Analysis Tab Page
The SWS software provides flexible analysis capabilities. The Analysis tab page is used to
specify the ITU or other channels and the types of analyses to be performed on them. The
results of the analyses are presented in tabular form, with each row corresponding to a physical
channel on the receiver.
Each column is reserved for a particular parameter that is analyzed. The parameters that can be
calculated and presented are:
•
Center wavelength
•
Bandwidth
•
Passband
•
Crosstalk
•
Flatness
•
Maximum and minimum peaks
The parameters can be measured in specified wavelength channels, either ITU or user-defined.
For some parameters, the threshold, or power level at which they are calculated, can be set by
the user. Threshold is required for bandwidth, center wavelength, and passband calculations.
The Analysis area is at the bottom left of the main window, shown in Figure 71, and appears as a
read-only spreadsheet. The software performs basic analysis on the data being viewed in the
