The present document has been produced by ETSI in response to a mandate from the European Commission issued under Council Directive 98/34/EC [i.5] (as amended) laying down a procedure for the provision of information in the field of technical standards and regulations. The present document is intended to become a Harmonized Standard, the reference of which will be published in the Official Journal of the European Communities referencing the Directive 1999/5/EC [i.6] of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity ("the R&TTE Directive"). Technical specifications relevant to Directive 1999/5/EC [i.6] are given in annex A. The Euroloop transmission system operates in accordance with ERC Recommendation 70-03, annex 4. These specifications are complementary with the system and interoperability requirements for these devices established under Commission Decision 2004/447/EC [i.7].

Introduction The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to cover all radio and telecommunications terminal equipment within the scope of the R&TTE Directive. The modular structure is shown in EG 201 399 [i.2]. The Euroloop communication system is defined by the specifications of the UNISIG consortia [i.3]. SIST EN 302 609 V1.1.1:2009

ETSI ETSI EN 302 609 V1.1.1 (2008-11) 6 1 Scope The present document covers the technical requirements for radio transmitters and receivers used in the Euroloop transmission system. The system is only used in railway systems. It applies to the following two equipment units as is shown in figure 1: • The On-Board Equipment (OBE) receiving the Euroloop signal and the OBE comprises a receiver fitted with a dedicated antenna. • The Track-Side Equipment (Euroloop) transmitting the Euroloop signal that is always installed in an inner or outer foot of a rail. AntennaTrain Control SystemLine side Electronic UnitInterlockingEuroloop cablewake-up Receiver Transmitter Figure 1: Euroloop situation on railway track The Euroloop comprises DSSS-BPSK-modulated transmitter fitted with a dedicated antenna. It is always switched on but is only transmitting in the presence of a train. These radio equipment types are capable of operating at the following frequencies as given below in table 1. Table 1: Radiocommunications service frequency bands

The test conditions and procedures shall be as specified in clauses 5.2 to 5.6. 5.2 Test power source The OBE and Euroloop equipment shall be tested using the appropriate test power source. The test power source used shall be stated in the test report. During the tests, the power source of the equipment shall be replaced by an external test power source capable of producing normal test voltages as specified in clauses 5.3.2. The internal impedance of the external test power source shall be low enough for its effect on the test results to be negligible.

For radiated measurements any external power leads should be so arranged so as not to affect the measurements. SIST EN 302 609 V1.1.1:2009

ETSI ETSI EN 302 609 V1.1.1 (2008-11) 11 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. 5.3 Normal test conditions 5.3.1 Normal temperature and humidity The normal temperature and humidity conditions for tests shall be any convenient combination of temperature and humidity within the following ranges: • temperature: +15 °C to +35 °C; • relative humidity: 20 % to 75 %.

For the purpose of the present document, the nominal voltage shall be the declared voltage, or any of the declared voltages, for which the equipment was designed. The frequency of the test power source corresponding to the ac mains shall be between 49 Hz and 51 Hz. 5.3.2.2 Other power sources For operation from other power sources, the normal test voltage shall be that declared by the equipment provider and agreed by the test laboratory.

If equipment has several optional features that are considered to affect directly the RF parameters then tests need only be performed on the equipment configured with the considered worst case combination of features as declared by the manufacturer. The tests shall be performed as radiated - and conducted test using the appropriate measurement procedures. The manufacturer shall provide one or more samples of the equipment, as appropriate for testing. Additionally, technical documentation and operating manuals, sufficient to make the test, shall be supplied. SIST EN 302 609 V1.1.1:2009

ETSI ETSI EN 302 609 V1.1.1 (2008-11) 12 5.6 Measuring receiver The term "measuring receiver" refers to a spectrum analyser. The bandwidth and detector type of the measuring receiver are given in table 2 unless otherwise specified. Table 2: Measuring receiver Frequency: (f) Detector type Spectrum analyzer bandwidth 9 kHz ≤ f < 150 kHz RMS 300 Hz 150 kHz ≤ f < 30 MHz RMS 10 kHz 30 MHz ≤ f ≤ 1 000 MHz RMS 100 kHz

6 Measurement uncertainty The interpretation of the results recorded in the test report for the measurements described in the present document shall be as follows: • the measured value related to the corresponding limit shall be used to decide whether equipment meets the requirements of the present document; • the value of the measurement uncertainty for the measurement of each parameter shall be separately included in the test report; • the value of the measurement uncertainty should be, for each measurement, equal to or lower than the figures in table 3. Table 3: Absolute measurement uncertainties: maximum values Parameter Uncertainty Radiated field strength ±6 dB Conducted RF power ±1,25 dB Temperature ±1 °C Humidity ±10 %

For the test methods, according to the present document, the measurement uncertainty figures shall be calculated in accordance with TR 100 028 [1] and shall correspond to an expansion factor (coverage factor) k = 1,96 or k = 2 (which provide confidence levels of respectively 95 % and 95,45 % in the case where the distributions characterizing the actual measurement uncertainties are normal (Gaussian). Table 4 is based on such expansion factors. The particular expansion factor used for the evaluation of the measurement uncertainty shall be stated. TR 102 273 [i.1] provides further information concerning the usage of test sites. 7 Test procedures for essential radio test suites 7.1 OBE unwanted emissions

For the test conditions, see clause 5.1. The emissions shall be measured over the frequency range 1 MHz to 1 000 MHz. At each frequency at which a relevant spurious signal is detected the OBE under test and the test antenna shall be rotated around the vertical axle until maximum field strength is indicated on the measuring receiver. This level shall be noted. SIST EN 302 609 V1.1.1:2009

ETSI ETSI EN 302 609 V1.1.1 (2008-11) 13 For measuring equipment calibrated in dBμV/m, the reading should be reduced by 51,5 dB to be converted to dBμA/m or vice-versa. The spectrum analyser shall be configured as follows unless otherwise stated: • Resolution bandwidth: In accordance with table 2 in clause 5.6. • Video bandwidth: Not less than the resolution bandwidth. • Detector mode: Quasi Peak. The OBE unwanted emissions are measured: Step 1 For frequencies below 30 MHz the H-field strength shall be measured at 10 m distance by using Quasi Peak detector and the resolution bandwidth as given in table 2 of clause 5.6. The results are recorded in the test report as the total field strength.

Where a measurement distance of 10 m is not practical, e.g. due to physical size of the equipment including the antenna or with use of special field cancelling antenna, then other distances may be used. When another distance is used, the distance used and the field strength value measured shall be stated in the test report. In this cas
