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 3-40 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.
