STEP 6. Back Up the EEPROM Disk

STEP 6. Back Up the EEPROM Disk

Description

Correction constants are stored in EEPROM on the A9 controller assembly. The advantage
of having an EEPROM backup disk is its capacity to store all the correction-constant data
to a new or repaired A9 assembly without having to rerun the correction-constant
procedures. The HP 8753E network analyzer is shipped from the factory with an EEPROM
backup disk which is unique to each instrument. It is prudent to make a copy of the
EEPROM backup disk so that it can be used in case of failure or damage to the original
backup disk.
