your statement is not wrong, but i guess in this case, it has nothing to do with attenuation setting in FW (FW just multiple the signal accordingly) nor a 1x coax cable. i was using the same 50 ohm termination setup (no cable),

Oh, duh, you're using a cable not a probe...  :palm:  :-DD

It was a knee jerk reaction to "I get different results in 1x mode then 10x mode".

Makes sense.

Nice, those look great!!

Any chance you could show the 10 bit and various ERES modes with this new scope?

Best,

No 10 bit mode in this one Mike but study the screenshots in the SDS6000A thread.  ;) This thing has some nice tricks.
Not played much with ERES yet but will post something when time allows in the 6kA thread.

JohnG:
Those transition times (~250 ps) seem rather long for a 2 GHz bandwidth scope. I saw that the spec is 230 ps, but the 1 GHz version of the scope is 350 ps. Whatever they are doing to get the extra bandwidth is not helping the risetime nearly as much.
