Backup Licenses

When the licenses for frequency range and other options are installed in the
instrument they are saved in non-volatile memory on the A5 CPU assembly.
Before the instrument was shipped from the factory a backup copy of these
licenses was also saved on the A3 RF assembly. If the A3 RF assembly is
replaced, the licenses that are in the A5 CPU non-volatile memory will need to
be backed up to the backup storage location in the new A3 RF assembly, so
that there will be a copy of them in case the A5 CPU assembly should ever
need replacement.
When an A3 RF assembly is replaced the following error message will be
displayed until the licenses are backed up:
