13 FOREWORD
14 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
15 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
16 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
17 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
18 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
19 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
20 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
21 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
22 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
23 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
24 consensus of opinion on the relevant subjects since each technical committee has representation from all
25 interested IEC National Committees.
26 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
27 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
28 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
29 misinterpretation by any end user.
30 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
31 transparently to the maximum extent possible in their national and regional publications. Any divergence between
32 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
33 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
34 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
35 services carried out by independent certification bodies.
36 6) All users should ensure that they have the latest edition of this publication.
37 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
38 members of its technical committees and IEC National Committees for any personal injury, property damage or
39 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
40 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
41 Publications.
42 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
43 indispensable for the correct application of this publication.
44 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
45 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
46 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
47 may be required to implement this document. However, implementers are cautioned that this may not represent
48 the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
49 shall not be held responsible for identifying any or all such patent rights.

71 Proposed revision of CISPR 16-1-1 on specifications for receivers
72 in the frequency range 18 GHz to 40 GHz.
73 This CDV was prepared by CISPR/A AHG7 and is based on the comments received on the
74 second committee draft (see CISPR/A/1410/CD and CISPR/A/1434/CC) and decisions taken
rd
75 during the AHG7 meeting on 23 of October 2024. The proposed changes are marked in red.
76 In addition, correction is included of a clear error in a Clause 3 note-to-entry Bibliography cross-
77 reference, as found during CISPR/A Editing Committee review of the draft CDV. Specifically,
78 the Biblio. reference for Formula (4), in Note 1 to entry of 3.6 impulse bandwidth, is corrected
79 from [12] CISPR 16-2 series, to [9] Keller and Feser (in accordance with the associated
80 originating documents CIS/A/1247/CC and CIS/A/1215A/CD). Other editorial changes across
81 the entire Ed 5.0 are deferred for consideration during future maintenance work.
82 Two projects in the present CISPR/A work programme cover Amendment 1 to Ed. 5.0 of CISPR

Since the response of a peak measuring receiver to non-overlapping pulses is proportional to its impulse
bandwidth, either the actual bandwidth is quoted in the result or the level may be quoted as "in a 1 MHz
bandwidth,", calculated by dividing the measured value by the impulse bandwidth in MHz (see 3.6). For other
types of broadband disturbance, this procedure can introduce an error. Therefore, data measured with th
