Just think of it as a X2000 replacement, just more memory length.
Not bad for a X2000 lower cost replacement though, 1 thing i don't like is well, it's not a agilent  :P and it's in the infantile stage now so nobody's got their hands on it yet as far as i know

"DS2002A

Well that's one way to undercut the competition!

Anyone else think this isn't such a great deal? I mean, the larger screen and depper memory are nice, but is it worth 3 times as much as the DS1102E of the same bandwidth?

It's waveform update. That's the deal straightener

Definitely not the scope for beginners that is.

Another drawback: no real SPI decoding, as you can't use ext. trigger as CS. Hameg 2ch scopes can do this...

Besides I'm still confused that the manual doesn't clearly mark the optional triggers as "optional".
Windows trigger, Nth edge trigger, HDTV trigger, delay trigger, timeout trigger, duration trigger and USB trigger are all only optional (AT-DS2).

I think this is very attractive if you need 200 MHz.  No other scope I've seen can do 200 MHz+2 GSa/s+Deep Memory at that price.

Is it completely sure that the full record length is available at full sample speed? I mean this was also proclaimed for the Owon SDS when it came out but later on it became clear the this was not the case.

Besides: while the large buffer is surely cool, it would be much more useful if you could search it and measure at least manually with 6 digits or so. Truncating even the manual measurements to 4 digits (e.g. 100.1µs) kinda cripples the scope's performance. This is even worse in the DS4000 line of course where you have up to 4GS/s and 140Mpts and still you can neither search nor measure anything exactly due to the weird 4 digits truncation (ok, agreed, all the Tek DPOs limit to 3 digits, which is even worse).

deadbeef does have a point there, but it's still better then a Tek which hasn't been too well recently  :P

It's a shame with Tek. The DPO2000/MSO2000, which came down to affordable regions recently has just such a miserable screen resolution. And all the Tek DPOs, including the DPO3000 and DPO4000, truncate all measurements to 3 digits (e.g. 100µs) - even in cursor measurement. I just don't get why anybody would do this. Even the Agilent DSOX3000 - though measuring in the display buffer - has an "ok" resolution of 5 digits for automatic measurements (e.g. 100.01µs), but (as far as I recall) at least 6 digits for manual cursor measurements (e.g. 100.001µs).
Now if Rigol had copied at least the Agilents resolutions, I could live with that. And heck, they should implement that edge/pulse counter auto measurement and fix the cursor bugs in zoom mode.
Last but not least, I wished they released a 4ch DS2000 or offer the serial decoding options for the DS4000 a bit cheaper.

Yeah, in a lot of regards this is probably true - and yet still they cripple all time measurements on the scope by truncating times to three digits. While Rigol's crippling to 4 digits is not much better, it's still better by the factor 10.

I am not too happy with my Hantek/Tekway/Voltcraft crap China DSO that just permanently locked up because of software issues. So I am considdering selling the Hantekwaycraft and getting one of those Rigol DS2xxx series scopes instead.

Do you think the 4-Digit limit is a hardware limit or smth that could be fixed later in software? I also wonder how responsive the unit is, cuz the Hantek I currently own is not so great ... it doesn't seem to capture unperiodic signals all too well.

Well, the DS4000 is said to be quite decent and responsive, so I guess the DS2000 will be as well. However, the DS4000 still has some major bugs e.g. regarding cursor handling in zoom mode which make exact manual measurement more or less impossible at this point. So my bet would be that the DS2000 inherits a few bugs and introduces a few new ones and it will take the next 3 to 6 months to fix the worst of them (taking into account that the DS4000 is available for several months now).

Regarding truncation of measured periods: in manual mode, I'd say this is most probably just a GUI limitation and thus could be improved in SW. In auto mode, there could be a hw limitation as well - as the Rigol DS2000/4000 is very close to the Agilent DSOX2000/3000 chances are that they also copied the automatic measurement in the display buffer. Then again, the DSOX3000 measures at least with 5 digits, so there's a chance that the Rigol could at be as accurate as this - which would IMHO be satisfying for automatic measurements. On the other hand, as said before, the Tektronix DPOs truncate all measurements to three digits and obviously either nobody ever complained about this or they didn't care.

If there will be actually any improvement in the future is another question. I already tried to contact the Rigol support twice in the last weeks regarding this and other issues and I got no reply whatsoever. Not even an automatic reply. Furthermore there are no publicly available firmware updates. This gives me a bad feeling regarding customer support.

I've bought the RIGOL DS4000 a few month ago and noticed the cursor bug in zoom mode during discussion with 0xdeadbeef. After that I've sent a note to RIGOL support and got a reply the next day. They informed me that responsible engineers will be contacted in Bejing.

On Friday I've asked again if there are any news. Today they replied that RIGOL has accepted the cursor issue as a bug and an update will be available during the next 2-3 month. I'll get it automatically.

So, from my point of view, I had no problem to get in touch with RIGOL.

I agree with 0xdeadbeef that truncation of the decimals could have been implemented better.

regardless of how good or bad is your DSO, when the manufacturer is asking endusers to install important patch
to fix serious issues don't blame the manufacturer for locked device only because you was too lazy.
And btw, you do have warranty, you don't need to sell it.

I also wonder how responsive the unit is, cuz the Hantek I currently own is not so great ... it doesn't seem to capture
unperiodic signals all too well.

a basic understanding of "how to use oscilloscope" will probably help you more than 50k USD DSO.

Indeed, I got notified by Conrad that the Scope might lock up when you shut it down in the 80mS/DIV setting. So I avoided using that range. It still locked up. I guess I could send it in.

I am just disappointed ... or well ... let's say maybe I expected too much from such a cheap unit [not talking about the lock up here]. It's my first DSO. I've mostly used TEK analog scopes before. It may also be possible that I am just a moron who doesn't know how to use such a scope in a way that it gives me the results I want. I remember trying to measure some voltage and the scope trace only jumped up briefly and didn't really display much, or it took a long time. That's why it feels sluggish to me. I can't remember the exact circumstances of the measurement, but that's how I felt about the scope.

Sorry my English and my short term memory is too limited to describe this matter in a more precise way.
