ETSI ETSI EN 300 440-1 V1.3.1 (2001-09) 7 1 Scope The present document applies to Short Range Devices (SRDs) transmitters and receivers: a) transmitters operating in range from 1 GHz to 40 GHz with power levels ranging up to 4W; b) receivers operating in the range from 1 GHz to 40 GHz; The present document contains the technical characteristics for radio equipment and is referencing CEPT/ERC Recommendation for SRDs CEPT/ERC Recommendation 70-03 [1] and ERC Decisions. 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 It is a product family standard which may be completely or partially superseded by specific standards covering specific applications.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, telecommand, telemetry etc. applications; - for all types of modulation; - 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 7.2 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 [1] or ERC Decisions. Table 1: Maximum radiated peak power (e.i.r.p.) Power Class (see note 1) Power level (conducted or radiated) 8 10 mW 9
25 mW 11
100 mW 12
500 mW (see note 2) 13 1 W 14 2 W 14a 4 W (see note 2) NOTE 1: Class designation is based on CEPT/ERC Recommendation 70-03 [1]. NOTE 2: For RFID applications, see annex C of the present document.
On non-harmonized parameters, national administrations may impose conditions on the type of modulation, frequency, channel/frequency separations, maximum transmitter radiated field strength/maximum output current to a defined antenna, duty cycle, equipment marking and the inclusion of an automatic transmitter shut-off facility, as a condition for the issue of an individual or general licence, or as a condition for use under licence exemption. The present document does not require measurements for radiated emissions below 25 MHz. SIST EN 300 440-1 V1.3.1:2003

ETSI ETSI EN 300 440-1 V1.3.1 (2001-09) 14 5.2.1 External test power source During type tests, the power source of the equipment shall be replaced by an external test power source capable of producing normal and extreme test voltages as specified in clauses 5.3.2 and 5.4.2. The internal impedance of the external test power source shall be low enough for its effect on the test results to be negligible. For the purpose of the tests, the voltage of the external test power source shall be measured at the input terminals of the equipment. The external test power source shall be suitably de-coupled and applied as close to the equipment battery terminals as practicable. For radiated measurements any external power leads should be so arranged so as not to affect the measurements. During tests the test power source voltages shall be within a tolerance of < ±1 % relative to the voltage at the beginning of each test. The value of this tolerance can be critical for certain measurements. Using a smaller tolerance will provide a better uncertainty value for these measurements. 5.2.2 Internal test power source For radiated measurements on portable equipment with integral antenna, fully charged internal batteries should be used. The batteries used should be as supplied or recommended by the applicant. If internal batteries are used, at the end of each test the voltage shall be within a tolerance of < ±5 % relative to the voltage at the beginning of each
