Figure 13-2. SECURENET Options Screen
13-3 BASIC OPERATION
Control of the unit and selection of data to be
displayed are done through the use of three
main windows which simultaneously appear
on the screen: the Display Zone, the RF Zone,
and the Audio Zone. These three zones are
shown in figure 13-3.
The top portion of Display Zone displays the
status and selections for the current test
sequence. The bottom portion of the Display
Zone displays the data about the radio under
test.
The RF Zone is used for selection of RF
mode, for selection of frequency band, for
port selection and for control of RF signal
level at the input/output port. The audio
section is unchanged from the standard
system except that, in SECURENET mode,
modulation options are limited.
13-3.1 Display Screens
The three main windows, or cursor zones, are
accessed through a cluster of three CURSOR
ZONE keys at the top center of the unit. The
location where the cursor rests within each zone is
called a cursor field. To control the unit and enter
data, all operator inputs are made at highlighted
cursor fields (brighter-face type).
Below the screen are softkeys. These softkeys, with
customized on-screen labels, interact with the
screen to provide a unique menu of entry options
for each cursor field. This greatly reduces the
number of keys and eliminates having to search
through unrelated controls to find the one that is
needed.
