Rigol DHO800 memory depth / bandwidth upgrades and noise level!

(1/28) > >>

Bob773:
It seems like nobody is talking about how the memory depth cuts back when adding channels… goes from 25Mpts single channel to 10Mpts with 2 channels, why not 12.5?… then drops to 1Mpts with 3/4 channels?!!  This alone is a major deal breaker for me.  I use single triggers with multiple channels very often.  Anybody have insight to why this would be?

follow this guide hack the mem-depth, then you can get 10M at 4 channels

I tested it under firmware 1.01 and it works to me  ;)

We've all hacked ours to 50Mpts so we get 10Mpts per channel with all 4 channels on.

That's why it doesn't get much discussion - it's a non-issue!  :)

All you need is an Ethernet cable...

PS: While you're doing that "upgrade" you can also change the bandwidth of a DHO804 to 200MHz (measured).

Yes, but why do we lose 21M of memory on the 800 and 10M on the 900?

All we know is that it's a marketing decision not a hardware thing.
