17-3 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 17-3.
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 ASTRO mode, modulation
options are limited.
17-3.1 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.
