General Key
Descriptions
This section explains the function of each of the terminal interface’s menu, menu
control, and editing keys. If a key is not functional in a particular situation,
pressing that key does nothing except to cause a beep.
Menu and Menu
Control Keys
Label menu choices for corresponding function keys.
Returns to the Select an instrument menu.
Returns to the previous menu level within an instrument menu or escapes from
an input prompt. When you reach the top of an instrument’s menu, the
PRV_MENU label disappears.
The screen can show a maximum of five menu choices at a time. When there are
more than five menu choices, function key f6 becomes labeled MORE. Press
MORE to display the next group of choices. By repeatedly pressing MORE you
can display all groups of choices. After you have displayed all groups of choices,
pressing MORE again returns to the first group of choices.
Recalls the last command entered from the terminal interface. After recalling a
command, it can be edited or re-executed. You can recall from a stack of
previously executed commands by repeatedly pressing RCL_PREV. When you
reach the bottom of the stack (the last line in the buffer), pressing RCL_PREV
does nothing except to cause a beep.
Accesses commands in the opposite order to that of RCL_PREV. Pressing
RCL_NEXT does nothing until you have pressed RCL_PREV at least twice.
Recalls the last SCPI command generated by a menu operation. For example,
reading the time using the menus (SYSTEM, TIME, READ) generates and
executes the SCPI command SYST:TIME?. A recalled command can be
executed by pressing the Return key. You can also edit a recalled command
before you execute it.
Performs the same function as PRV_MENU.
