The screens look nice on that.
When you go in on the timebase, what happens to the trigger position?
I use a Tektronix TDS220 at work which can be utterly infuriating when you change the timebase, it moves the trigger position. Consequently, if the trigger position is off centre, by the time you're down to nanoseconds the bloody cursor is milliseconds "off the screen", and the only way to bring it back on screen is to go back up the timebase and then move the trigger position into the centre before going back to nanoseconds.
Wonder if there's any vids of your scope working? With the "slow" options off, what's the response like?
I could do with a scope at home.
