AndersAnd,
Thanks for the reply. I noticed that you suggest upgrading the firmware to the latest, yet others are concerned that one of these days the latest firmware update will prevent using keys that allow upgrading any farther than the instrument you purchased. I just requested a firmware update and they asked for my FW#, model, and serial number. I suspect it's only a matter of time before Rigol takes affirmative action and we're talking about the "good old days" of hacking an upgrade.
My current firmware is 00.01.00 and the HW is 1.0. These sound pretty early compared to others on this blog, yet I only purchased it April of this year.
