OWON DGE2070 Arbitrary Waveform Generator Review/Teardown

In this video, I did a detailed review and teardown of OWON's DGE2070 dual-channel arbitrary waveform generator and compared it with the UNI-T UTG962E. One of the key advantage of the DGE2070 is its ability to store user generated arbitrary waveforms. If you are interested in getting a DGE2070 or DGE2035, you can find it here: ban.ggood.vip/13HAp

Great video Mr. Wong, awesome channel.

[@barrybogart5436]

When I had trouble getting a Win 10 driver for my old Hantek DSO, I bought an Owon HDS272S, partly because of the built-in WG. which is very convenient, although only single-channel. I don't need all the waveforms in the 2070, and I still have a separate Hantek AWG that does allow freehand waveform drawing. If I ever need it. The 272S is all I need for the moment, although I see they now have a 200mHz version! Thanks for your thorough review.

[@EdSym1]

You can program ch2 to output an arbitrary waveform as a pulse and use that as a trigger to see a sweep on an oscilloscope. You will have to use the utility menu to align phase also. You lose a channel on the signal generator and oscilloscope but it works.

[@andymouse]

A proper review of an 'Arb' !.....cheers.

[@johnwest7993]

If I had one I'd 3D print a frame to hold it at a convenient angle for easy reading and 1-hand adjustment. You are quite correct about its poor physical design when it comes to convenient usability.

[@-highvoltage4685]

Great video! I think you should review owon sds1102 100 mhz entry level oscilloscope, same price as the hantek dso2d10 you reviwed earlier. there is also another variant with 4 channels for about 250$ named sds1104

[@tonyh6309]

Good review. The 210MSPS AD9744 is "only" $12.44 @ 1K from AMD but still too expensive for this product. Interestingly the AD9746 dual DAC is only $17.73 or $8.87/channel and is specced at 250MSPS (so no overclocking required) with much better INL and lower noise. The SFDR is worse at 80dB compared to 90dB which might be an issue although the output amplifier performance may present more of a limit than the DAC itself. I imagine that OWON would get much better than list prices but even $5/channel still represents a big chunk of the $147 selling price. You have to wonder at the marketing decison to veto a trigger output which would make the product somewhat more versatile at an added cost of maybe only $2 or $3 to the end customer. I guess they assume that the market is mainly hobbiests where price is paramount. It would be good if your product reviews would note when the USB ports are isolated or not, given the risk of damaging the PC if the unit is mistakenly connected to the wrong part of equipment under test. Proper isolation costs a few more cents so is always a candidate for penny pinching.

[@askanyful]

Thank you for the video. I need an arbitrary function generator for research and testing in my own lab. Which is a better choice?

[@jstro-hobbytech]

Great video as always. If it had some other options like fft I'm sure it would sell more but I realize that it's a big ask. This is unrelated but I'm wondering if you've tried the hantek current clamp to bnc? You're definitely right about bandwidth. I have a 70mhz and a 350mhz bench scopes and I've never come close to 50mhz. I sold my function generator arb when I got my new rigol with two 20mhz function generator output.

[@KerryWongBlog]

I have not tried the Hantek current probe. But I just tested Micsig's CP503 current probe a few videos back and it was quite good.

[@jstro-hobbytech]

@Kerry Wong yes. It seems everyone uses them. I find them pricey. I just bought a new rigol mso5354 and the logic probes so as a hobbyist that will be the last one I'll buy hopefully. They didn't have the logic practice board in stock so I am going to build a pcb that generates random data for about 3 protocols but the data will be within a range so I know I'm using it properly. Have you got a logic probe video? Classic rigol too...I had to get them to dropship me two new Analog probes as they discharged their guts when I compensated them. Worst probes I've ever used. The scope seems great through for the price. I wanted a keysight but I am not rich and wanted 4 channels. Even their edu line is obscenely priced for what you get. I have a 70mhz tektronix tds2002c I got on a trade though so I don't have gear envy. Haha Great content, keep it up. Hantek seem to have some high end gear on ali express like their bench meters and arbs.

[@simontay4851]

If i was buying a new waveform generator, i would definitely choose the DGE2070. I don't like that the uni-t has the BNC connectors on the side. Its a stupid design. You can't put other equipment next to it without the cables getting in the way. The power and USB on the back of the DGE2070 doesn't matter. You can get angled USB B to A cables and angled barrel plugs.

[@marksplace]

I canceled my Uni-T order and ordered the Owon after reading what you've said. You're 100% correct, It would be one thing if it were the only thing on your bench, it isn't though. Thanks for saving me from buying something that most likely would have regretted.

[@maebeans]

can the amplitude modulation be used to do if alignment in am radios?

[@graxxor]

do you have a more direct comparison with the UTG962E? as in which one is best for the price?

[@manreaper1238]

Thanks, I was looking for a video like this before it came out. As a result, between these two generators is it better to choose DGE2070?

