Hello,
Does anybody know if SCPI commands support multimeter functions? Manual is silent about this.

[steelz75]

Nice to meet you.
We have received the HDS272S V.5.7.1 firmware from OWON and will provide it.
It is compressed with zip.
Have a good HDS200 life!

My Device : HDS272S
Serial : 2148***
Hardware ver. : Unknown
Old Firmware ver. : V.5.3.0

I've a HDS242S with V.5.3.0 firmware! Can I use this update for my OSC?

[steelz75]

Nobody? Really? Come on guys, give me some advice

Nobody? Really? Come on guys, give me some advice

I believe if you read earlier in this thread, you'll see a post where somebody tried loading 272 software onto a 242 meter and bricked it. I'd advise contacting Owon directly.

Hello,

Good question! The SCPI doc has commands for the Osc and AWG modes, but not multimeter. I guess you could try running some of the typical multimeter commands and see if you get results back? Shouldn't hurt anything to send the request if it's not supported.

I had seen the discussion but I didn't find it anymore ... thanks for the advice 

[BILLPOD]

Good Morning, My problem is not the software/firmware inside the scope, but the computer interface software that I downloaded from the Owon site.   The Zip file won't unzip.  I'm using a Windows 10 computer.   If anyone's had this issue I would appreciate the solution to this problem.  Thanks in advance.
    UPDATE: discovered the download I get from the first Owon site was 'blank'....nothing in it....DUHHHH.  I went to their
'Official' download site and got a good one.   So now I have an o-scope screen, but can't get a waveform on it.   More experimenting, I guess.

That's funny because I just ordered a 272S because I can't get my old Hantek DSO and AWG to work because of unfixable(?) driver certification issues. They used to work on my Win8.1 machine. Anyway, never again Hantek! I also want to replace my TPI Scopemeter 440.  And I have an HP 1740 (the one that Dave slaved over). FFT would be nice, though.  I paid $240Cdn at Banggood.

I believe that is the mantra of Hantek owners around the world.  "Never Again Hantek!"  or NAH for short.  NAH!

I recently picked up a HDS 242 (S#2129XXX, Board 3-21-21 V2.0, Firmware V3.2.1) and upgraded the firmware to V3.3.3.  Are there any differences in the performance/accuracy between the different versions of the board? 

[rad400]

Having problems with Owon HDS242 scope portion.  I inputed a pure 12v RMS sine wave and got readings on the scope of 34Vpp and a mean reading of 67mv.  The 67mv is the problem.  If I did my math correctly, with a meter input of 12Vrms, the scope should be reading around 10.8Vav, but it only reads 67mv.

I have updated the firmware to the latest for my meter of V3.3.3.

Anyone else having this issue?

Thanks

[tly]

The 67mv is the problem. 

The mean value of a sine wave is 0; but due to sampling it will never be exactly 0.
Do this test: set a sine signal with 1Vpp + 1V offset.
The mean value displayed should be around the offset value 1V +/- something.

Edit:
Use Peak-2-Peak measurement and convert the measured value to RMS

I dug this out the other day as I needed to use a handheld scope for something.
Did the CH2 issue ever get resolved on any firmware versions?

If I ever use Auto on mine it will always default to CH2 for controls even though there is nothing connected to CH2, makes it a real PITA to adjust the timebase for CH1 as I have to keep manually selecting CH1. Or I get the annoying message "Channel 2 is Off"

Mine is:
PCB V2.20
Firmware: V4.2.0

From all that I've read to this point, there hasn't been a fix for a firmware version that would run on the V2.20 PCB. It has supposedly been fixed as some point for the firmware for later board models. I also understand you could brick the unit if you try to load firmware not made for that board version.

The workaround that I used was to simply hit the AUTO button a second time to toggle the "focus" back to channel-1 (see exception below).

Note that the scope mode has four different display modes (for lack of a better way to put it), and each of those modes will dictate what the blue arrow keys and the "F" keys do.
They are: CH1/2, HOR, Trig, Measure/Range. Each of these modes will highlight their respective function on the screen.

I found that the toggle to CH2 when hitting the AUTO button ONLY happens when the screen indicates that it's in the CH1/2 mode. In all other modes, it works as it should.
Looking at the screen highlights prior to pressing the AUTO button makes it a little less frustrating because you'll know what to expect and whether to hit the AUTO button a second time.

Hello everyone,
I'd like to update the firmware on my OWON HDS272S HW v2.0 FW v3.1.0 serial number 2124xxx. I "think" it should be safe to update to fw v3.3.3 that @tly uploaded, but I'd feel a lot better if anyone who has done so could confirm it worked for them 

While reading this thread and trying to figure out what is the right firmware for my board revision I compiled all the info I found in a document I am sharing below, I have also collected all the uploaded firmware files and images of hardware revisions.

Unfortunately the attachment upload limits don't allow me to upload the whole packed folder here (not even just all the compressed fw files) so I am sharing it on Google Drive here https://drive.google.com/drive/folders/1lULgGCX0rwCR3fdHBU8-bwArSPSJaWcp?usp=sharing and here is a GitHub gist of the Info Doc https://gist.github.com/fuho/967396859a4f82346095c6abc941a328.

Here is a repository where I intend to store everything https://github.com/fuho/owon_hds200

I'd like to ask anyone who has received firmware from OWON to post it here with details like board revision, board date, fw updating from, the first 4 digits of SN or any info that could help anyone else in figuring out how to upgrade without bricking their device really. Feel free to DM me if you prefer. I'll add it to the archive and update this post.

Right now for example we only have one FW for board revision 2.0 and none for 2.1 or 2.2. Thanks a lot if you decide to help

## Hardware

At some point flash chip changed from from "Gigadevice" to "Macronix".  The Gigadevice has a type of OTP SecureRom that
is read-only with a hard coded checksum. Those are apparently "NOT upgradable".

Hello everyone,
I'd like to update the firmware on my OWON HDS272S HW v2.0 FW v3.1.0 serial number 2124xxx. I "think" it should be safe to update to fw v3.3.3 that @tly uploaded, but I'd feel a lot better if anyone who has done so could confirm it worked for them 

I updated to v 3.3.3 my unit (FW 3.1.0, sn:2124xxx) without any problem!
I got this FW directly from OWON (after many unsuccessful preliminary requests...).

So: upgrade without worrying!

[wenesga]

I have this version

Anyone tried to hack it from 40mhz to 70?

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.

So if I use a 100mhz probe on an HDS272S (70mhz), will I be able to use it as an HDS2102S (100mhz)?

No, BW is determined by the input stages of the scope not the probes.

@ExaLab posted same question.
Send him a PM and ask if he solved or not.
and some info that I noted:...

Hello everyone,
I'd like to update the firmware on my OWON HDS272S HW v2.0 FW v3.1.0 serial number 2124xxx. I "think" it should be safe to update to fw v3.3.3 that @tly uploaded, but I'd feel a lot better if anyone who has done so could confirm it worked for them 

I updated to v 3.3.3 my unit (FW 3.1.0, sn:2124xxx) without any problem!
I got this FW directly from OWON (after many unsuccessful preliminary requests...).

So: upgrade without worrying!

I have this version

Anybody knows what software can be used to control this scope via SCPI?
I tried looking for anything, and most of the stuff is for serial interface, but this scope is using raw libusb-win32 driver
