Introducing the OSA20

The OSA20 is a diffraction-grating based optical spectrum analyzer, using a touch sensitive
display with multi-touch gesture control. It provides an extensive suite of built-in analysis
functions enabling input signal measurement and analysis for many common applications.
A wide range of communication ports allows remote control operations and export of data.
The OSA20 features one general analysis mode and seven application-oriented modes.
Each analysis mode has a full suite of analysis functions for a detailed spectrum analysis.
