Set Internal Clock: Accesses softkeys that allow you to check and set the date and
time for the clock/calendar. This section describes how to set the time and date
under the heading "Setting the Internal Clock/Calendar."
Remote Port Setup: Opens setup menus for the IEEE-488 instrument control port
and the RS-232-C serial interface port. Section 5 describes how to set up the
IEEE-488 interface. Section 7 describes how to set up the serial interface. Either
interface can be used as the remote control port.

4-33. Format Eeprom Menu

Use the format EEPROM with extreme care. This menu presents
softkeys that permanently erase calibration constants. This
should only be required after repair of the instrument. Pressing
"ALL" or "CAL" invalidates the state of calibration of the 5790A.
For this reason, the CALIBRATION STORE switch must be in
the ENABLE position and the CALIBRATION MODE switch must
be in the SERVICE position for these operations.
Pressing "Format EEPROM" in the instrument setup menu opens the following menu:
The EEPROM is the nonvolatile memory device. (Its contents remain unchanged when
the power is turned off.) It contains calibration constants and dates, setup parameters, and
the user report string. Softkeys in this menu let you replace all or part of the contents with
factory defaults. In the case of calibration constants, factory defaults are the starting
defaults used for all 5790As. They are not the calibration constants obtained when the
5790A was originally calibrated by the factory before shipment. The function of each
softkey is described below:
ALL: Replaces the entire contents of the EEPROM with factory defaults. This
would be used by service personnel after replacing the EEPROM, for example. It
is not required in normal use. This softkey requires the rear panel CALIBRATION
STORE switch to be in the ENABLE position and the CALIBRATION MODE
switch SERVICE position.
CAL: Replaces all calibration constants with factory defaults but leaves all the
setup parameters unchanged. This is also not required in normal use. This softkey
requires the rear panel CALIBRATION STORE switch to be in the ENABLE
position and the CALIBRATION MODE switch SERVICE position.
SETUP: Replaces the setup parameters with factory defaults but leaves the state of
calibration intact.
To format a portion or all of the EEPROM, press the corresponding softkey. Formatting
the EEPROM is a two-step process where you are asked to confirm your intentions
before proceeding. The Control Display appears as follows:
