Introduction

This specification is based on JJF 1071-2010 "Rules for the preparation of national metrological calibration specifications", JJF 1059.1-2012 The requirements in the Measurement and Expression of Uncertainty are written. Compared with JJF 1237-2010 SDH/PDH Transmission Analyzer Calibration Specification, in addition to editorial modifications, this The main technical changes in the specification are as follows. --- Added introduction; --- Removed YD/T 620-1998, YD/T 966-1998 and four ITU-T recommendations (G.691, G.957, O.151, O.162) A total of six reference documents, adding YD/T 2273-2011, ITU-T recommendations O.150 (05/1996) two references; --- Added measurement performance requirements for STM-256, modified the measurement standards related to STM-256 and Metering performance of other equipment; --- Delete the table of some optical interface indicators, and instead provide only typical values or ranges; --- Remove the measurement performance requirements of the optical interface receiver overload power and the corresponding calibration method; --- Separately regulate the functional requirements of the test pattern generation and reception, and separately describe the inspection method; --- For some functional requirements, the terms of the document are no longer quoted, and the specific requirements are directly given; --- Modified the calibration result measurement uncertainty evaluation example. The release of previous versions of this specification is. ---JJF 1237-2010. SDH/PDH Transmission Analyzer Calibration Specifications
