Simple how to Unlock your Rigol DS 1054Z oscilloscope for all options.
For all new viewers of this video.
There is information available regarding the upgrade software code DSFR. The information can be found here http://www.eevblog.com/forum/beginners/upgrading-rigol-ds1074z-(1000z-series)-to-unlock-options/
It is suggested to avoid possible issues to use a code which is not shown on the unlock website. This code is DSER instead of DSFR. DSER will unlock all options but not the 500uV : )
