INTERNATIONAL ELECTROTECHNICAL COMMISSION
EXPRESSION OF THE PERFORMANCE
OF PULSE GENERATORS
FOREWORD
The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on which all the
1)
National Committees having a special interest therein are represented, express, as nearly as possible, an international
consensus of opinion on the subjects dealt with.
They have the form of recommendations for international use and they are accepted by the National Committees in that
2)
sense.
In order to promote international unification, the IEC expresses the wish that all National Committees should adopt the
3)
text of the IEC recommendation for their national rules in so far as national conditions will permit. Any divergence between
the IEC recommendation and the corresponding national rules should, as far as possible, be clearly indicated in the latter.
PREFACE
This standard has been prepared by Sub-Committee 66A, Generators, of I E C Technical Commit-
tee No. 66, Electronic Measuring Equipment.
A first draft was discussed at the meeting held in The Hague in 1973. As a result of this meeting, a
draft, Document 66A(Central Office)28, was submitted to the National Committees for approval
under the Six Months' Rule in September 1975.
The following countries voted explicitly in favour of publication:
Netherlands
Belgium
Denmark Poland
Spain
Finland
Sweden
France
Switzerland
Germany
Union of Soviet
Hungary
Socialist Republics
Italy
United Kingdom
Japan
United States of America

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, and means for control which are found in pulse gen-
erators.
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 salient interests,
may wish to verify performance to varying degrees, ranging from one performance characteristic to
a verification that is as complete as the manufacturer's.
The manufacturer has read and is familiar with the entire standard.
–
Finally, the manufacturer has a new pulse generator which he 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 Section Five is, in effect, a plan or guide for the handling of each performance character-
istic and it may be helpful to refer to Table I for the sequence 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 Section Three (which lists categories of performance characteristics) may be helpful,
bearing in mind that the categories listed in Section Three are merely representative and are not
exhaustive.
2) Next to each performance characteristic in the list from Item 1) above, list the type of control
which is provided for that performance characteristic (types of control are listed in the left-hand
column of Table I and are specified in Section Four).
Repeat Item 2) above, for each performance characteristic which is subject to multiple control (see
3)
Clause 19).
4) Repeat Item 2) and possibly Item 3) above, for each performance characteristic which is subject to
dual control (see Clause 20).
—At this point, all pairings of performance characteristics with types of control will have been exhaustively listed.
Note.
To each pairing of performance characteristic with type of control in the list, add the type(s) of
5)
error(s) which will be specified for each pairing (types of error are listed in the top row of Table I
and are defined in Section Two).
Note. —At 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 performance 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.
For each grouping of performance characteristic with type of control and type of error:
6)
the nature of the specification which shall be made will be found in Section Five;
a)
b) the applicable general test conditions will be found in Section Six; and
the applicable specific test conditions will be found in Section Seven;
c)
all at the sub-clauses listed in Table I.
Nothing in the above shall be construed to modify the requirements of the standard itself and,
useful though it is, Table I should be used only as a guide. The user should bear in mind:
that the sequence described above applies also to accessories and modular pulse generators (Sub-
a)
clauses 5.2 and 5.3);
b) the pulse generator nomenclature defined in Clause 9; and
c) the requirements for the specification of dual-controlled quantities in Clause 27.

EXPRESSION OF THE PERFORMANCE
OF PULSE GENERATORS
SECTION ONE – 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 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 generators;
3) a listing of performance characteristics on which a statement of the performance of genera-
tors may be based;
4) the criteria for evaluating the performance of generators; and
5) the tests necessary to verify the performance of generators.
SECTION TWO – DEFINITIONS
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 Pub
lication 469-1, Pulse
Techniques and Apparatus, Part 1; Pulse Terms and Definitions.
4. Pulse measurement and analysis
Definitions of pulse measurement terms used and desc riptions of pulse measurement tech-
niques referred to in this standard are provided in IEC Pub lication 469-2, Part 2; Pulse
Measurement and Analysis, General Considerations.

Pulse generator terms
5.
Pulse generator
5.1
An apparatus which supplies electrical energy in pulse form at an accessible output.
—Throughout this standard "generator" is used in place of "pulse generator".
Note.
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 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
which 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.
Partially interchangeable generator accessory
5.2.3
An interchangeable generator accessory which may be associated with a limited and specified
set of generators or generator accessories.
Non-interchangeable generator accessory
5.2.4
A generator accessory which is associated with one particular generator. A non-interchange-
able generator accessory and the generator with which 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 accessories.
Generator main frame
5.3.1
A partially interchangeable generator accessory which provides common services and/or facil-
ities (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 accessories. Typically, in the
absence of other generator accessories, a generator main frame cannot function as a generator.

– 15 –
5.3.2 Generator plug-in unit
A partially interch an
geable generator accessory which, typically:
1)
may be associated with one or more specified generator main frames;
2)
is adapted by 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 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.
Note. –The term "performance characteristic" does not include influence quantities (see note of Sub-clause 6.3).
6.3 Influence quantity
Any quantity, generally external to a generator, which may affect the performance of the
generator.
Note. –Where a change of a performance characteristic affects another performance characteristic, it is referred to as an
influencing characteristic (see Sub-clauses 6.4 and 8.3).
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 range
The range of a quantity to be me
