This document introduces the passive component testing mode of EXFO OSA20 optical spectrum analyzer, including how to launch the mode, set scan parameters and analysis settings, etc.
This guide explains how to use the OSA20’s Passive Component Testing (PCT) mode to measure insertion loss in optical components. It covers launching the mode, setting scan parameters, acquiring reference and device-under-test signals, and calculating the transfer function. The guide includes setup diagrams and analysis results display instructions.
The PCT mode is designed for lab and manufacturing environments to characterize passive components like filters. It requires defining scan settings and analysis parameters before testing. Results are displayed as a transfer function graph with metrics like ripple, roll-off, and transition band.
The OSA20’s PCT mode tests passive components.
A broadband source and the device under test (DUT) connected to the setup.
Acquire the reference trace from the broadband source.
The transfer function is displayed in the chart under the plot.
