14、“Expression of the performance of pulse generators” published in1978 by the International Electrotechnical Commission (IEC). This British Standard is published under the direction of the Electronic Equipment Standards Committee. The preface is an extract from the preface of IEC Publication624 and ha
15、s been included because it contains information relevant to the main text. Terminology and conventions. The text of the International Standard has been approved as suitable for publication, without deviation, as a British Standard. Some terminology and certain conventions are not identical with thos
16、e used in British Standards. Additional information. The last sentence of9.2.10, whilst being a correct statement, is not as informative as it might be and, whilst in the simplest mode, the two pulses may be nominally identical, the user of the standard should bear in mind that in other cases the ou
17、tputs may be controlled independently as to pulse duration, amplitude, first and last transition durations, etc. The definitions in6.5.3 and6.6.2 b) are understood to be likely to require amendment after publication of Chapter301 of the International Electrotechnical Vocabulary (I.E.V.). Attention i
18、s drawn to the fact that some of the definitions adopted for the purposes of this standard in section2 differ significantly from definitions in BS5233:1975 “Glossary of terms used in metrology”. A British Standard does not purport to include all the necessary provisions of a contract. Users of Briti
19、sh Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

22、ver.iv blankBS5813:1979 BSI 01-2000 1 Preface At first reading, this standard may appear to differ significantly from previous IEC publications on electronic measuring equipment. This is not the case; the differences are superficial and stem from the wide diversity in form, functional capability, an
23、d means for control which are found in pulse generators. The object of this preface is to state the following assumptions: The standard is intended to be used by a pulse generator manufacturer who, to conform, must make a complete statement of performance. A user, depending on his point of view or s
24、alient interests, may wish to verify performance to varying degrees, ranging from one performance characteristic to a verification that is as complete as the manufacturers. The manufacturer has read and is familiar with the entire standard. Finally, the manufacturer has a new pulse generator which h
25、e wishes to characterize in accordance with this standard. He wishes to proceed in an efficient manner which will ensure clarity and completeness. Table I in Section5 is, in effect, a plan or guide for the handling of each performance characteristic and it may be helpful to refer toTable I for the s
26、equence of operations given below. Bearing in mind that the following is merely an example, subject to many variations, the manufacturer would carry out the following steps: 1) Make a list of all performance characteristics which are found in the pulse generator. Here, reference to Section3 (which l
27、ists categories of performance characteristics) may be helpful, bearing in mind that the categories listed in Section3 are merely representative and are not exhaustive. 2) Next to each performance characteristic in the list from Item1) above, list the type of control which is provided for that perfo
28、rmance characteristic (types of control are listed in the left-hand column ofTable I and are specified in Section4). 3) Repeat Item2) above, for each performance characteristic which is subject to multiple control (seeClause19). 4) Repeat Item2) and possibly Item3) above, for each performance charac
29、teristic which is subject to dual control (seeClause20). NOTEAt this point, all pairings of performance characteristics with types of control will have been exhaustively listed. 5) To each pairing of performance characteristic with type of control in the list, add the type(s) of error(s) which will
30、be specified for each pairing (types of error are listed in the top row ofTable I and are defined in Section2). NOTEAt this point, each performance characteristic is grouped with at least one type of control and at least one type of error to be specified. Multiple combinations involving one performa
31、nce characteristic and different types of control and/or different types of error may also exist. In any event, each such grouping, at least conceptually, is dealt with separately. 6) For each grouping of performance characteristic with type of control and type of error: a) the nature of the specifi
32、cation which shall be made will be found inSection5; b) the applicable general test conditions will be found inSection6; and c) the applicable specific test conditions will be found inSection6; all at the sub-clauses listed inTable I. Nothing in the above shall be construed to modify the requirement
33、s of the standard itself and, useful though it is,Table I should be used only as a guide. The user should bear in mind: a) that the sequence described above applies also to accessories and modular pulse generators (Sub-clauses5.2 and5.3); b) the pulse generator nomenclature defined inClause9; and c)
