Backing Up License Key File
The license key for some options are kept in a text file (.lic) located at
Factory(E:)\LICENSE\. The E4990A refers to the license codes in all of .lic
files under the directory.
If there is no license code, an error occurs and the E4990A measurement
application works as simulator only.
When you change the storage, copy the .lic files as back up. You can re-
create the license number at http://www.agilent.com/find/softwarelicense
