Rigol's New Function Generator and DMM: DG800Pro / 900Pro / DM858

[PELL]

Looks pretty decent to me    (not really)

Update: I purchased one about a month ago, and here are some teardown photos

https://www.eevblog.com/forum/testgear/rigol-new-dg822pro-teardown

Currently the software on this is an disaster, so pls don't buy it.


Here are some main specs:

DG800Pro: Up to 50M, 625MSa/s, 16-bits resolution, 20 harmonics max.
Starting at $280 (trans from CNY), possible $299 in global

DG900Pro: Up to 200M, 1.25GSa/s,  16-bits resolution, 20 harmonics max.
Starting at $680 (trans from CNY), possible $699 in global

One thing I personally interested is the Amplitude: Up to 20Vpp at high impedence or 10Vpp at 50 ohm 

Edit: The DMM part I put it on the latest reply in this thread

[PELL]

here is the 900 Pro and some more

[PELL]

Foegot to mentioned it also comes with a Frequency Counter

DG800 Pro: 7 digits, Up to 500M

DG900 Pro: 7 digits. Up to 1G

Nice DHO900 styling -- "collect 'em all!" 

But I will never understand what the Rigol designers were smoking when they introduced those circular number keys. How am I expected to enter numbers there?! What's wrong with the rectangular arrangement used on calculators or phones?! Who wants a lab instrument that looks like a toy? I am flabbergasted that they kept this absurd button arrangement on the new series.

Now, how to make Bode with the DHO804+DG800

Now, how to make Bode with the DHO804+DG800

I think someone can make a Python script using the LAN SCPI to control both instruments and draw a Bode automatically

[PELL]

And I found this Rigol patent from The China Patent Office

The patent name is "DMM", so there might be another DHO-liked product coming soon!

Personally, ridiculous numeric keypad layout aside, I'm very pleased to see this.  Since first sight of the DHO 800/900 series I'd hoped Rigol would leverage the form factor for other instruments.  And, hopefully, here we are and much sooner than expected.

VESA mount and external USB power.  Very bench space friendly, compared to the "shoeboxes" we've been accustomed to for signal generators, counters, bench DMMs etc.

UI consistency with the DHO series suggests that Rigol has settled on Android-based platforms for future development.

Thanks OP for sharing.

Rigol should offer a rail for wall-mounting the new instrument lineup, like this Braun/Rams classic.

I miss the CMOS level output with 15V unipolar in today's generators.
Or a little more "power", e.g. to be able to drive small transformers directly or gates from Mosfets/IGBTs.

I always ask myself what is missing when something is very small.

Who wants a lab instrument that looks like a toy?

Consent.
I like the display and the arrangement, but the right-hand side with the buttons...
I find it confusing and visually unsuccessful, especially when it comes to white letters/numbers on a black background.
Otherwise, "case recycling" is an interesting idea, scope, generator, multimeter, possibly power supply unit, spectrum analyzer...
You then have to take a closer look at which device you need to switch on.

In the good 'ol days of HP, probably a honking great toroidal transformer and with it, a high quality, low noise linear power supply.  But that was never going to happen here.  So all that's really gone is probably yet another generic SMPS.

In my opinion a good few "second tier" instrument manufacturers have just been following suit with accepted cases with bail handle designs for years.  If it shares HP/Agilent aesthetics, it must be as good, right?  It's refreshing to see some innovation and some outside the box (case?) thinking.

If you've used a DP832, it works, its not as good as a number pad but it is usable. You easily adapt as the numbers are in order, and A/mA, V, mV are straightforward locations (and are really useful since you can hit '5' -> 'V' as you would type it out). I still agree a normal numpad would be better.
Here? It does seem a wilder of a choice. Where is the V button? Its just M/G/k/hz. So its easy to type in frequency but not easy to enter a voltage.

DG4000 for comparison:


Now on to the real question.. is the hardware of the DG800pro and DG900pro going to be the same?

I think most of the parts will be the same. It should based on the RK3399 + ZYNQ + Rigol's own ASIC and running Andriod just like DHO scopes.

About the ASIC, Rigol mentioned it in their release press. It was integrated with wave-gen, amp, variable filters, protection, etc.

So... this thing is likely hackable

But one thing they might do is let the weaker (defected?) ASIC goes into the lower 800 Pro? Not sure though

Anyway, it will be available in China from late November. Hope someone can get one and take it apart.

*IF* the touch UI is well implemented, it becomes somewhat of a non-issue. If.

Cue speculation, complaints and 10 pages of hacking suggestions regarding fan noise in 3, 2, ..

Is anyone able to access the data sheets for these instruments from the international site (rigol.com)?

Links are provided on the product pages but these are currently timing out for me.

Unfortunately the specs sheets are only avalible in Chinese at RIGOL China website and you need to sign in to download it.

However if you do interested in the specs, I download it and upload to Google Drive here (Chinese Language Only, might need a translator)

THD<0.1%("Audio  Range")....Not bad.

[nctnico]

Unfortunately the jitter specification is not just bad, it is laughably bad. On par with the UNI-T UTG932

THD<0.1%("Audio  Range")....Not bad.

Not really spectacular either..

16 bit generator I have has cca. 0.015% THD in audio range at 1V RMS, measured with Pico4262 at 100 Hz, 1 Khz and 10 kHz..
And that is not low distortion audio gen, but a gen purpose AWG.

Distortion on DG800Pro / 900Pro should be measured, this spec is not as good as it should be for 16Bit Gen.
My old DG1000Z (14bit) is close to that.

Low distortion gen in Pico is 0,002-0,003% (90dBc) THD, two orders of magnitude better. And that measurement is limited by scope inputs.

But honestly AWG is not best tool for super low distortion signal anyways.
For general purpose use even 0.1% is more than good enough.

Totally agree, I would expect they can set a new benchmark performance at entry-level market.
Maybe they just can't reach that performance with custom ASIC

[MathWizard]

I would like more spacing between the big main digits, or between groups of 3, and bigger decimal's, maybe another rounder font so they don't blend together so much. I think that would be annoying/hard for some people to read even from 3-4ft.

How do Siglent's compare ? I have a sdg2142x but it's my 1st AWG. I'm thinking about getting a faster 1, upto 500MHz, like the sdg6000 series. Then useless +1GHz models drop a lot in price in the next few years, whatever I get next will probably be my last AWG.

I don't own any Rigol stuff yet, but I do like some of it. But then again I have Siglent scopes, so their AWG pairs with their scopes.

[Martin72]

How do Siglent's compare ?

Rigol 200ps, UTG932 150ps, SDG2000X 150ps, SDG6000 100ps, SDG7000A 10ps, R&S HMF2550 <1ns...
