The mistake I made in buying the 2072 is the very slow rise time 5ns,I need a faster rise time my cheap Siglant scope that I chucked in a cupboard has a5ns rise time and it cost $270 AU.
A couple of things I found out from RIGOL China is:
/DS2000 can only have a max of 2 trial updates then that's it
/there are at least 2 versions of 03 software.
/a new version of 03 will come out which you will not lose the trial versions when doing a Re Cal.
/I have not found away to put more than 2 Re Cals. in.
/You lose the ability to use Official Trial versions if you do the Trial reload.
RIGOL China is very helpful at first but if (good English used) if they can't solve the problem in 3 emails they start talking pigeon Chinese English. This is used to stop you asking for more Help I think
I am still going to pester them though.
