84 – Operating and Maintenance Instructions
CITUStartWavelength, CITUStopWavelength, CITUSize, <CITUListBegin>, and <CITUListEnd>
are parameters required for crosstalk calculation. Click the Setup button for ITU channels.
Analysis definition files can be set up once, for any number of channels, and reused on any
receiver, without regard to channels selected. The analysis is performed for only the channels
that exist.
Basic analysis includes finding the minimum and maximum insertion losses, finding bandwidth
and center wavelength, turning markers on or off, and finding peaks. The analysis can be
performed in a selected wavelength or frequency range.
The advanced analysis section allows the user to add a comment to the analysis, provides
selections to compute passband, flatness, crosstalk, and cumulative crosstalk, and sets up ITU
channels used in the analysis.
The analysis definition file must be saved, or an old analysis definition file loaded, before analysis
can be performed.
Setting the Analysis Parameters
Before conducting analysis on the data, the analysis parameters in the Analysis Setup dialog box
must be defined. Open the Analysis Setup Dialog Box by clicking the Select Analysis button on
the Analysis tab page. This dialog box is shown in Figure 60.
