Managing Spectral Transmittance Test Results
Managing Spectral Transmittance Test Results
The application allows you to view and manage your spectral
transmittance test results. You can view the graph of your acquisition,
results for a single channel, global results and information about the trace.
ST Graph Tab
The ST Graph tab allows you to view the spectrum of the input trace, the
output trace and the calculated ST trace. This graph represents the optical
power against wavelength. When there is no acquisition, the graph zone
shows a procedure explaining how to take measurements with the OSA
application.
