High-voltage switchgear and controlgear - Part 37-082: Standard practice for the measurement of soun...
IEC/IEEE 62271-37-082:2012(E) provides methods for the measurement of sound pressure level produced by outdoor alternating current circuit-breakers in a free-field environment. These methods may also be used indoors or in restricted field, provided that precautions are observed in the measurement and interpretation of the results. This standard has been prepared by subcommittee 17A: High-voltage…
Fibre optic communication subsystem test procedures - Part 2-2: Digital systems - Optical eye patter...
IEC 61280-2-2:2012 describes a test procedure to verify compliance with a predetermined waveform mask and to measure the eye pattern and waveform parameters such as rise time, fall time, modulation amplitude and extinction ratio. This fourth edition cancels and replaces the third edition published in 2008 and constitutes a technical revision .This edition includes the following significant…
