Installing the Agilent 8702D
Step 14. Copy the EEPROM Disk
Step 14. Copy the EEPROM Disk
The Agilent 8702D is shipped from the factory with an EEPROM backup disk
which is unique to each instrument. The backup disk contains a copy of cor-
rection constants which were stored in the instrument’s internal memory at
the factory. If your Agilent 8702D should ever be damaged, these correction
constants may need to be reinstalled from the disk. Use the following proce-
dure to create a backup copy of the disk.
1
Insert a 3.5-inch disk into the Agilent 8702D’s disk drive.

. Use the RPG and the
SELECT
LETTER
softkey to rename the file “FILE0” to “N12345” where 12345 represents the last
5 digits of the instrument’s serial number. (The first character in the file name
must be a letter.) When finished, press
DONE
.

Label the disk with the serial number of the instrument and the words
“EEPROM Backup Disk”.
Whenever the Agilent 8702D is returned to Agilent Technologies for servicing
and/or calibration, the EEPROM backup disk should be returned with the
Agilent 8702D. This will significantly reduce the instrument repair time. The
EEPROM backup disk procedure is now complete.
