This application note introduces free space light measurement jigs for measuring the emission spectrum of a light source that propagates in free space or the optical transmission spectrum of an optical filter. It describes four types of jigs for light sources and one type for filters.
To accurately measure pulsed light using an optical spectrum analyzer (OSA), it is necessary to understand the characteristics of the OSA and select the appropriate measurement method and settings.

入门指南
This video demonstrates side mode suppression ratio (SMSR) analysis using an AQ6370E OSA and explains how to adjust the signal span to capture side modes and execute SMSR analysis to detect and locate the closest peaks from a 1310 nanometer laser via a connected light source module. SMSR analysis allows engineers to quickly identify and quantify the differences between the main peak and any side peaks in terms of nanometers and power which helps ensure the quality and accuracy of a laser's output. Manufacturers want to see a single, clean peak in a laser's output without side modes or additional peaks, to indicate a laser is performing as expected.
The AQ7933 OTDR Emulation Software is software that can re-analyze and create reports of trace data measured on a Yokogawa OTDR.
It is more intuitive than conventional software and has a wealth of useful features including event map and pass / fail judgment screen.
This video will introduce the basic usage of the AQ7933 such as one-way analysis, two-way (bidirectional) analysis, and report creation.
