Page 7ETS 300 683: June 19971ScopeThis European Telecommunication Standard (ETS) covers the assessment of the Short Range Devices(SRD) product family and ancillary equipment in respect of ElectroMagnetic Compatibility (EMC).Technical specifications related to the antenna port and emissions from the enclosure port of the radioequipment are not included in this ETS. Such technical specifications are found in related radio productstandards.This product family EMC Standard may be superseded by specific product EMC standards, covering aspecific application.This ETS specifies the applicable EMC tests, the method of measurements, the limits and the minimumperformance criteria for Short Range Devices, as specified in ETS 300 220-1 [1], I-ETS 300 330 [2]and I-ETS 300 440 [3] depending on the used frequency band, and the associated ancillary equipment.It might be determined from consideration of electrical characteristics of a particular apparatus that sometests are technically inappropriate. In such a case, it is required that the decision and justification not totest these parameters shall be recorded in the test report.The environmental classification used in this ETS refers to the environment classification used in theGeneric Standards EN 50081-1 [4], EN 50082-1 [5], except the vehicular environment class which refersto ISO 7637 [6], [7].The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus atresidential, commercial, light industrial and vehicular environment. The levels however, do not coverextreme cases which may occur in any location but with low probability of occurrence.This ETS may not cover those cases where a potential source of interference which is producingindividually repeated transient phenomena or a continuous phenomena is permanently present, e.g. aradar or broadcast site in the near vicinity. In such a case it may be necessary to use special protectionapplied to either the source of interference or the interfered part or both.Compliance of radio equipment to the requirements of this ETS, does not signify compliance to anyrequirements related to spectrum management or any requirement related to the use of the equipment(licensing requirements).Compliance to this ETS does not signify compliance to any safety requirements. However, it is theresponsibility of the assessor of the equipment that any observation regarding the equipment becomingdangerous or unsafe as a result of the application of the tests of this ETS should be recorded in the testreport.This ETS does not cover specific requirements for safety critical applications.2Normative referencesThis ETS incorporates by dated and undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listedhereafter.

The test conditions shall be recorded in the test report.The test configuration shall be as close to normal intended use as possible and shall be recorded in thetest report.Whenever the Equipment Under Test (EUT) is provided with a detachable antenna, the EUT shall betested with the antenna fitted in a manner typical of normal intended use, unless specified otherwise.For the purpose of this ETS the short range radio devices are divided into three types of equipment, basedon the technical nature of the primary function.Table 1Equipment TypeTechnical nature of the primary functionITransfer of messages (digital or analogue signals)IITransfer of audio (speech or music)IIIOthers4.2Normal test modulationFor equipment type I the carrier shall be modulated with a test signal, representing a practical selection ofthe usable selective messages/commands. The agreed test signal may be formatted and may containerror detection and correction. Where transmitters do not have a modulation input port, the internalequipment modulation is used.For equipment type II (audio equipment):-the wanted input signal of the receiver under test shall be set to the nominal frequency of thereceiver, modulated with a sinusoidal audio frequency of 1 000 Hz having a modulationcorresponding to 60 % of the peak system modulation;-the transmitter under test shall be modulated with a sinusoidal audio frequency of 1 000 Hz havinga modulation corresponding to 60 % of the system peak modulation.For equipment type III the manufacturer shall specify the normal test modulation, if any.4.3Arrangements for test signals at the input of the transmitterThe transmitter shall be operated at its maximum rated output, modulated with normal test modulation asspecified for that type of equipment (subclause 4.2).If internal equipment modulation is not available, the signal generator to be used for the modulation signalshall be located outside the test environment and connected to the modulation input of the transmitter viaappropriate means. Adequate measures shall be taken to protect the measuring equipment from theeffect of all the radiated fields within the test environment.4.4Arrangements for test signals at the output of the transmitterThe measuring equipment used to monitor the output signal of the transmitter shall be located outside thetest environment. Adequate measures shall be taken to protect the measuring equipment from the effectof all the radiated fields within the test environment.SIST EN 300 683:1998

