Configuration
Grid
Four possible types of grid are proposed with different corre-
sponding values, some of which are fixed or non- applicable,
others editable. The type Conventional and the option None
do not give access to the parameters of the Grid sub-menu;
the others give access to certain options, as shown in the table
of the figure :

Note:
The maximum real number of channels for ITU grids depends on
the value selected for the first channel and the spacing between the
channels.
Note:
It is possible to display the grid with the View Grid softkey. A table
appears showing the channel number, the name of the channel, the
reference wavelength and the alarm thresholds for delta frequency,
minimum power and maximum power.
