.3 Arrangements for test signals at the output of transmitters
The provisions of ETSI EN 301 489-1 [1], clause 4.2.2 shall apply.
4.3.4 Arrangements for test signals at the input of receivers

The provisions of ETSI EN 301 489-1 [1], clause 4.2.3 shall apply with the following modifications.

The wanted RF input signal to the receiver should be modulated with a suitable signal corresponding to 100 % audio

modulation (maximum channel loading). If it is not appropriate to provide a modulated RF signal to the receiver, the

test may be performed using an unmodulated wanted RF input signal.

The level and make up of the wanted RF input signal shall be declared by the manufacturer. The level chosen shall be

set to a value 60 dB above the threshold sensitivity of the receiver. Other systems than analogue radio microphones can

define another level more in line with the application. The level used shall be recorded in the test report.

The manufacturer may provide a suitable companion transmitter that can be used to set up a communications link. In

this case a suitable attenuator in the EUT input may be necessary.

4 Technical requirements specifications
4.1 Environmental Profile

The technical requirements of the present document apply under the environmental profile for operation of the

equipment, which shall be declared by the manufacturer. The equipment shall comply with all the technical

requirements of the present document at all times when operating within the boundary limits of the declared operational

environmental profile.
4.2 Test conditions
4.2.1 Introduction

For the purposes of the present document, the test conditions of ETSI EN 301 489-1 [1], clause 4 shall apply as

appropriate. Further product related test conditions for wireless microphones, similar RF audio link equipment, cordless

audio, in-ear monitoring equipment and ancillary equipment are specified in the present document.

4.2.2 General

For emission and immunity tests the test modulation, test arrangements, etc., as specified in the present document,

clauses 4.2 to 4.6 shall apply.

For the purpose of EMC tests, body worn or hand held transmitters shall be mounted on a non-conductive stand at least

0,8 m from any conducting surface. The EUT and any other equipment required for the performance assessment before,

during, and after the conclusion of the tests, shall be connected in a manner typical of normal intended use.

Whenever the EUT is provided with a detachable antenna, it shall be tested with the antenna fitted in a manner typical

of normal intended use.

For immunity tests, if the equipment is of a category which permits it, a communications link shall be established at the

start of the test and maintained during the test.
The test conditions shall be as follows:

• the transmitter shall be operated at its normal maximum RF output power modulated with a suitable

modulation signal (see clause 4.6.1);

• for stand alone receivers or receivers of transceivers operating in simplex mode, the wanted RF input signal,

coupled to the receiver, shall be modulated with a suitable modulation signal (see clause 4.6.2);

ETSI
---------------------- Page: 8 ----------------------
9 Draft ETSI EN 301 489-9 V2.1.0 (2016-09)

• for duplex transceivers, the wanted RF input signal, coupled to the receiver, shall be modulated with a suitable

modulation signal (see clause 4.6.2). The transmitter shall be operated at its normal maximum output power,

modulated with the test modulation signal, coupled to the transmitter from the output of the receiver (repeater

mode);

• digitally modulated systems shall use a defined interface to convert between analogue and digital domain (and

vice versa).
4.3 Arrangements for test signals
4.3.1 General
The provisions of ETSI EN 301 489-1 [1], clause 4.2 shall apply.
4.3.2 Arrangements for test signals at the input of transmitters

The provisions of ETSI EN 301 489-1 [1], clause 4.2.1 shall apply with the following modifications.

For transmitters designed to operate from an integral or dedicated microphone (see figure 2) it shall be permissible to

use an acoustic coupling device to inject the normal test modulation signal (see figure 3). The acoustic coupling device

may be provided by the manufacturer.

For equipment which can use a variety of audio capsules, the manufacturer shall declare the type of capsule,

e.g. dynamic, electret, or condenser, to be provided with the system. Only one type of capsule shall be tested. All other

capsules shall be deemed as compliant. The transmitter shall be tested at its most sensitive input with the test capsule.

For equipment not designed to use an integral or dedicated microphone, the test signal shall be fed in electrical form to

the most sensitive input socket (see figure 1) using maximum length cables as normally supplied by the manufacturer

with the equipment.

The modulation signal used for the tests shall be a 1 kHz sine wave tone at a level declared by the manufacturer to

obtain 100 % audio modulation.

The manufacturer may provide a suitable companion receiver that can be used to set up a communications link. In this

case a suitable attenuator in the companion receiver input may be necessary, see annex B for further details.

In the case of systems with a digital audio input and outputs this test signal has to be presented via a suitable test fixture

converting the analogue signal to the digital domain and vice-versa. The applicant shall provide details on the interface

and test fixture used for the test.
4.3.3 Arrangements for test signals at the output of transmitters
The provisions of ETSI EN 301 489-1 [1], clause 4.2.2 shall apply.
4.3.4 Arrangements for test signals at the input of receivers

The provisions of ETSI EN 301 489-1 [1], clause 4.2.3 shall apply with the following modifications.

The wanted RF input signal to the receiver should be modulated with a suitable signal corresponding to 100 % audio

modulation (maximum channel loading). If it is not appropriate to provide a modulated RF signal to the receiver, the

test may be performed using an unmodulated wanted RF input signal.

The level and make up of the wanted RF input signal shall be declared by the manufacturer. The level chosen shall be

set to a value 60 dB above the threshold sensitivity of the receiver. Other systems than analogue radio microphones can

define another level more in line with the application. The level used shall be recorded in the test report.

The manufacturer may provide a suitable companion transmitter that can be used to set up a communications link. In

this case a suitable attenuator in the EUT input may be necessary.
