Restore 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.
When the instrument is originally shipped from the factory a backup copy of
these licenses is also saved on the A3 RF assembly. If the A5 CPU assembly is
replaced the licenses that are backed up on the A3 RF assembly will need to be
restored to the A5 CPU assembly so that the proper functionality is restored to
the instrument.
