8 Setting Up the Instrument in
Spectral Transmittance Mode
Before performing a spectral analysis in the Spectral Transmittance mode,
you must set up your OSA module and the test application with the
appropriate parameters, as explained in this chapter.
Select the Spectral Transmittance test mode as explained in Selecting a
Test Mode on page 18 before setting up the test parameters.
³
The preferences are the result displayed in the graph and tables, as
well as the job information and related comments saved with each file
(See Defining Preferences on page 184 for more details).
³
The analysis parameters include the channel list details, pass-fail
threshold settings and allows you to select the noise and power
calculation methods (See Setting Up Spectral Transmittance Analysis
Parameters on page 198 for more details).
³
The acquisition parameters include the type of measurement you want
to perform and the wavelength range (See Setting Up Acquisition
Parameters on page 205 for more details).
The preferred way to set up your unit is to use the complete analysis setup
parameters and complete the information in all tables, as explained in
Setting Up Spectral Transmittance Analysis Parameters on page 198. This
setup will be used for the next acquisition.