Page 11ETS 300 683: June 1997The manufacturer may provide a suitable companion receiver that can be used to receive messages or toset up a communication link.Where the transmitter incorporates an external Radio Frequency (RF) antenna connector, the outputsignal of the transmitter, shall be coupled to the receiving/measuring equipment via a shieldedtransmission line such as a coaxial cable. Adequate measures shall be taken to minimize the effect ofunwanted common mode currents on the external conductor of the transmission line at the point of entryto the transmitter.In case of an equipment not provided with an external RF connector, the output signal of the transmittershall be coupled to another antenna located within the test environment. This antenna shall be coupled tothe receiving/measuring equipment outside the test environment.4.5Arrangements for test signals at the input of the receiverFor receivers, the wanted RF input signal, coupled to the receiver, shall be modulated with normal testmodulation as specified for that type of equipment (subclause 4.2).The source of the wanted input signal shall be located outside the test environment and the level shall bechosen to a value significantly above the threshold sensitivity but below the overload characteristics of thereceiver.The manufacturer may provide a suitable companion transmitter that can be used to transmit messagesor to set up a communication link.Where the receiver incorporates an external RF antenna connector, the wanted input signal shall becoupled to the wanted RF signal source via a shielded transmission line, such as a coaxial cable.Adequate measures shall be taken to minimize the effect of unwanted common mode currents on theexternal conductor of the shielded transmission line at the point of entry to the receiver.In case of an equipment not provided with an external RF connector the wanted input signal, shall bepresented to the receiver from another antenna located within the test environment. This antenna shall becoupled to the wanted RF signal source.4.6Arrangements for test signals at the output of the receiverFor equipment type I it shall be possible to assess the performance of the equipment by appropriatelymonitoring (observing) the receiver reaction.For equipment type II the measuring equipment used to monitor the output signal of the receiver shall belocated outside the test environment. Adequate measures shall be taken to protect the measuringequipment from the effect of all the radiated fields within the test environment.For equipment type III, see subclause 5.4.4.7Arrangements for testing transmitter and receiver together (as a system)The transmitter and receiver may be tested together, if appropriate (size of equipment etc.). In this casethe transmitter and the receiver shall be located inside the test environment and shall be exposed at thesame time to the EMC phenomena. Instead of coupling the output signal of the transmitter (subclause 4.4)to the measuring equipment outside the test environment, this signal shall be coupled, inside the testenvironment, to input of the receiver (subclause 4.5), via an attenuator, if required, to prevent overload ofthe receiver.4.8Exclusion bandsExclusion bands are frequency bands where RF immunity tests are not performed while testing the EUT.Exclusion bands are defined in the following subclauses.SIST EN 300 683:1998

Page 12ETS 300 683: June 19974.8.1Exclusion bands for receiversThe exclusion band for receivers (including receivers part of transceivers) intended to be used in achannellized frequency band, is determined as follows:-for receivers capable of operating on only one single frequency and not having an alignment range,the lower frequency of the exclusion band is the lower frequency of the used frequency channelminus the extension value given in table 2, and the upper frequency of the exclusion band is theupper frequency of the used frequency channel plus the extension value given in table 2. Thecalculated extension value shall be based on the operating frequency;-for receivers capable of operating on only one single frequency and having an alignment range, thelower frequency of the exclusion band is the lower frequency of the alignment range minus theextension value given in table 2, and the upper frequency of the exclusion band is the upperfrequency of the alignment range plus the extension value given in table 2. The calculatedextension values shall be based on the centre frequency of the alignment range. However, if thealignment range is more than 10 % of the upper frequency of the alignment range the calculatedvalue shall be based on 10 % of the upper value of the alignment range;-for receivers capable of operating on more than one frequency in an operating frequency band thewidth of which is less than 20 % of the centre frequency of the operating band, the lower frequencyof the exclusion band is the lower frequency of the operating band minus the extension value givenin table 2, and the upper frequency of the exclusion band is the upper frequency of the operatingband plus the extension value given in table 2. The calculated extension value shall be based onthe centre frequency of the operating band;-for receivers capable of operating on a number of frequencies over a frequency band wider than theband specified above, immunity tests shall be made over a selected number of test frequencies.The selected test frequencies shall be located at three evenly spaced points per logarithmic decadeof the frequency band. For each test frequency the lower frequency of the exclusion band is thelower frequency of the used test frequency channel minus the extension value given in table 2, andthe upper frequency of the exclusion band is the upper frequency of the used test frequencychannel plus the extension value given in table 2. The calculated extension value shall be based onthe used test frequency.For wide band receivers, i.e. receivers operating in a non-channellized frequency band, the lowerfrequency of the exclusion band is the lower frequency of the intended operating frequency band minusthe extension value given in table 2 and the upper frequency of the exclusion band is the upper frequencyof the intended operating band plus the extension value given in table 2, or the total exclusion band istwice the intended operating frequency band of the receiver centred around the centre frequency of theintended operating band, whichever is greater.Table 2Operating frequencyExtension value< 5 MHz20 %=> 5 MHz and < 80 MHz10 % or 1 MHz, whichever is greater=> 80 MHz5 % or 10 MHz, whichever is greater4.8.2Exclusion band for transmittersFor transmitters operating, or intended to operate, in a channellized frequency band, the exclusion band isthree times the maximum occupied bandwidth allowed for that service, centred around the operatingfrequency.For wide band transmitters, i.e. transmitters in a non-channellized frequency band, the exclusion band istwice the intended operating frequency band centred around the centre frequency of the intendedoperating frequency band.In case the receiver and transmitter are tested together as a system (subclause 4.7) the exclusion banddefined for receivers or the exclusion band defined for transmitters shall be used, whichever is greater.SIST EN 300 683:1998

