Front Panel Features
Front Panel Display
The 34980A features a dual-line, alphanumeric display, plus a set of text and
symbolic annunciators to indicate operational modes and error conditions.
At power on, all segments on the front panel are displayed and all lighted keys
temporarily turn on. The front panel is ready for operation when the keys are no
longer lit and the green channel field on the display shows the first slot in which a
module is installed.
Displayed Messages
The two-line display is context-sensitive; the nature of information displayed will
depend on if you are navigating the configuration menus, switching between
module and channels or viewing measurements
Module and Channel Status
When not in a menu, use the arrow keys to scroll through the (up to eight)
modules installed in the 34980A, and the knob to scroll through available
channels.
With each press of an arrow key, the upper display line indicates at left the
channel in use, in the form sccc, where s is the slot number for that module
and ccc is the channel number. When you stop on any module, the upper
display line will display at right the module type briefly, then change to display
channel information. Scrolling through the modules will only show information
for installed modules, skipping over unused slots. For detailed examples of the
slot and channel numbering scheme used in the 34980A, see “Slot and
Channel Addressing Scheme” on page 213.
Menu Choices
During menu-driven operations (e.g. measurement configuration), the primary
display line indicates the configuration feature or menu, and the second
display line indicates the submenu, configuration choices or parameters. The
second display line also displays temporary messages, when exiting menus or
to convey configuration state changes.
