1.1.1 This standard applies to general-purpose cathode-ray oscilloscopes (hereinafter called "oscilloscopes") for measuring electrical quantities, containing at least:
— a cathode-ray tube,
— a vertical deflection device,
— a time base and/or a horizontal deflection device.
1.1.2 This standard is also applicable to:
— multitrace oscilloscopes (Sub-clause 2.1.4) when they comply with Sub-clause 1.1.1,
— complete assemblies of oscilloscopes with detachable or incorporated parts, e.g. probes or interchangeable plug-in units.
1.1.3 This standard applies also to oscilloscopes for measuring non-electrical quantities, when it is possible to express their performance in terms of an electrical quantity which represents the non-electrical quantity.
1.1.4 This standard is concerned with the qualities of the cathode-ray tubes only when these are necessary for the evaluation of oscilloscopes. The intrinsic qualities of cathode-ray tubes will be dealt with in another standard.
1.1.5 Some portions of this standard may be applicable, by special agreement between manufacturer and user, to observation or special-purpose oscilloscopes, e.g.:
— sampling oscilloscopes,
— characteristic curve tracers,
— vectorscopes;
— radial deflection oscilloscopes,
— storage oscilloscopes.
1.1.6 Safety requirements are not dealt with in this standard. Unless otherwise agreed upon, devices such as those in Clause 1 shall comply with IEC Publication 348, Safety Requirements for Electronic Measuring Apparatus.
