Calibration and Passwords
Calibration is not required after the mainframe has been repaired.
All calibration information is module-specific and resides in each
power module.
However, if the A5 board that contains the calibration switches has
been replaced, any calibration password that has been set will be
lost. Passwords that are used to prevent access to the front panel
Admin menu will also be lost.
The calibration password will automatically be reset to the factory
default, which is zero (0). Front panel access to the Admin menu will
be unrestricted unless a password is set.
Refer to the User’s Guide for information on setting the calibration
password as well as the Admin menu password.
Initialization
The power system's model number, serial number, and other
constants that are required to program the instrument are stored in
an EEPROM on the A5 board. If this board is replaced, the
instrument must be re-initialized.
To initialize the power system, you must send the following
information to the power system over the interface:
DIAGnostic:FRAMe:ATTRibute "ModelNumber", "value"
where “value” is the model number, e.g. N6700B.
DIAGnostic:FRAMe:ATTRibute "SerialNumber", "value"
where “value” is the serial number located on top of the interface
cover.
At power-up, the power system will go through the turn-on self test
sequence. All other parameters will be set to the factory defaults. The
mainframe is now initialized.
