The present document specifies technical characteristics and methods of measurements for Point-to-point (P-P) Digital Fixed Radio Systems (DFRS) operating in frequency bands allocated to Fixed Service (FS) from 1 GHz to 174,8 GHz, corresponding to the appropriate frequency bands from 1,4 GHz to 174,8 GHz as described in relevant annexes B through L. Systems in the scope of the present document are generally intended to operate in full Frequency Division Duplex (FDD) and cover also unidirectional links applications. Time Division Duplex (TDD) applications, when possibly applicable in a specific band, are explicitly mentioned as appropriate in the relevant annexes B through L. Other possible prescriptions, limitations and requirements, for operation in specific bands are also explicitly mentioned, as appropriate, in the relevant annexes B through L. Systems in the scope of the present document are intended to operate only in combination with directive fixed gain antennas respecting the technical requirements in ETSI EN 302 217-4 [6]. Systems in the scope of the present document may be composed by equipment without antennas (see informative annex Q for background) or equipment including integral (but physically detachable) or dedicated antenna. Systems including integral antennas physically undetachable from the radio equipment are not in the scope of the present document (see note 1). NOTE 1: For additional information, the rationale is that the present document as well as ETSI EN 301 126-1 [1] (radio equipment parameters testing) do not provide radiated test methods and ETSI EN 301 126-3-1 [2] (antenna parameters testing) does not provide test methods for undetachable antennas; future revisions could fill this vacancy. NOTE 2: The relationship between the present document and the essential requirements of article 3.2 of Directive 2014/53/EU [i.1] is given in annex A.

The present document details standardized procedures for conformance test of radio interface parameters for Point to Point (PP) equipment used for Digital Fixed Radio Systems (DFRS). Three sets of procedures (for ER, OR and CP) are considered in the scope of the present document: • Procedures for radio parameters relevant to Essential Requirements (ER) and Optional Requirements (OR), relevant to article 3.2 of Directive 2014/53/EU [i.1]. Requirements for these parameters are detailed in ETSI EN 302 217-2 [9]. • Procedures for Complementary Requirements (CP) that, even if not considered "essential" in the light of article 3.2 of Directive 2014/53/EU [i.1], are considered important for the operations of PP equipment. These parameters are detailed in clause 8 of ETSI EN 302 217-1 [8]. The present document is mainly intended to be applied in conjunction with the above equipment relevant standards and will enable commonality of test results, irrespective of the body carrying out the test. However, the present document can be used also in conjunction with other DFRS relevant standards that would refer to the parameters and test methods hereby described. The conformance tests described in the present document are those related to radio specific parameters required directly by the radio equipment relevant standards at antenna ports in conducted test methods. Conformance tests to other boundary standards (e.g. those for system input/output interfaces (i.e. set at X/X' interface, shown in figure 2, and related baseband process) are outside the scope of the present document. Also, tests described in the present document are not applicable to radio equipment with integral antenna of undetachable antenna type requiring radiated test methods.

The present document applies to Digital Fixed Radio Systems (DFRS) in point-to-point operation with integral and external antennas in the frequency range of 1 GHz to 86 GHz corresponding to the appropriate frequency bands 1,4 GHz to 86 GHz as described in ETSI EN 302 217-2 [16], annex B to annex L. The present document summarizes: • all characteristics, principles and, of utmost importance, terms and definitions that are common to all P-P equipment and antennas and its consultation is necessary when using all other parts of ETSI EN 302 217 series; • all system-dependent requirements for Point-to-Point (P-P) equipment. These requirements are introduced in two different clauses sub-sets: - Main requirements are requirements that are also related to the "essential requirements" under article 3.2 of Directive 2014/53/EU [i.1] and further detailed in the Harmonised Standard ETSI EN 302 217-2 [16]. - Complementary requirements are requirements that are not related to essential requirements under article 3.2 of Directive 2014/53/EU [i.1]. Nevertheless they have been commonly agreed for proper system operation and deployment when specific deployment conditions or compatibility requirements are present. Compliance to all or some of these requirements is left to manufacturer decision. Health and safety requirements and EMC conditions and requirements (articles 3.1a and 3.1b of Directive 2014/53/EU [i.1]), as well as other special conditions and requirements (articles 3.3(a) to 3.3(i) of Directive 2014/53/EU [i.1]) are not considered in the ETSI EN 302 217 series.

The present document defines the characteristics and requirements of antennas for point-to-point radio equipment operating in the frequency range from 1 GHz to 174,8 GHz falling within the scope (see note) of ETSI EN 302 217-2 [i.2]. For technical commonalities that range is here divided into sub-ranges as follows: Range 0: 1 GHz to 3 GHz; Range 1: 3 GHz to 14 GHz; Range 2: 14 GHz to 20 GHz; Range 3: 20 GHz to 24 GHz; Range 4: 24 GHz to 30 GHz; Range 5: 30 GHz to 47 GHz; Range 6: 47 GHz to 71 GHz; Range 7: 71 GHz to 86 GHz; Range 8: 92 GHz to 114,25 GHz; Range 9: 130 GHz to 174,8 GHz. The present document is applicable to fixed radio equipment with integral (see note) or dedicated antennas. NOTE: For information, ETSI EN 302 217-2 [i.2] includes in its scope only the use of detachable integral antennas; undetachable integral antennas are not considered due to the present lack of radiated test procedures for the radio equipment parameters. The present document also applies to stand-alone antennas, placed separately on the market. In this case the present document is to be used by radio equipment manufacturers to provide guidance as to the information for the user, as required by article 10 paragraph 8 of Directive 2014/53/EU [i.1], regarding the antenna characteristics required so as the radio equipment, supplied without antenna, can operate as intended in its technical documentation. The present document is applicable to fixed beam antennas, as well as to "self-alignment tracking" antenna, with limited tracking range, so that all requirements in the present document are respected throughout the tracking angle indicated in the technical documentation. The main body of the present document specifies the characteristics that define the various antenna classes, whilst the annexes provide additional information that is useful to both antenna manufacturers and user/installers.

Esta parte de la norma IEC 61094 especifica la configuración geométrica y las características electroacústicas esenciales para los micrófonos de condensador utilizados como patrones de transferencia para la difusión de la trazabilidad de las medidas de presión acústica y para las medidas de presión acústica de alta precisión. Las especificaciones tienen por objeto optimizar la reproducibilidad en la calibración de la sensibilidad a la presión de los micrófonos de medición por comparación en acopladores y cuando los micrófonos de medición están acoplados a un determinado calibrador de sonido o acoplador de comparación, en la gama de frecuencias nominales de 10 Hz a 1 250 Hz, cuando se utiliza el micrófono patrón de transferencia como dispositivo de referencia. Las especificaciones no garantizan que un micrófono de patrón de transferencia pueda utilizarse por encima de 1 250 Hz, ya que la presencia de una rejilla hace que se deteriore la reproducibilidad en el uso previsto. Se incluyen algunas especificaciones para micrófonos de estándar de transferencia a frecuencias más altas porque son necesarias para el uso previsto. Esta parte de la norma IEC 61094 también complementa el sistema mnemotécnico establecido en la norma IEC 61094-1 para clasificar los micrófonos de medición, con el fin de incluir los micrófonos estándar de transferencia.

Este documento explica la aplicación de las normas armonizadas y otras normas CEM para la comercialización de productos combinados con radios únicas o múltiples para demostrar la conformidad con los requisitos esenciales establecidos en el artículo 3, apartado 1, letra a) (salud y seguridad de las personas y los animales domésticos y seguridad de los bienes) de la Directiva sobre equipos radioeléctricos 2014/53/UE ( RED )[1].
