And with 4 cores and 3.6Ghz not the badest one.
Before we bought the waverunner and the HDO6034A (both with i5 cpu), we got a hdo4000 (intel i3) on loan for two weeks.
The scopes based on a pc platform are simply in a different league in terms of overall performance.
I work with the HDO6034A almost every day and everything is so smooth, so fast, it has 8(!) math channels, until now I had 4 of them running at the same time and nothing has changed in speed, just great.
Last weekend at home on my HD I had 2(.... :P ) math channels active at the same time (both with FFT) and a few readings in the display.
Well... ;)
You get what you paid for, even if it wasn't exactly little.
(Not to mention the unspeakable slowdown of the entire system when the Bode Plot is active).
But such comparisons bring you back down to earth when you think spending more money isn't necessary. 8)

It slows the system down - Nothing for unpatient users..

It also allows for more history waveforms :) i do it for both reasons. scope set at 12.5MPts, unless i need the samplerate at lower timebases

SDS5000X right Jack ?
Have you not installed recent firmware that allows setting of a fixed sample rate ?

Yes. I did, but i don't care for the function. I've always been content in how the scope operated out of the box and i'm used to it. I tried the other memory management modes but failed to find a scenario in which either would be an advantage over the Max Memory we all know and love (or a big enough advantage that i bother going through the menu to find the optimal setting from time to time)

Your initial statement was very clear. You stick to 12.5 Mpts memory except when you really need longer captures = slow timebase settings where the samplerate drops below your requirement for the acquisition bandwidth. So what you want is sufficient samplerate rather than constant samplerate - the latter is only useful in some very special cases, e.g. where the scope bandwidth depends on the samplerate in a less familiar way, such as in ERES mode.

That's what generally is considered best practice, as 10-14 Mpts is some magic region for all scopes based on that current Zync platform... ;)
