3-4. Menu and Softkey Overview
There are several keys labeled (FREQUENCY, SYSTEM and MARKER…etc) on the front panel of the
LPT-6000 Spectrum Analyzer designed to execute specific different functions. Pressing a front
panel key accesses a soft key menu that is located along the right side of LCD display.
Softkey menus allow access to a list of related functions to the ones obtained by pressing directly
on the front panel keys. Pressing the unlabeled keys, also called softkeys, immediately on the right
of the annotation screen will activate the functions on the softkey menu.
The function becomes active when the value of the concerned softkey menu can be
changed. Activated functions appear on the LCD screen in the active function block. For
example, pressing the FREQUENCY key will display a softkey menu of related functions on
the right of the LCD screen. Pressing the softkey corresponding to Start Freq will result in
the “Start Freq” being displayed in the active block.
Softkeys with ON and OFF allow the user to turn a function ON or OFF
Softkeys with AUTO and MAN allow the user to auto-couple or manually change values using the
