Optical test bay for testing fascia display device of aircraft, has optical emission source to emit video stream, and calibration table to determine optical power emitted towards electronic equipment for attenuation value

摘要

The bay (300) has an optical emission source to emit a predetermined video stream, and a programmable optical attenuator (331) including an input port connected to the source and an output port. An optical switch (332) includes an input port connected to the output port of the attenuator and an output port connected with an electronic equipment to be tested. A calibration table is provided to determine optical power emitted towards the electronic equipment for a programmed attenuation value, based on power emitted by the source and attenuations of optical components.
