scope:

This ETS is intended to specify the minimum performance and the methods of measurement of radio equipment for use in the land mobile service as specified in this scope. Clause 5 provides the corresponding limits. These limits have been chosen to ensure an acceptable grade of service and to minimise harmful interference to other equipment and services. They are based on the interpretation of the measurement results described in subclause 4.3.

This ETS covers the minimum characteristics considered necessary in order to make the best use of the available frequencies. It does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable. It applies to non-speech and to the non-speech part of combined speech/non-speech equipment with integral antennas, used in constant envelope angle modulation systems in the land mobile service, operating on radio frequencies between 30 MHz and 1 000 MHz, with channel separations of 12,5 kHz, 20 kHz and 25 kHz.

This ETS, which is based upon CEPT Recommendation T/R 24-01 annex VI [1], is a general standard which may be superseded by specific standards covering specific applications.

In this ETS, a non-speech radio equipment is defined as a radio equipment transmitting a signal to initiate a specific response in the receiver. The equipment comprises a transmitter and associated encoder and/or a receiver and associated decoder. The encoder and/or decoder may be a separate piece of equipment, in which case compliance to this ETS covers the combination of encoder and/or decoder and transmitter and/or receiver equipment.

In this ETS different requirements are given for the different radio frequency bands, channel separations, environmental conditions and types of equipment, where appropriate.

The measurement methods have been adapted from ETR 027 [5] where possible.

The type of equipment covered by this ETS is handportable stations with integral antennas.

This ETS is complementary to I-ETS 300 219 [2] which covers radio equipment with an internal or external RF connector transmitting signals to initiate a specific response in the receiver, for use in the land mobile service. It is primarily intended for omnidirectional applications.

For combined speech/non speech equipment this ETS is complementary to ETS 300 296 [8] which covers radio equipment using integral antennas for use in the land mobile service intended primarily for analogue speech.

Channel separations, maximum transmitter effective radiated power, the type and characteristics of modulation and the inclusion of automatic transmitter shut-off facility may be conditions required for the issue of a licence by the appropriate administration.

Equipment which also includes an external or internal RF connector should be type tested to the requirements of ETS 300 086 [3] and/or I-ETS 300 219 [2] using this connector.

In the case of combined speech/non-speech equipment the speech part should be tested to the requirements of ETS 300 296 [8] and additionally the tests described in the following subclauses of this ETS should be carried out:

- subclause 8.3: adjacent channel power;

- subclause 9.1: average usable sensitivity (responses).

These requirements also apply for equipment with an analogue output facility provided for test purposes only.

Where an equipment has already been type approved to ETS 300 296 [8], and is resubmitted for type testing to this ETS, additionally the tests described in the following subclauses of this ETS should be carried out:

- subclause 8.3: adjacent channel power;

- subclause 8.4: radiated spurious emissions;

- subclause 9.1: average usable sensitivity (responses).

Radio equipment for data is covered by I-ETS 300 113 [4] and prETS 300 390 [9].

Additional standards or specifications may be required for equipment such as that intended for connection to the Public Switched Telephone Network (PSTN).

This ETS does not cover requirements for radiated emissions below 30 MHz.

This ETS may also be used by accredited test laboratories for the assessment of the performance of the equipment. The performance of the equipment submitted for type testing should be representative for the performance of the corresponding production model. In order to avoid any ambiguity in that assessment, this ETS contains instructions for the presentation of equipment for type testing purposes (clause 4), conditions (clause 6) and measurement methods (clauses 8 and 9).
