Pulse techniques and apparatus - Part 2: Pulse measurement and analysis, general considerations
Gives the definitions and descriptions of the techniques and procedures for time domain pulse measurements. The definitions and descriptions are independent of specific devices, apparatus, instruments or computing devices which may be used in pulse measurements.
Cores for inductors and transformers for telecommunications - Part 1: Measuring methods
Applies to magnetic cores, mainly made of magnetic oxides or metallic powders, used in inductors and transformers for telecommunication equipment and electronic devices employing similar techniques. Gives guidance for the drafting of those parts of specifications for magnetic cores that are concerned with measuring methods for magnetic and electric core properties.
1. Scope
1.1 Before an attempt can be made to measure or gauge the requirements specified on engineering drawings or specifications, to ascertain whether an actual size or value meets the specified limits, it is essential to establish a precise interpretation of the limiting values, and the standard conditions under which they shall be measured. It is the intent of this standard to provide…
Radio-frequency cables - Part 0: Guide to the design of detailed specifications
Lays down requirements for flexible or semi-flexible radio-frequency cables of coaxial or twin conductor types designed for use in radiocommunication equipment and in electronic devices employing similar techniques. The dielectric may be of the solid, air-spaced, or semi-airspaced types, consisting of a thermoplastic of low-loss polymeric resin or of a thermosetting compound, or of a mineral…
