Yeah true in numbers the gap is pretty big. But in practice going from 10K to 1M is a massive difference, but going from 1M to 100M is not. For the ocasonal cases where deep memory is useful one can usually get around it with segmented memory modes.

They are one of the rare vendors that keep sample memory inside the ASIC  This limits the size of memory but gives it a huge speed
All depends on what you want from a scope.

The latter is true. For me the lack of deep memory is a deal breaker especially since the actual operational memory on the Keysight scopes is much less than it says on the badge. Sure you can make do with segments but even then you'll need a certain amount of oversampling for decode to keep working. On a scope with deep memory you can choose to use a short acquisition memory setting if you want a high update rate. On the lower end Keysight scopes there is no option to get lots of memory if you need it.

Well i don't know about the speeds of the Agilent MSO8000 series, but the MSO9000 is a lot faster running at Kilosamples of memory compared to Megasamples. What i consider fast on a 9000 is having a handful of acquisitions per LCD refresh period. In Megasample capture length that turns around to a hanful of LCD refresh periods per acquisition. And i still consider all of that slow when im used to the consistent lightning speed of a MSO6000.

So far i haven't seen the perfect scope that hits all the upsides in one scope, just like i have yet to find the perfect handheld multimeter. So for my needs i use a combination of a MSO6000 (Super fast, reasonable performance, great for day to day tasks and poking around) and MSO9000 (Much higher performance and broader feature set, used for the more serious measurements)

The speed of Keysight scopes you only really appreciate when you used one for a while and then go to a different scope. Much like 30fps video looks just fine until you watch 60fps video for a while and get used to it and then watch something 30 fps again. Im not saying other scopes are slow, just that they are not quite as quick as Keysights (Its the subtle differences mesured in 10s of miliseconds). I'm not a Keysight fanboy or anythyng, its just that i happened to end up with two scopes and got used to it. Scopes are expensive so i can't exactly keep 5 of them around from different vendors.
Mr Nutts:
Maybe kb memory feels faster on the Infinum 9000  probably because it samples with 10(?) Gsps while Infinum 8000 samples with 4 Gsps?   :-//
 
My Infinum 8000 feels fast which is nice. If only the touchscreen was a bit bigger ;)
 
My Lecroy LT374M a low waveform rate but it has great triggers which I find more important. At the end of the day it doesn’t matter if a scope is blind 98% of the time or “just” 82% because it will still be blind for most of the time. Good triggers find problems at their first occurrence ;)

Can you Hack the 1204G to 200Mhz and Full Options?

Are there some Easter Eggs on Keysight DSOX1000 series scopes? Like the easter eggs on DSOX2000 (Trek screensaver, Etch-a-scope, jumping letters)
