Repairing and Recovering Option Data
License, option, and model number data are stored in an EEPROM on the frequency reference board and
written into the gen.lic file on the hard disk drive. If the data stored in either of these items is lost, it can be
recovered from the other item.
NOTE If the data on both the hard disk drive and the frequency reference board is lost, it can not be
recovered. Contact Agilent for assistance. Refer to “Contacting Agilent” on page 2-10.
Recovery of Data After Repair
• If the frequency reference board is replaced, use the
Repair selection to recover data that has been lost
as a result of the repair:
1. Select
Repair from the Option Enable menu bar (see Figure 8-5 on page 8-14).
2. Click the
Freq Ref board has been replaced check box.
3. Click
Begin Repair. The data is written from the gen.lic file into the EEPROM.
• If the hard disk drive is replaced, a new gen.lic file is automatically created when the
Network Analyzer
application starts, by retrieving the data from the EEPROM.
Recovery of Data if Option or Model Numbers are Incorrect
If the analyzer option or model numbers are not listed correctly on the analyzer display, in either the Option
Enable Dialog Box or the About Network Analyzer display, you should regenerate the options license file,
gen.lic:
1. Exit the
Network Analyzer application.
2. Remove (or rename) the existing gen.lic file:
a. Open
Windows Explorer and navigate to C:\Program Files\Agilent\Network Analyzer.
b. Delete (or rename) gen.lic.
3. Exit the
Windows Explorer application.
4. Open the
Network Analyzer application. The application will generate a new gen.lic file when it starts.
5. Check the option listing:
a. On the
System menu, point to Service, and then click Option Enable, or
b. On the
Help menu, click About Network Analyzer.
NOTE If the options are still not listed correctly, contact Agilent for assistance. Refer to
“Contacting Agilent” on page 2-10.
