How to Perform SMSR Analysis of a Laser's Output with an OSA

관리자 2026-03-16 조회수 100

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.
