1 Scope The present document, together with EN 301 489-1 [1], covers the assessment of equipment meeting Phase 2, and Phase 2+ requirements of the GSM and DCS digital cellular radio telecommunications systems and ancillary equipment in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port and emissions from the enclosure port of radio equipment (base station (BTS), ancillary RF amplifiers and GSM repeaters) are not included in the present document. Such technical specifications are found in the relevant product standards for the effective use of the radio spectrum. The present document specifies the applicable test conditions, performance assessment and performance criteria for GSM and DCS digital cellular radio equipment forming part of the Base Station System (BSS), ancillary RF amplifiers, for transmission and/or reception, GSM repeaters and associated ancillary equipment.
Examples of Base station radio, ancillary RF amplifiers and repeaters covered by the present document are given in annex A. The present document is not applicable to equipment, which forms part of the GSM Network Subsystem (NSS), including Mobile services Switching Centres (MSC), Echo Cancellers (EC) and Operations and Maintenance Centres (OMC). In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and EN 301 489-1 [1], the provisions of the present document take precedence. The environment classification and the emission and immunity requirements used in the present document are as stated in EN 301 489-1 [1], except for any special conditions included in the present document. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.

Further product related test conditions for GSM base stations are specified in the present document.
4.1 General For emission and immunity tests the test modulation, test arrangements, etc., as specified in the present document, clauses 4.2 to 4.5 shall apply. For an EUT which contains more than one BTS, it is sufficient to perform tests relating to connectors of each representative type of the BTS forming part of the EUT. For test purposes, any integral antenna shall be disconnected from the BTS, and any antenna connector shall be correctly terminated, either by connection to the test equipment or to an appropriate non-radiating load. Precautions should be taken to ensure that the cables connecting antenna connectors to test equipment or termination do not influence the test results. 4.2 Arrangements for test signals The provisions of EN 301 489-1 [1], clause 4.2 shall apply.

ETSI ETSI EN 301 489-8 V1.2.1 (2002-08) 9
4.2.1 Arrangements for test signals at the input of transmitters The provisions of EN 301 489-1 [1], clause 4.2.1 shall apply with the following modification. A communication link shall be set up between the EUT and the test system using the A or Abis interface, or an equivalent interface which carries the information to be transmitted by the air interface. 4.2.2 Arrangements for test signals at the output of transmitters The provisions of EN 301 489-1 [1], clause 4.2.2 shall apply with the following modification. The wanted RF output signal nominal frequency shall be selected by setting the ARFCN to an appropriate number, e.g. channel M as defined in TS 101 087 [9]. All transmitters in the EUT shall be operated at the maximum rated output power, modulated with normal test modulation (see clause 4.5). A communication link shall be established. 4.2.3 Arrangements for test signals at the input of receivers The provisions of EN 301 489-1 [1], clause 4.2.3 shall apply with the following modification. The source of the wanted RF input signal shall be at a nominal value of -47 dBm. 4.2.4 Arrangements for test signals at the output of receivers The provisions of EN 301 489-1 [1], clause 4.2.4 shall apply with the following modification. A communication link shall be set up between the EUT and the test system using the A or Abis interface, or an equivalent interface which carries the information to be transmitted by the air interface. 4.2.5 Arrangements for testing transmitter and receiver together (as a system) For the immunity tests of base stations including duplex filters, the wanted input signal, coupled to the receiver, shall be modulated with normal test modulation (see clause 4.5). The transmitter(s) shall be operated at the maximum rated output power. A communication link shall be established. 4.2.6 Arrangements for testing repeaters For the immunity tests of repeaters, the wanted RF input signal shall be coupled to one antenna port at a level which will result, when measured, in the maximum rated RF output power per channel, as declared by the manufacturer. The test shall either be repeated with a wanted signal coupled to the other antenna port, or a single test shall be performed with the specified input signals being simultaneously coupled to both antenna ports. 4.3 Exclusion band of radio communications equipment The provisions of EN 301 489-1 [1], clause 4.3 shall apply. 4.3.1 Base station receiver exclusion band The BSS receiver exclusion band is the band of frequencies over which no tests of radiated immunity of a receiver are made. The lower frequency of the exclusion band is the lower frequency of the BSS receive band of the EUT minus 6 %. The upper frequency of the exclusion band is the upper frequency of the BSS receive band of the EUT plus 5 %. SIST EN 301 489-8 V1.2.1:2003
ETSI ETSI EN 301 489-8 V1.2.1 (2002-08) 10 4.3.2 Base station transmitter exclusion band The BSS transmitter exclusion band is the band of frequencies over which no tests of radiated immunity of a transmitter are made. The exclusion band for transmitters extends ±200 kHz from the carrier frequency of each activated transmitter. 4.3.3 Repeater and ancillary RF amplifier exclusion band The exclusion band for repeaters and ancillary RF amplifiers is the band of frequencies over which no tests of radiated immunity of the EUT are made. The exclusion band for a repeater or ancillary RF amplifier is the range (or ranges) of frequencies for which at least one of the following conditions are met: - the gain (measured in either direction between two RF ports) is greater than 25 dB; - the gain (measured in either direction between two RF ports) is no more than 25 dB below the gain measured at the centre of a manufacturers declared operating band. A range of frequencies is only considered to be an operating band if the measured gain at the centre of this band is greater than 0 dB. 4.4 Narrowband responses of receivers Responses on receivers or duplex transceivers occurring during the test at discrete frequencies which are narrow band responses (spurious responses), are identified by the following method: - if during an immunity test the RXQUAL or BER being monitored goes outside the specified limit, it is necessary to establish whether the RXQUAL or BER increase is due to a narrow band response or to a wideband phenomenon. Therefore, the test shall be repeated with the unwanted signal frequency increased, and then decreased by 400 kHz; - if the RXQUAL or BER meets the conformance requirement in either or both of the above 400 kHz offset cases, then the response is considered as a narrow band response; - if the RXQUAL or BER continues not to meet the conformance requirement, this may be due to the fact that the offset has made the frequency of the unwanted signal correspond to the frequency of another narrow band response. Under these circumstances the procedure is repeated with the increase and decrease of the frequency of the unwanted signal set to 500 kHz; - if the RXQUAL or BER still continues not to meet the conformance requirement with the increased and/or decreased frequency, the phenomenon is considered wideband and the equipment therefore fails the test. Narrow band responses are disregarded. 4.5 Normal test modulation The normal test modulation shall be delivered by a suitable mobile station or base station system test equipment (BSSTE) (hereafter called "the test system").
