OWON HDS 200 Handheld Oscilloscope w/ builtin DMM/AWG

[agaelema]

Thanks for the answers, but I was thinking about one thing and asked another...

Does the DMM perform RMS AC+DC measurements or just AC?

AC only. In DC mode the AC components are averaged.

How do we get the latest firmware, to get the new features and bug fixes? Owon has firmware downloads for some products, but not this one.

Alternately, is there any way to dump the firmware from one scope, to upgrade another?

Send an email and ask for it. You can find their email address here: https://www.owon.com.hk/products_owon_hds200_series_digital_oscilloscope

A firmware version is only compatible with a serial number range, so you need to supply that.
My scope was bought before summer, shipped with version 1.6.0 and the newest supported firmware is 1.7.0, even though they now ship version 4.x.

It's a bit crappy of them I think.

I found a bug in my hds242 (ver. 4.1.0) - measurments on ch.2 not working, simply showing in state OFF, have anybody noticed same thing?

[dixvgd]

I figured out how to make it to work, thank you.
Great scope for it price, but I hope there is potential way to upgrade it to 72MHz version and add circuits to enable afg.

Looks like 40 and 70 MHz is the same (analog bw looks higher than 40 MHz on HDS242), just different probes bundled. But not sure.
And separate AFG is more handy for me and they generally more cabable. Also parcels to Ukraine for more than 100 EUR are imposed by custom taxes so basic model is more interesting in per dollar performance.

Have anyone of you had any success contacting them about firmware upgrade?
I wrote them an e-mail 8 days ago and also wrote through their web page after 3-4 days of my e-mail, still no response at all...

Several have, including me. It's a bit of a hit and miss.

I got a firmware update, in my second attempt at contacting Owon. It took a week, with a reply after a few days asking me some questions like serial number.

Received my HDS272S yesterday. Firmware version is: V4.2.0
Im really impressed with it for a handheld device.

I have sent them all the information needed at once.
However, yesterday they have replied me...

They told me my unit is the latest one, no need to be upgraded...
...then I have told I read about 4.1.0 which they replied that is because of the lack of some parts like LCD screen and they needed to replace some parts and that is why they needed a new firmware release...

I don't know how far it is true and its relation of BS but sounds interesting...

Also I really hope if they had to use other components, then they did it in a way what preserves hardware compatibility - it can be done if the firmware is not junk.
I doubt the only change is for a different LCD or other component(s)...

[simba15]

Seems like a great meter.

Anyone tried to hack it from 40mhz to 70?

Anyway to add more waveform storage? or math functions?

New hardware version of HDS272, HDS200 PCB MAIN V3.0 (2021-09-27) and firmware v5.1.1.

I wonder why there are so many PCB versions, I just checked mine and it's V2.20 (2021-09-09) Which is only a couple of weeks difference!

I tried to swap LCDs between pcb 1.0 (fw 1.8.0) and 2.1 (fw 4.1.0) scopes, resulted in shifted images in both, one right-down, another left-up, so it's displays was different and not 100% compatible, pcbs are different too, so maybe reason is not only LCD's difference.

No need to BW hack, my HDS242 has resulting rise time not more than 5ns (include generator on SN74HC14 with 5-outs-in-parallel has about 2-3ns) which is 70MHz+ BW, just use proper probes.

[TheBay]

Do all the software versions have the annoying "Quirk" where if you use "Auto" it will sometimes end up on CH2 even though CH2 is off? I'm getting fed up of going back in the CH menu to select CH1 again when I want to adjust the timebase etc.

[simba15]

Any one seen and good BF/CM deals on the HDS242S?

Best I can find is ~ $129 with coupons for the HDS242s (was about $125 on 11.11)

TIA

Hi, so I just got my Multicomp MP720781 from Farnell, which seems to be just a rebranded HDS242S with green rubber instead of blue.

If anyone is interested, my unit came with V2.0 (2021-03-24) main PCB and V3.0.0 firmware (they don't seem to sell trough a lot of these)

Hi, tunk.

thx your reply.

The video mentions high refresh rates and not being able to see the modulated waveform clearly:

HDS272S already  supported Low Refresh(My machine version is V5.3.0). Let's see how to set:

I use mainly slow refresh mode because without intensity grading fast refresh in most cases is useless IMO.

[BetterAndBetter]

I can't agree more, Intensity grading is improtant when in fast refresh mode.  but this model is difficult to implement due to resource limited.

OWON have a new model HDS2102S on 100MHz
