SYSTem: OPTion:UNINSTall is deleting "All official options removed" or something like this.
But after some mem dumps I found 36 Hours Trial License Key ... key. Like for DP832
there is the same for DS1054Z too in here
http://www.gotroot.ca/rigol/riglol/And this is V for generating trial keys for DS1054Z
Option VSER is all options like DSER but 36 hours trial version.
So others can be
DS1000z device options:
first character: D = official, V = trial
DSAB - Advanced Triggers
DSAC - Decoders
DSAE - 24M Memory
DSAJ - Recorder
DSBA - 500uV Vertical
DSEA - 100MHz
DSFR - all options
DSER - all options - 500uV Vertical
Currently I have DS1000Z-00.04.04.00.07 firmware.
Now if I add official license, all options are official and after delete
all options continue trial time. (and mem dump is messier at key regions
like he is generating all separate trial keys but factory ones are there too. )
