Yes, I did believe that, simply because I could not think of any other way to get reliable triggering at high frequencies – and as we all know, I think the trigger system of the SDS2000 is hard to fault and certainly one of its strongest points, but…

The trigger system in any DSO works by detecting whether a threshold has been crossed. The values of the samples where the threshold crossing occured are stored and used to calculate (interpolate) the exact trigger point and required shift to adjust the time reference of the samples so subsequent acquisitions overlap eachother perfectly and the signal is properly aligned with the trigger point.

Typo?

What you describe is the traditional analog trigger architecture.
We are talking about the SDS2000, which incorporates a fully digital trigger system.

Yesss :)
Can you imagine what the 1GSa/s recording would have looked like at 500MHz? :)

;D
Will you examine the Power Analysis option?
