Introduction The present document is intended to specify the minimum performance characteristics and the methods of measurement for Wireless Video Links (WVL) operating in the 1,3 GHz to 50 GHz frequency band. The present document provides the necessary parameters for equipment to obtain common approval throughout Europe. It also is intended to make it easier for the frequency management authorities to find harmonized frequency allocations. Common technical specifications and harmonized frequency allocations are expected to reduce greatly the present problems of interference and illegal use. The present document is a testing standard based on spectrum utilization parameters and does not include performance characteristics that may be required by the user or requirements for interfacing equipment. In preparing the present document, much attention has been given to assure a low interference probability, while at the same time allowing a maximum flexibility and service to the end-user.

1 Scope The present document covers the minimum characteristics considered necessary in order to make the best use of the available frequencies. It does not necessarily include all the characteristics that may be required by a user, nor does it necessarily represent the optimum performance achievable. The present document applies to terrestrial wireless digital video link equipment operating on radio frequencies above 1,3 GHz. It does not preclude any digital modulation technique, provided that the modulated signal lies within the prescribed limits. Instructions for the presentation of equipment for testing purposes are included. Electromagnetic Compatibility (EMC) requirements are covered by EN 301 489-28 (see Bibliography). ES 202 239 [8] specifies the reference receiver performance parameters, which are required for the purpose of spectrum planning and methods of investigation including resolving interference issues. These parameters play an important role in the frequency planning and the respective compatibility analysis performed by responsible national administrations. The present document contains instructions for the presentation of equipment for testing purposes. Transmitter Power limits are defined in the terms and conditions of the users operating licence. Refer to annex C for recommended frequency ranges (ERC/REC 25-10 [2] annex 2). The user categories covered, are as follows: • Category 1: typically used by broadcasters and programme-makers. Users require the highest video contribution quality and or minimum processing delay times to allow both real time inserts into programmes and easy accurate editing. These users normally operate on licensed frequencies. • Category 2: typically used by professional and business. Users have quality requirements similar to above but are maybe not concerned with delay issues that affect the broadcaster and can, therefore, operate within a smaller spectrum mask. • Category 3: typically used by industrial users. Examples include civil and industrial users, emergency services, automobile associations, the utility industries, etc, who need the good quality available from digital-based systems and who operate on licensed allocations. • Category 4: typically used by industrial users including industrial security. Most of these systems could operate either in ISM bands or frequencies specifically allocated for the purpose. • Category 5: typically used by consumers. Caters for consumers, hobbyists and amateur users. The proposed 5 MHz mask can be subdivided into 2 × 2,5 for two way visual communication and is primarily intended for indoor use.
The maximum allowable channel bandwidths for the equipment covered by the present document are shown in table 1. Table 1: Maximum allowable channel bandwidth Equipment Maximum allowable Category 1 Category 2 Category 3 Category 4 Category 5 20 MHz 10 MHz 10 MHz 10 MHz 5 MHz

The internal impedance of the 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 power source shall be measured at the input terminals of the equipment. For battery-operated equipment, the battery may be removed and the test power source shall be substituted, suitably decoupled and applied as close to the equipment battery terminals as practicable. For radiated measurements any external power leads should be arranged so as not to affect the measurements. If necessary the external power supply may be replaced with the equipment's own internal batteries at the required voltage, this shall be stated on the test report. If the equipment is provided with a power cable or power socket, the test voltage shall be that measured at the point of connection of the power cable to the equipment. During tests the 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 provides a better uncertainty value for these measurements. If internal batteries are used, at the end of each test the voltage shall be within a tolerance of < ±1 % relative to the voltage at the beginning of each test. 5.3 Normal test conditions 5.3.1 Normal temperature and humidity The manufacturer shall supply with the equipment documentation defining normal operational environmental conditions, including temperature and humidity operating ranges. This information should be included in the user manual. 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 %. When it is impracticable to carry out tests under these conditions, a note to this effect, stating the ambient temperature and relative humidity during the tests, shall be added to the test report. 5.3.2 Normal test power source voltage 5.3.2.1 Mains voltage The normal test voltage for equipment to be connected to the mains shall be the nominal mains voltage. For the purpose of the present document, the nominal voltage shall be the declared mains voltage, or any of the declared mains voltages, for which the equipment was designed. The frequency of the test power source corresponding to the alternating current (ac) mains shall be between 49 Hz and 51 Hz. 5.3.2.2 Other power sources For operation from other power sources or types of battery (primary or secondary), the normal test voltage shall be that declared by the equipment manufacturer and agreed by the test laboratory. The values shall be stated in the test report. 5.4 Extreme test conditions The following tests are required to ensure that no harmful interference is caused under extreme conditions. Refer to clause 5.3 for normal operating conditions (as declared by the manufacturer). SIST EN 302 064-1 V1.1.1:2005

ETSI ETSI EN 302 064-1 V1.1.1 (2004-04) 14 5.4.1 Extreme temperatures For tests at extreme temperatures detailed in table 2, measurements shall be made in accordance with the procedures specified in clause 5.4.1.1. Table 2: Extreme temperature ranges General: -20°C to +55°C Portable equipment: -10°C to +55°C Equipment for normal indoor use: 0°C to +55°C NOTE: The term "equipment for normal indoor use" is taken to mean that the room temperature is controlled and the minimum indoor temperature is equal to or greater than 5°C.
5.4.1.1 Procedures for tests at extreme temperatures Before measurements are made the equipment shall have reached thermal balance in the test chamber. The equipment shall be switched off during the temperature stabilizing period. If the thermal balance is not checked by measurements, a temperature stabilizing period of at least one hour shall be allowed. The sequence of measurements shall be chosen and the humidity content in the test chamber shall be controlled so that excessive condensation does not occur. Before tests at the higher temperatures, the equipment shall be placed in the test chamber and left until thermal balance is attained. The equipment shall then be switched on for one minute in the transmit condition, after which the equipment shall meet the specified requirements. For tests at the lower extreme temperature the equipment shall be left in the test chamber until thermal balance is attained, then switched to the standby or receive condition for one minute after which the equipment shall meet the specified requirements. 5.4.2 Extreme test power source voltages 5.4.2.1 Mains voltage The extreme test voltages for equipment to be connected to an ac mains source shall be the nominal mains voltage ±10 %.
The frequency of the test power source corresponding to the ac mains shall be between 49 Hz and 61 Hz. 5.4.2.2 Rechargeable battery power sources When the radio equipment is intended for operation from rechargeable cells, the extreme test voltage shall be 1,3 and 0,9 times the nominal voltage of the battery. For other types of battery the lower extreme test voltage for discharged condition shall be declared by the equipment manufacturer. 5.4.2.3 Power sources using other types of batteries The lower extreme test voltages for equipment with power sources using primary batteries shall be as follows: • for Leclanché or lithium type of battery: - 0,85 times the nominal voltage of the battery; • for mercury type of battery: - 0,9 times the nominal voltage of the battery; • for other types of primary batteries: - end-point voltage declared by the equipment manufacturer.
