8、tem (RDS) reception, published by the European Committee for Electrotechnical Standardization (CENELEC). It is identical with IEC 315-9:1996, published by the International Electrotechnical Commission (IEC), and forms Part 9 of a multi-Part standard on measurement methods on radio receivers. Some Pa
9、rts of this standard appear under the number BS 4054, of the same generic title. This Part specifies the conditions, characteristics and measurement methods of determining the overall RDS reception characteristics of a sound broadcasting receiver to facilitate comparison of measurements made using v

27、s of measurements made by different observers. Performance requirements (limit values for the characteristics required for acceptable RDS performance) are not specified. The methods of measurement are conceived for determining the overall performance of the receiver, without attempting to study its
28、functional units separately. 1.2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IEC 315. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to
29、agreements based on this part of IEC 315 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. IEC 315-1:1988, Methods of measurement on radio receiver

IEC 315-4:1982, Methods of measurement on radio receivers for various classes of emission Part 4: Radio-frequency measurements on receivers for frequency modulated sou

This avoids the need f
32、or cross-references when reading the text. For the purposes of this part of IEC 315, the following definition applies: 1.3.1 satisfactory reception the correct display of the programme service name (PS) within 10 s after the beginning of the relevant step of a test NOTE 1Any eight characters from th
33、e available character set may be chosen as the programme service name. The chosen name(s) should be stated with the results. NOTE 2The correct display of the programme service name is used as the criterion for satisfactory reception, because this application is generally available on RDS receivers,
34、and can be used without making internal connections to the receiver circuits. NOTE 3If the PS is not available (on a special purpose receiver, for example), another, stated, criterion may be used. In this case, it may be necessary to make internal connections to the receiver in order to obtain a sui
35、table output signal for measurement. If possible, a correlation should be established between this criterion and the PS criterion, and stated with the results. 2 General notes on measurements 2.1 Preliminary measurements As the results of various measurements described in this part may be influenced
36、 by other properties of the receiver, the related measurements given in IEC 315-1 and IEC 315-4 should be carried out first. 2.2 Standard signals Unless otherwise specified, the following standard signals shall be used for the measurements: 2.2.1 Standard measuring signal 2.2.2 Standard measuring si
37、gnal with ARI (see note 2) When it is required to carry out measurements in the presence of an ARI signal, the following requirements apply, in addition to those in 2.2.1. Standard radio-frequency (r.f.) input signal level:70 dB(fW) Standard carrier frequency: 69 MHz, 83 MHz or 98 MHz, (depending on
38、 the tuning range of the receiver, see IEC 315-4, Table 1) Stereophonic signal without audio modulation Frequency deviation of 19 kHz pilot tone: or in accordance with the broadcasting system standards for which the receiver is designed 6,75 kHz Frequency deviation of RDS signal: 1,20 kHz Phase rela
39、tion to the third harmonic of the pilot tone:0 1 Repetition rate for RDS group type 0A:approximately 4/s Licensed Copy: sheffieldun sheffieldun, na, Sat Nov 11 09:38:42 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 60315-9:1996 4 BSI 11-1998 NOTE 1Unless otherwise stated, the receiver is tuned to th
40、e standard measuring frequency nearest the centre of the broadcast band for which the receiver is designed (see IEC 315-4, Table 1). NOTE 2ARI is the Autofahrer-Rundfunk-lnformation (broadcast information for motorists), a traffic information system used in some countries, and which can be broadcast
41、 simultaneously with the RDS system from the same transmitters. 2.3 RDS data conditions The RDS data shall consist of an appropriate PI code, a PS name, two AF values and default values (see annex B, references 1 and 2) for TP, DI, TA, PTY and M/S, with a maximum repetition rate for group type 0A of
42、 four groups per second. 2.4 Standard conditions for measurements These shall be taken from IEC 315-1 and IEC 315-4. If the receiver has a “regionalization mode”, this shall be switched off. Except where stated, the alternative frequency (AF) mode shall be switched off. 3 Characteristics and methods
43、 of measurement 3.1 RDS sensitivity 3.1.1 Characteristic to be specified The lowest radio-frequency input signal level for which satisfactory reception (see 1.3.1) is obtained. 3.1.2 Method of measurement a) The receiver and the signal source are operated under standard measuring conditions, accordi
44、ng to 2.2, and the correct display of the programme service name is checked. b) The radio-frequency input signal is switched off, and a new programme service name is set into the RDS encoder. The new programme service name shall differ from the previous one in all eight characters. c) The radio-freq
45、uency input level is then reduced to a lower value, for which a correct display is not expected, and then switched on again. d) If satisfactory reception with the new programme service name is not achieved, the whole sequence is repeated from step b), using a higher radio-frequency input level in st
46、ep c). NOTEIt is necessary to repeat all the steps, because the receiver may have stored parts of the second programme service name correctly at the low input signal level. e) This process is repeated up to the radio-frequency input signal level at which satisfactory reception is achieved, and this
47、level is noted. f) If required, the measurement may be repeated with an ARI signal present, using the standard signal specified in 2.2.2. 3.1.3 Presentation of results The lowest radio-frequency input signal level(s) determined according to steps e) and f) of 3.1.2 shall be stated as RDS sensitiviti
48、es, in dB(fW). 3.2 RDS deviation sensitivity 3.2.1 Characteristic to be specified The lowest value of deviation of the main carrier of the radio-frequency input signal by the RDS subcarrier for which satisfactory reception is achieved. 3.2.2 Method of measurement a) The receiver and the signal sourc
49、e are operated under standard measuring conditions according to 2.2, and the correct display of the programme service name is checked. b) The radio-frequency input signal is switched off, and a new programme service name is set into the RDS encoder. The new programme service name shall differ from the previous one in all eight characters. c) The RDS frequency deviation is then reduced below the standard value and the radio-frequency input signal is switched on again. d) If satisfactory reception is achieved, the mea