[@KerryWongBlog]

If you need to store user generated arbitrary waveform, DGE2070 is the clear winner. But if you need the 75 Ohm output impedance you will have to chose the UNI-T as the DGE2070 only has 50 Ohm output. Otherwise these two AWGs are quite comparable (of course the maximum frequency DGE2070 generates is slightly higher).

[@stuartgartery2717]

Please see my earlier entry, it's possible to set any value.

[@Gengh13]

I could be wrong, but I'm pretty sure the 50 ohm and 75 ohm modes are just a mathematical compensation for the amplitude, the HW probably has a 50 ohm output.

[@alex-zu9zj]

HI What protection does it have against short circuit or overload?

[@scrook1027]

I just got one and they have revamped the innards. There are no large +/- voltage regulators no heat sinks on the IC's. I took some pix. if you are interested. I'm probably going to return this unit, as the output frequency stability / accuracy isn't very good even after leaving it on for an hour or so. I was hoping to replace my HP8640B with this. But it just isn't accurate enough for alignments.

[@CraigHollabaugh]

I'm interested in distortion in the audio band. At 1kHz sin, how far down is the 2nd and 3rd harmonic? Excellent performance and teardown video. Thanks

[@KerryWongBlog]

For signals under 1MHz, the harmonic distortion is spec'd at < -65 dBc, which is pretty decent.

[@CraigHollabaugh]

​@@KerryWongBlog ok, I'm looking for more than 90dB. I have an old HP function generator that works for this but it's clunky to operate, no knobs. Thanks for the fast response, the price point for this AFG is attractive, I'm looking up those clone DACs now.

[@anonymus8760]

@@CraigHollabaugh these cheaper AFG are usually 14 bit, which won't be near audio spec. For audio you'll be better off using a computer and USB audio card. Decent ones work well even on the higher sample rates such as 192kHz.(giving you about up to 90khz measuring range while staying at 24 or even 32 bit)

[@stefanlucianschnaider4633]

hello, I want to ask something. I need a square wave generator to test audio amplifiers up to 100khz. I see that when using the square wave function the generator has some ringing because the rise/fall time is too small and can`t be modified. Can I use the pulse function instead to generate square waves and also adjust for higher rise/fall time that the generator doesn`t overshoot the waveform? I want t go the cheapest possible. What would you recommend for my app between the owon dge2035 and the unit utg932e?

[@stuartgartery2717]

Maybe you have resolved the 50/75 problem. Go to Utility-CH1/CH2 Set, change from HighZ to 50 ohm, then either use rotary or numeric to change to any value.

[@dilumwickramarachchi5447]

Please Review the hantek TO1112D

[@jdmccorful]

I know it's "pie in the sky", but wish it were rated 150Mh. Nice work, enjoyed the review and teardown.

[@rokiedecentra9656]

i prefer how waveforms are selected on this, I bought a Hantek HDG3012 and on that you cant even see the waveform before you select it which is very annoying as it has many waveforms stored in it. You have to go by the name.... After you select a waveform it will bring you to the Waveform settings so you cant even scroll through them you have to press many buttons to change it again and again....

[@mikeb6185]

@KerryWongBlog The bodge wire is a bit worrying! I have looked at mine (DGE2070) - serial number 23040001 and it also has the bodge wire! It also has the heatsink misplaced just like yours. Clearly it's not just an issue on your unit! Should we be worried that the white 'goo' sprayed over components will not deteriorate over time and cause issues down the line? I have also noticed that after a short while - the unit does heat up considerably - I would be interested to know if your unit does the same? Maybe you can get a thermal camera and test? 🙂 The UK version comes with two USB power plugs - a european 2-pin USB power plug rated at 3000mAh, and also a small UK 3-pin plug power plug which is only rated at 2000mAh. This this gets really hot after a short while as the unit needs up to 3000mAh. I think i may have to buy another power supply plug rated at min 3000mAh, but this is not something I expect to have to do after spending £200 on the unit! With these issues I am concerned that the unit may fail prematurely - should I return and wait for a revised PCB? I would be interested in your thoughts!

[@KerryWongBlog]

I have been using it quite extensively for the past three four months. It did run a bit warm but it has been pretty reliable so far.

[@choosers5177]

Whats the max voltage?

[@StrongOneX]

Something went wrong in audio mixing, suddenly you're all up in my ear then afterwards far away

[@cambridgemart2075]

Up until 2:30 the sound is only on the left channel, then it's shifting between stereo and then left channel only again. It's difficult to listen to using headphones.

[@KerryWongBlog]

Sorry about that. There was some issue with my microphone unfortunately I didn't notice until a few minutes in.

[@jstro-hobbytech]

I'm not a big fan of owons form factor with that box. It looks cheap and I had an owon multimeter that I paid over 100 for and it's acquisition rate was slow. Even with probemasters. I will give it credit for having thr best display of all my handheld meters at the time.

[@pchunter168]

🙂

[@James_Bowie]

Very sloppy QC. You'd think that Banggood would take the back off and check what they are sending for a review. Motto: If it doesn't go bang, that's good!

[@stevenbliss989]

What a MESSY generator when changing frequency!!!!!!!!!!!!!!!!!!!!
