scope:

This standard specifies the minimum performance characteristic and the related methods of measurement for on-site paging transmitters and receivers. Although this ETS covers the general operational aspects of onsite paging systems, it is restricted to the wireless (radio and loop) communications of the service. It is assumed that the radio type of system will operate in the frequency range of 25 MHz to 470 MHz, and loop systems below 150 kHz.

This standard does not cover radiation below 25 MHz, except for the output of loop equipment. It is anticipated that methods of measurements and minimum standards for such radiations will be covered by specifications supporting EMC Directive 89/336 EEC.

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

This standard may be used by accredited test laboratories for type testing of the equipment.

The performance of the equipment submitted for type testing shall be representative of the performance of the corresponding production models.

This standard also contains instructions for the presentation of equipment for type testing purposes.

The types of equipment covered by this standard are as follows:

- base station transmitter (radio and loop);

- base station receivers;

- pocket unit (receiver, transceiver or transmitter).

Annex A: provides information concerning test on-site paging service.

Annex B: provides normative information concerning measuring support for pocket equipment.

Annex C: contains normative specifications for adjacent channel power measurement.

Annex D: is a graphic representation of the normative subclause 10.4.1.3 referring to the limits for spurious radiations of loop receivers.
