A
Output Display
The Output Display is a two-line backlit LCD that shows output amplitudes, frequency and
Calibrator status. Output values (or potential output values if in standby) are displayed using up to
six digits plus a polarity sign. Output frequencies (or potential output frequencies if the 5080A is in
standby) are displayed using four digits. Calibrator status is indicated by displaying the following
abbreviations:
OPR Displayed when an output is active at the front-panel terminals.
STBY Displayed when the 5080A is in standby.
u When you change the output, a “u” (unsettled) is displayed until the output settles to
within the specified accuracy.
C Displayed when unstored calibration constants are in use.
B
Control Display
The Control Display is a multipurpose backlit LCD used for displaying data entries, UUT error
adjustments, softkey labels, phase angles, watts, power factors, and other prompts and messages.
When there isn’t enough room on the Output Display, output frequency is displayed on the Control
Display. Softkey labels identify the function of the softkey directly below them. Several softkey
labels together are called a menu. The changing menus provide access to many different functions
through the five softkeys plus the PREV MENU key. (See “Softkey Menu Trees” in Chapter 3 of the
5080A Operators Manual.)
