scope:

This I-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 constant envelope angle modulated equipment for use 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.

In this I-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 shall comprise of 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 I-ETS covers the encoder and/or decoder in connection with the transmitter and/or receiver equipment.

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

The types of equipment covered by this I-ETS are as follows:

- Base station: equipment fitted with an antenna socket;

- Mobile station: equipment fitted with an antenna socket;

- Handportable stations:

a) fitted with an antenna socket; or

b) without an external antenna socket (integral antenna equipment) but fitted with a permanent internal or a temporary internal 50 Ω RF connector which allows access to the transmitter output and the receiver input.

For the type of equipment defined in b), the additional measurements which shall be made using the equipment antenna connected to the station (and not using any connector) are as follows:

- subclause 9.3: Transmitter effective radiated power;

- subclause 9.5.4: Transmitter radiated spurious emissions;

- subclause 10.3: Receiver maximum usable sensitivity (response, field strength);

- subclause 10.9.4: Receiver radiated spurious radiations.

Handportable equipment without an external or internal RF connector and without the possibility of having a temporary internal 50 Ω RF connector is not covered by this I-ETS.

In the case of combined speech/non-speech equipment the speech part shall be tested to ETS 300 086 [2] and additionally the tests described in the following subclauses of this I-ETS shall be carried out:

- subclause 9.4: Adjacent channel power;

- subclause 10.2: Maximum usable sensitivity (responses,conducted);

- subclause 10.3: Maximum usable sensitivity (responses, field strength).

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 300 086 [2], and is resubmitted for type testing to this I-ETS, additionally the tests described in the following subclauses of this I-ETS shall be carried out:

- subclause 9.4: Adjacent channel power;

- subclause 10.2: Maximum usable sensitivity (responses, conducted);

- subclause 10.3: Maximum usable sensitivity (responses, field strength);

- subclause 9.5: Spurious emissions.
