The lady from Rothsware told me that she knew nothing about the 5 year warranty and Farnell gives you only 1 year warranty.
The true problem is that when you buy something from Farnell, you don't know, how old it is... This is the back sticker of my scope. The 1225 means that it was manufactured in 25th week of 2012.
And yes, if i bought Rigol DS2000 or GDS-2000A today, I might get a unit from the beginning of production... That would not be good.
