HP54645D now- which Rigol next?

(1/4) > >>

reagle:
I've been getting by with my much loved HP54645D for a long time now, but the lack of deep memory is starting to get in the way. I am torn between basically three options-DS1202Z-E, DS2202A or HDO1102.
Of these I am the most familiar with DS2202A and it seems like by now they got the bugs out. Less certain on the other two, especially the shiny new HD model. My use case is general debug, maybe looking at buses like QSPI, some analog.  This is used for work, so ideally not too many showstopper bugs and just generally reliable hardware. I can see larger screen on HD may be helpful in some case, not convinced 12 bits does much for me. Thoughts/pointers what to compare?

I’m thinking you might need to keep an HP/Agilent ‘fix’ as well as a modern scope. Do you have the digital probes? Have you considered trading your scope for the respected 54622D? More speed, more triggers, hi-res screen. And for the modern scope, are you sold on Rigol? Have you considered the Siglent, GW Instek, Micsig options? If you are probing buses, I’m curious why you shortlisted only two channel variants?

I do have the HP digital probes puck, but with modern tools like Saleae I don't think I've touched the digital channels on HP from early 2000 ;)  Just wondering - is there something that my HP still does better than modern scopes (besides playing invaders game on CRT that is)? I've used 54622D as well, but I think something more modern is in order.

Rigol consideration is mainly due to the fact I am the most familiar with them/their interfaces. Had DS2xxx series as a daily "driver" for years so that makes me look at their stuff. Heard of Siglent, never used them. 2-4 channels is mainly pricing. 4ch Rigol in HDO gets expensive, though I just discovered the MSO5074 as another option. That one is an interesting beast. Instek used to be pretty crappy last time I dealt with them. And of course lower end big names are just way too expensive. Which Siglent would you look at, 1104X-E?

Funny enough there was a similar thread in 2014 and consensus was  to keep HP. I bet things have changed a bit since then!

Why not the Rigol MSO5000?

It's in the same price range as the others but has higher bandwidth*, 4 channels for looking at buses plus MSO option if you ever need more digital channels.

(*) Assuming you're going to hack it.
