Electromagnetic Compatibility and Radio Spectrum Matters (ERM); Short Range Devices; Radio Equipment to Be Used in the 1 GHz to 40 GHz Frequency Range; Part 1: Technical Characteristics and Test Methods
|Publication Date:||1 July 2001|
The present document applies to Short Range Devices (SRDs) transmitters and receivers:
- transmitters operating in range from 1 GHz to 40 GHz with power levels ranging up to 4W;
- receivers operating in the range from 1 GHz to 40 GHz.
The present document contains the technical characteristics for radio equipment and is referencingCEPT/ERC Recommendation for SRDs CEPT/ERC Recommendation 70-03 .
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 It is a product family standard which may be completely or partially superseded by specific standards covering specific applications.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:
- either with a Radio Frequency (RF) output connection and specified antenna, or with an integral antenna;
- for alarms, identification systems, radio-determination,
- for all types of modulation;
- with or without speech.
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 subclause 7.2 are met.
The radio equipment, covered by the classification SRD is divided into several power classes based on maximum output power (see table 1). The power class designation is based on CEPT/ERC Recommendation 70-03 .
The present document does not require measurements for radiated emissions below 25 MHz.
Additional standards or specifications may be required for equipment such as that intended for connection to the Public Switched Telephone Network (PSTN).