Page 13ETS 300 683: June 19974.9Narrow band responses of receiversResponses of receivers or receivers of transceivers occurring during the test at discrete frequencies whichare narrow band responses (spurious responses) are identified by the following method.If during the test the unwanted signal causes non compliance of the receiver with the specifiedperformance level (clause 6), it is necessary to establish whether this non compliance is due to a narrowband response or to a wideband phenomenon. Therefore, the unwanted signal frequency is increased byan amount equal to twice the nominal 6 dB bandwidth of the receiver pre-demodulation filter, or ifappropriate, the bandwidth over which the apparatus is intended to operate, as declared by themanufacturer. The test is repeated with the frequency of the unwanted signal decreased by the sameamount.If the receiver is then in compliance with the specified performance level (clause 6), the response isconsidered as a narrow band response.If the receiver still does not comply with the specified performance level (clause 6), this may be due to thefact that the offset has made the frequency of the unwanted signal correspond to the frequency of anothernarrowband response. Under these circumstances the procedure is repeated with the increase anddecrease of the frequency of the unwanted signal adjusted two and a half times the bandwidth previouslyreferred to. If the receiver still does not comply with the specified performance level, the phenomena isconsidered wideband and therefore an EMC problem and the equipment fails the test.Narrow band responses shall be disregarded.5Performance assessment5.1GeneralThe manufacturer shall at the time of submission of the equipment for test, supply the followinginformation which shall be recorded in the test report:-the primary functions of the radio equipment to be evaluated during and after the EMC tests;-the intended functions of the EUT which shall be in accordance with the documentationaccompanying the equipment;-the ancillary equipment to be combined with the radio equipment for testing;-the user control functions and stored data that are required for normal operation and the method tobe used to assess whether these have been lost after EMC stress;-an exhaustive list of ports, classified as either power or signal/control. Power ports shall further beclassified as AC or DC power;-the bandwidth of the IF filter;-the applicable equipment type according table 1 (subclause 4.1).The performance assessment is dependent on the equipment type (subclause 4.1).For all types of equipment the performance assessment is based on:-maintenance of function(s);-the way the eventual loss of function(s) can be recovered;-unintentional behaviour of the EUT.SIST EN 300 683:1998

Page 14ETS 300 683: June 1997Additionally:-for equipment type II the degradation in performance during the radio frequency immunity tests isexpressed in a minimum SINAD decibel value;-for equipment type III the manufacturer shall specify the way the degradation in performance shouldbe measured and expressed.5.2Additional assessments for portable and mobile equipmentPortable equipment, or combinations of equipment, declared as capable of being powered for intendeduse by the main battery of a vehicle shall additionally be considered as a vehicular mobile equipment.Portable or mobile equipment, or combinations of equipment, declared as capable of being powered forintended use by AC mains shall additionally be considered as a base station equipment.5.3Ancillary equipmentAt the manufacturers discretion an ancillary equipment may be:-declared compliant to an appropriate harmonized EMC standard;-tested separately from a receiver or transmitter to all the applicable immunity and emission clausesof this ETS;-tested with it connected to a receiver or transmitter, in which case compliance shall bedemonstrated to the appropriate clauses of this ETS.In each case, compliance enables the ancillary equipment to be used with different receivers ortransmitters.5.4Equipment of special natureIn the case of ancillary equipment tested on a stand alone basis and/or radio equipment of a specializednature or equipment type III the manufacturer shall define the method of test to determine the acceptablelevel of performance or degradation of performance during and/or after the test. Under thesecircumstances the manufacturer shall also provide the following information:-the pass/failure criteria for the equipment;-the method of observing a degradation of performance of the equipment.The degradation of performance assessment which shall be carried out during and/or at the conclusion ofthe tests, shall be simple, but at the same time give adequate proof that the primary functions of theequipment are operational.6Performance criteria6.1Classification of equipmentThe product family of short range radio devices is divided into three classes of equipment, each having itsown set of minimum performance criteria. This classification is based upon the impact on persons and/orgoods in case the equipment does not operate above the specified minimum performance level underEMC stress.SIST EN 300 683:1998
