Correction Constants
Correction Constants
The analyzer stores many correction constants in non-volatile EEPROM
memory. These constants enable the analyzer to produce accurate, leveled
source signals and receive clean test signals.
Storing Correction Constants
After performing any adjustment listed on page 3-41 in this manual, store the
correction constants to a backup file on the analyzer solid state drive by
performing these steps:
— Navigate to the EEPROM Backup Utility, located at:
C:\Program Files\Keysight\Network Analyzer\Service\eebackup.exe
— Run the program.
— Click Backup EEPROM.
— Click Exit when the program has finished.
