This ETS 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 ETS does not cover radiation below 25 MHz@ except for the output of loop equipment. Additional standards or specifications may be required for equipment intended to interface to the Public Switched Telephone Network (PSTN). This ETS may be used by accredited test laboratories for type testing of the equipment. This ETS also contains instructions for the presentation of equipment for type testing purposes. The types of equipment covered by this ETS are as follows: - base station transmitters (radio and loop)@ with or withclut an external 50?? antenna connector; - base station receivers@ with a permanent 50?? connector; - pocket unit (receiver@ transceiver or transmitter)@ with or without an external 50 ?? antenna connector. Annex A: provides information concerning test sites and general arrangements for measurements involving the use of radiated fields. Annex B: provides information concerning the on-site paging service. Annex C: provides normative information concerning measuring support for pocket equipment. Annex D: contains normative specifications for adjacent channel power measurement. Annex E: is a graphic representation of the normative subclause 10.4.1.3 referring to the limits for spurious radiations of loop receivers. Annex F: contains a list of informative references.
