scope:

This standard applies to equivalent-time sampling oscilloscopes for measuring electrical quantities. This standard is also applicable to: multi-trace sampling oscilloscopes when they comply with Sub-clause 1.1; complete assemblies comprising sampling oscilloscopes with detachable or incorporated parts, e.g. probes or interchangeable plug-in units. 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. 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. Some portions of this standard may be applicable, by special agreement between manufacturer and user, to the other types of sampling oscilloscopes; for instance, real-time sampling oscilloscopes or those using digital displays or programmable units.
