IEC 62129-1:2016 specifies procedures for calibrating an optical spectrum analyzer that is developed for use in fibre-optic communications and designed to measure the power distribution of an optical spectrum. It does not apply to an optical wavelength meter that measures only centre wavelengths, a Fabry-Perot interferometer or a monochromator that has no display unit. This first edition of IEC 62129-1 cancels and replaces the first edition of IEC 62129, published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - update of term and definitions; - update of calibration conditions; - calculation change of uncertainties related to wavelength temperature dependence, power linearity, power level temperature dependence; - move of Annex E to the bibliography. Keywords: calibrating an optical spectrum analyser

This international standard is applicable to instruments measuring radiant power emitted from sources which are typical for the fibre-optic communications industry. These sources include laser diodes, light emitting diodes (LEDs) and fibre-type sources. The radiation may be divergent or collimated. The standard describes the calibration of power meters to be performed by calibration laboratories or by power meter manufacturers.

This International Standard specifies methods of measurement for the power consumption of television sets, video recording equipment, Set Top Boxes (STBs), audio equipment and multi-function equipment for consumer use. Television sets include, but are not limited to, those with CRT, LCD, PDP or projection technologies. Moreover the different modes of operation which are relevant for measuring power consumption are defined. The methods of measurement are only applicable for equipment which can be connected to the mains. The measuring conditions in this standard represent the normal use of the equipment and may differ from specific conditions, for example as specified in safety standards.

In the following Appendix I a brief description of a test signal is given, stating its particular advantages for measurement of amplitude and phase simultaneously. It was formerly published as Supplement 3.7 in the Blue Book (1988), Fascicle IV.4, and then renumbered on 26 June 1998 as Appendix I to ITU-T O.81 without further modification.
