New Rigol DS2000-S series with built-in dual-channel 25-MHz AWG

[marmad]

We discovered this over in the Rigol DS2000 review thread - but I thought it warranted a new thread. New S versions of the DS2000 series are coming out, with built-in dual-channel 25-MHz AWG

Any thoughts on what physical (dual) output they will use? Two new dedicated BNC connectors on the front/rear panel?

Price is ~$1,100 for DS2072-S

Looks great. I hope there will be no bugs.

Nice! I like the integration into the screen design.

Very inconvenient!
But not a show stopper.
Agilent started an awesome trend here.

It's got full ARB capability, but will that be usable? i.e. using a waveform capture or download?
They are most likely sharing technology from their DG2000/4000 function gens.
They won't want to step on the toes of those products too much though.

I'm curious how it will work. The docs mention internal storage capability of 4 waveforms.

Yes, I hate back BNC connectors... but I guess they're saving that knockout in the front for an MSO module some day.

Rigol is really raising the bar. Now they just need people's confidence to compete with the bigger manufacturers. Some people around here still hate their support depertment. I fear for Tektronix's long-term future. (Will they be here in 20 years?)

Unfortunately, Tek are almost insignificant in the low and mid range scope market now, and this just pushes them further down the ladder.
And rumour has it they have nothing on the cards to compete with.
I hope that's not the case.

I don't see any references in the Rigol Chinese or Tequipment docs to this enhancement in the DS2000 firmware:

3.      Added option for power analysis (PC software)   E

It really is a classic tit-for-tat between Agilent and Rigol.
Clearly going to be a copy of Agilent's excellent PSU analysis module.

Funny!    And I mentioned in another thread that it seems as though this change in the latest firmware:

14.      Changed the RUNT to standard trigger    M

seems like a direct response to the GW-Instek GDS-2000A (which includes the RUNT trigger as standard).

[ivan747]

I have noticed Rigol started copying certain aspects from different manufacturers. For example, the DS1052E's front panel looks like Tek's low-end offerings but the location of the buttons and knobs resemble Agilent's. Now they are trying to design their signature front panels. They use a lot of diagonal lines and an aggressive style. But they failed at that with their line of  programmable power supplies.

Agilent has created their own rival pretty much in the same way Apple gave Microsoft a place.

Nice I hadn't seen that feature.  If it works as well as the other brands, I'll be using it a lot.

So with this AWG, at ~$1100 it's about $250ish more than the normal model.  On paper it seems to out perform their base model DG1022 20MHz dual channel AWG in every way, and for around $100 less.  I'm guessing there's no input for modulation, and at first glance there doesn't seem to be a sync output? Albeit most of the time you're syncing with the scope anyway which I'm sure you could do internal.

[ivan747]

Dave, do you think you will be able to get a hold of one of these? I'm sure we all want to see it compared to the Agilent 2000 X series AWG and see how did Rigol integrate the AWG in the GUI.

Yes, the DS2/4/6XXX, DG4XXX, and DSA8XX series all look like they came from the same industrial designers - but the DP1XXX series doesn't.

Agilent 2000 X has no arbitrary generator now. Rigol's generator is overall better.
But in Agilent 2000 X there are many hidden features that may be enabled by new firmware, if Agilent guys decide so.

I fear for Tektronix's long-term future. (Will they be here in 20 years?)

I am not afraid. But they will have to come up with some new very upgraded version of DPO2000.

No idea.
I could ask.
Hassle @RigolTechUSA till he sends me one (and one for Marmad while we are at it!)
I'm sure I could eventually get a loaner from John South at Emona.

Perhaps this was mentioned in another thread somewhere - but I couldn't find it in a search. And it may be tangentially related to this same topic (connected to more UltraVision 'add-ons' that have yet to be unveiled), but while searching around online I noticed that there appears to be a concerted push to sell off Rigol's older MSOs. Both Batronix in the EU and Tequipment in NA have clearance prices listed.

I'm desperately trying to get Instek to provide a demo unit to Dave for review.  It makes me sad now that everyone talks only about Agilent and Rigol -- because Dave hasn't done a review on Instek yet!  Ah well, I hope to get that changed soon.

Greg, you seem like an objective, intelligent, and articulate guy - you could just do a review yourself as well. There wasn't any info available online about Owon's SDS line when I made my SDS7102 review (and thread here) 18 months ago, and even though I didn't end up keeping it myself, the review triggered a wave of sales and new owners of the DSO - who've since enlarged that thread into the 4th biggest one here. So it doesn't have to be Dave who gets people talking about GW-Instek
