ÖNORM EN 300330-1 V 1.5.1

The present document applies to Short Range Devices (SRDs) transmitters and receivers: transmitters operating in the range from 9 kHz to 25 MHz; and inductive loop transmitters operating from 9 kHz to 30 MHz; receivers operating from 9 kHz to 30 MHz. 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 It is a product family standard which may be completely or partially superseded by specific standards covering specific applications.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 generic SRDs including: inductive loop systems; systems with an antenna connector and/or an integral antenna; systems for alarm, identification, telecommand, telemetry, etc.; and/or 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. If a system includes transponders, these are measured together with the transmitter. All types of modulation for radio devices are covered by the present document, provided the requirements of clause 7.3 are met. The radio equipment, covered by the classification SRD is divided into several classes based on the maximum radiated magnetic field strength. The field strength designation in the present document is based on CEPT/ERC/Recommendation 70-03 [3] and National SRD-frequency designations. Three types of measuring methods are defined in the present document due to the varied nature of the antenna types for equipment used in this band. One method measures the RF carrier current, another measures the radiated H-field and the third the conducted power. The present document covers requirements for radiated emissions below as well as above 30 MHz. Additional standards or specifications may be required for equipment such as that intended for connection to the Public Switched Telephone Network (PSTN).
