Electromagnetic compatibility and Radio spectrum Matters (ERM); Short Range Devices (SRD); Radio equipment to be used in the 25 MHz to 1 000 MHz frequency range with power levels ranging up to 500 mW; Part 1: Technical characteristics and test methods (V1
The present document applies to short range device radio transmitters and receivers: 1) transmitters in the range from 25 MHz to 1 000 MHz and with power levels ranging up to 500 mW; 2) receivers in the range from 25 MHz to 1 000 MHz. The present document contains the technical characteristics for radio equipment referencing CEPT/ERC Decisions and Recommendation CEPT ERC/Recommendation 70-03 [5]. The present document does not necessarily include all the characteristics which may be required by a user@ nor does it necessarily represent the optimum performance achievable. It is a product family standard which may be completely or partially superseded by specific standards covering specific applications. The present document applies to short range devices: - either with a Radio Frequency (RF) output connection and/or with an integral antenna; - for alarms@ identification@ telecommand@ telemetry@ etc.@ applications; - with or without speech. When selecting parameters for new SRDs@ which may have inherent safety of human life implications@ manufacturers and users should pay particular attention to the potential for interference from other systems operating in the same or adjacent bands. The present document covers fixed stations@ mobile stations and portable stations. In the present document requirements are given for the different frequency bands@ channel separations etc.@ where appropriate. All types of modulation are covered@ in the present document@ provided the requirements of subclauses 8.5 or 8.6@ whichever is applicable@ are met. The radio equipment@ covered by SRDs is divided into several power classes based on maximum output power. The power class designation is based on CEPT/ERC Recommendation 70-03 [5]. For non-harmonized parameters@ national regulatory conditions can apply regarding the type of modulation@ channel/frequency separations@ maximum transmitter output power/effective radiated power@ duty cycle@ equipment marking and the inclusion of an automatic transmitter shut-off facility as a condition of the issue of an individual or general licence@ or@ as a condition of use under licence exemption. The extreme temperature ranges are fixed and are given in subclause 5.4.1.2. In the case of systems employing transponders@ the transponders should be measured together with the associated transmitter
