scope:
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 nonspeech 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.
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 type of equipment covered by this ETS is handportable stations with integral antennas.
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 draft prETS 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).
