The second graph provides a more detailed visualisation of the basebands and the spectral windows for each for the basebands. The functionality of the display is very similar to the Receiver and LO visualisation discussed above. The hashed bar at the top below the scale represents the frequency band. Below the frequency band the basebandsare displayed. For each baseband its position, its bandwidth (nominal and effective)as well as the baseband spectral windows are displayed.
When a baseband is selected in the BaseBand Configuration panel the display zooms in on the graphical representation of the baseband. Tick boxes can be used to determine which additional information (Lines, Receiver Bands, Transmission) is displayed and how the information is displayed. If checked, the Fold Basebands and Fold Spectral Windows control allows the tool to draw basebands with non-overlapping ranges to be drawn at the same y coordinate. This potentially allows more vertical space to be used for each element in the display, which can improve clarity. An example of a baseband visualisation can be seen in Figure 10.3 .
The buttons marked Zoom to Receiver Band and Zoom to Selected Baseband will zoom the display to the respective range. Checking the Track selection control means that whenever a new baseband configuration is selected in the tabbed pane to the right, the display will zoom to that baseband.
