Data Display
The data display area is the large LCD touch screen. The touch screen is used to display measurements and
function menus. The touch screen has the ability to receive input from the active soft-keys with a simple press
of a finger. The majority of your interface with the analyzer is through the touch screen. Refer to Section 3-3 for
more information about interfacing with the LCD touch screen.
Front Panel Keys
The front panel keypad is used to set the analyzer in and out of standby operation, enter numerical data,
activate functions, and access menus on the GUI. The keypad is divided into groups consisting of the Major
Function Keys, Minor Function Keys, and Numeric Keys.
Major Function Keys
The major function keys are located along the right edge of the front panel and are mapped to key
functions of the instrument that are used most often. These keys activate basic functional parameter
setups and second-level menus found on the GUI. Each of the major function keys have default
parameters associated with them. The default parameter is available for adjustment via the increment
keys or rotary knob after the function is activated. The key becomes illuminated when it’s function is
active. The following list describes each of the key’s functionality:
Frequency: Use this key for accessing the frequency menus. The frequency menus
allow you to set the center, start, and stop frequencies, frequency span, frequency step
size, and frequency offset. The default parameter is the center frequency.
Amplitude: Use this key for accessing the amplitude menus. The amplitude menus allow
you to set the reference level, attenuation parameters, graticule scaling and units
parameters, and the level offset. The default parameter is the reference level.
Bandwidth: Use this key for accessing the bandwidth menus. The bandwidth menus
allow you to set the resolution and video bandwidths, sweep time, and bandwidth
coupling factors. The default parameter is the resolution bandwidth.
Marker: Use this key for accessing the marker menus. The marker menus allow you to
select the active marker along with the marker mode and access the marker search
