First oscilloscope: DS2072A or DS1047Z?
sgofferj:
Hi,
I have read the "Newbie read here first" post. I have searched plus skimmed about 30 or 40 pages manually but I didn't find an answer to my question. If there is one which I missed, feel free to shout at me!
Here is the deal: I'm more or less an electronics hobbyist. I tinker a lot, mostly digital, i.e. Arduino & similar. I recently started doing some more "professional" development of some open source software and hardware and I feel that I should have an oscilloscope. The last 4 or so weeks, I have been googling, watching Youtube videos, etc...
I was fairly sure that I want to buy a Rigol DS2072A and asked the Finnish dealer for a quote. They said, it's not on stock and it would take long to get but they have the DS1047Z on stock and it would be cheaper and maybe better suited for my needs.
So I have read about the DS1047Z - and read about 1/3 of the Rigol megathread (reading backwards)...
And I have no idea what I should buy now... I'm just not deep enough in the topic. What I'm sure of is that I want to buy something that I can use for a few years, i.e. I don't want to "outgrow" it in a couple of months. I think, the main question for me is - for my purposes - do I rather have 4 channels (DS1000Z) or 300MHz (DS2000A)? Will the 100MHz of the DS1000Z series be enough for my future needs?
Basically, I'm looking for opinions of people who are standing where I will (hopefully) be in a few years...
-Stefan

I can see some confusion here. First, it's DS1074Z and not DS1047Z. Then, both 2072A and 1074Z are 70 MHz scopes (that's the meaning of the 07 in their names). So, you have to choose between the 4 channels of one and the better functionality of the other. But this is a choice that only you can make. You're not likely to outgrow any of them in a matter of months.

Did you look at the Siglent SDS2000 series? 4 channels and twice the samplerate the DS1000Z series has.

Siglent SDS2074 RRP US$1168 plus taxes if any

Whoops, typo. Could you elaborate on the better functionality? I am still searching for a good YT video detailing the 1074Z. As I wrote, I don't really understand that much about DSOs. I have learned 25 years ago on analog scopes :).

No, I haven't seen those yet. Unfortunately, also almost twice the price. I try to stay below €850 (soft limit ) or €1000 (hard limit). There would have to be a real valid reason for me to go over the "hobbyist budget".
