IEEE 181-1977 pdf free.IEEE Standard on Pulse Measurement and Analysis by Objective Techniques.
1.1 Scope.This standard provides definitionsand descriptions of the techniques and procedures for time domain pulse measurements.The definitions and descriptions provided areindependent of specific devices, apparatus, in-struments.or computing devices which maybe used in pulse measurements and are prerequisite to:
(1)Efficient communication of the resultsof pulse measurements
(2) Standards for pulse apparatus
(3)Standards for apparatus which employspulse techniques.
1.2 Object.Within its scope,the object of thisstandard is the definition of terms and the description of techniques and procedures whichare applicable:
(1)To the determination of the character-istics of practical and hypothetical pulses(2)Regardless of accuracy or precision
(3)To a wide range of technologies and dis-ciplines.
For the definitions of general pulse termsused in this standard reference should bemade to IEEE Std 194-1977,IEEE StandardPulse Terms and Definitions. Throughoutthis standard. where required, specific sec-tions of IEEE Standard 194-1977 are referenced.
2.1 Pulse Measurement Terms. The pulsemeasurement terms defined in this section areapplicable to measurement in general and arenot defined in order to draw a distinction between pulse measurement and measurementin general.
For the purposes of this standard, the following definitions shall apply.
2.1.1 Pulse Measurement. The assignmentof a number and a unit of measurement to acharacteristic, property, or attribute of a pulse wherein the number and unit assigned indicate the magnitude of the characteristicwhich is associated with the pulse. Typically,this assignment is accomplished by comparison of a transform of the pulse，its pulsewaveform，with a scale or reference which iscalibrated in the unit of measurement.
2.1.2 Method of Pulse Measurement. Amethod of making.a pulse measurement com-prises:
(1)The complete specification of the func-tional characteristics of the devices，ap-paratus，instruments，and auxiliary equip-ment to be used
(2)The essential adjustments required
(3)The procedures to be used in making essential adjustments
(4)The operations to be performed andtheir sequence
(5)The corrections that will ordinarilyneed to be made
(6)The procedures for making such correc-tions
(7)The conditions under which all oper-ations are to be carried out.
2.1.3 Pulse Measurement Process. A real-ization of a method of pulse measurement ‘ interms of specific devices，apparatus，instruments, auxiliary equipment,conditions. oper-ators, and observers.
2.1.4 State of Statistical Control. In a pulsemeasurement process, that state wherein a de-gree of consistency among repeated measurements of a characteristic. property, or attribute is attained.IEEE 181 pdf download.