34、 the requirements for the specification of dual-controlled quantities inClause27. Section 1. General 1 Scope This standard applies to the specification of pulse generators and to accessories used with generators. Specifically excluded from the scope of this standard are generators with continuous or
35、 pulsed sinusoidal outputs, television pattern generators, complex function generators, and generators for insulation resistance testing. 2 Object Within its scope, this standard establishes: 1) the definitions related to generators; 2) the terminology for describing the functional performance of ge
36、nerators; 3) a listing of performance characteristics on which a statement of the performance of generators may be based; 4) the criteria for evaluating the performance of generators; andBS5813:1979 2 BSI 01-2000 5) the tests necessary to verify the performance of generators. Section 2. Definitions
37、For the purpose of this standard, the following definitions apply: 3 Definition of pulse terms The pulse terms used throughout this standard are defined in IEC Publication469-1, Pulse Techniques and Apparatus, Part1; Pulse Terms and Definitions. 4 Pulse measurement and analysis Definitions of pulse
38、measurement terms used and descriptions of pulse measurement techniques referred to in this standard are provided in IECPublication469-2, Part2; Pulse Measurement and Analysis, General Considerations. 5 Pulse generator terms 5.1 Pulse generator An apparatus which supplies electrical energy in pulse
39、form at an accessible output. NOTEThroughout this standard “generator” is used in place of “pulse generator”. 5.2 Generator accessory A device or apparatus which is or may be a part of a generator, associated with a generator, or associated with another generator accessory to modify or establish in
40、a specified manner one or more characteristics of a generator. Throughout the remainder of this standard “generator accessory” is included in “generator”. 5.2.1 Permanent (non-permanent) generator accessory A generator accessory which is permanently (occasionally) associated with a generator and whi
41、ch is (is not) essential to its operation. 5.2.2 Interchangeable generator accessory A non-permanent generator accessory which has its own properties which are independent of any generator with which it may be associated. 5.2.3 Partially interchangeable generator accessory An interchangeable generat
42、or accessory which may be associated with a limited and specified set of generators or generator accessories. 5.2.4 Non-interchangeable generator accessory A generator accessory which is associated with one particular generator. A non-interchangeable generator accessory and the generator with which
43、it is associated have mutually interacting adjustments or characteristics. When such mutual interaction exists, this standard applies to the combination of the generator and the non-interchangeable generator accessory. 5.3 Modular generator A generator which is a combination of two or more generator
44、 accessories. 5.3.1 Generator main frame A partially interchangeable generator accessory which provides common services and/or facilities (e.g.mechanical mounting, a.c.and/or d.c.power, analogue and/or digital signal paths, cooling, etc.) for itself and for one or more associated generator accessori
45、es. Typically, in the absence of other generator accessories, a generator main frame cannot function as a generator. 5.3.2 Generator plug-in unit A partially interchangeable generator accessory which, typically: 1) may be associated with one or more specified generator main frames; 2) is adapted by
46、plug and socket connections and its construction to use the services and/or facilities provided by the associated generator main frame; and 3) performs specified generator functions. In the absence of a generator main frame, a generator plug-in unit cannot function as a generator. 6 Terms related to
47、 the performance of generators 6.1 Performance The degree to which the intended functions of a generator are accomplished. 6.2 Performance characteristic One of the quantities assigned to a generator in order to define by values, tolerances, ranges, etc.,the performance of the generator. NOTEThe ter
48、m “performance characteristic” does not include influence quantities (see note ofSub-clause6.3). 6.3 Influence quantity Any quantity, generally external to a generator, which may affect the performance of the generator. NOTEWhere a change of a performance characteristic affects another performance c
49、haracteristic, it is referred to as an influencing characteristic (seeSub-clauses6.4 and8.3).BS5813:1979 BSI 01-2000 3 6.4 Influencing characteristic A performance characteristic which, when altered in value or state, produces a change in the value or state of one or more other performance characteristics (influenced characteristics). 6.5 Terms related to values and ranges 6.5.1 Rated value The value (or one of the values) of a quantity to be measured, observed, supplied or set, which the manufacturer has assigned to the apparatus (I.E.V.151-04-03). 6.5.2 Rated ran
