Rigol's New DHO800 Oscilloscope unbox & teardown

[Fungus]

What else needs to be done?

You also need to tell us what you typed in ADB (not just "it failed!")

The screenshot shows. Typed device search "./adb devices" typed in the terminal.

Ok, maybe you need a "connect" command...

This is my TP-Link WiFi adapter:


I'm very surprised it works - I couldn't find a slot to insert the CD in the Rigol!

Good to know  . I have one, for use with the Siglent SDS1104X-E. I will try it with DHO1074, it was shipped and will be delivered in 2-3 days.

I case you missed it: The best way to set up WiFi is to connect dongle+keyboard simultaneously (with a USB hub) and type Win+N to get to the Android setup.

The keyboard works to type in your WiFi password, too.

And implement the suggestion of TimFox and supply the rigol scope with a linear power supply (and see what happens in terms of noise on the reference signal for the probe alignment).

Not much...
The rigol supplied with a linear supply has not changed much regarding the ripple on "my" reference signal.
But at least I could look at the currents with a multimeter, the comparison with the usb powermeter will follow soon.

Voltage: 15.04V Current : 14mA (Scope in standby)
Voltage: 15.06V Current : 2.49A +/-60mA (Scope on)

Offset range seems to be much better than is specified in datasheet : +/-1V for (500uV/div - 65mV/div).

Knowing Rigol's history, there will be tons of bugs that takes years to fix. People get all exited about new equipment and then are super happy with every firmware release that fixes problems/bugs that should not have been there in the first place. ... I'm sceptical.

When do you estimate Siglent will get around to fixing their FFT? Dave saw some serious problems with it in his video.

See video at 32:17: https://youtu.be/S8jrpCoZyx8?t=1937

(and look at how slow the Siglent FFT is by comparison...    )

I believe the bigger question is when will Dave get to use DSO FFT correctly ?

Hello, Sir! Can you share of new firmware v00.01.02.00.00? It is no longer available on the rigol website.

[Martin72]

It is no longer available on the rigol website.

Now think about why...

[enson72]

Today, firmware 01.01 was also removed from the site ))

Still available from Rigol Europe, both on the Support and Shop sites:

Yes, but they cleaned up here. https://www.rigolna.com/products/rigol-digital-oscilloscopes/dho800/  I was there this morning

I have not seen any DHO800 firmware on Rigol's North American site for a few weeks, if I recall correctly. And their selection of firmware is pretty thin in general . In Europe, they have two separate repositories: The Support section seems to have the latest firmware only, but a complete set for all products. The online shop's product descriptions still offer a history of older versions for download (at least for some products -- just checked it for the DHO1000 series).

I don't know why it is so hard for Rigol to maintain one consistent repository (or one per region, if they have to, but keeping them consistent).

I don't know why it is so hard for Rigol to maintain one consistent repository (or one per region, if they have to, but keeping them consistent).

Looking at their scripting code, etc., it is not as if they are not capable of fixing this literally in minutes if they wanted to. This and other lack of elementary good release practices (like checking that firmware release notes are NOT encrypted for the MSO5000, etc.) is simply incomprehensible.

[ebastler]

Well, we don't know how independent the regional offices in the US and in Europe are -- and how competent...

I am one week and two emails into getting my 100 MPts option code, which was supposed to be included with my DHO1074, from the European office.

I am one week and two emails into getting my 100 MPts option code, which was supposed to be included with my DHO1074, from the European office. 

Same experience here.  I bought from Rigol EU but through their Amazon.co.uk. store.  Before purchase I asked them to confirm that the offer still included the memory option, given that it was now 40% cheaper than when originally listed.  They replied within 24 hours to say that it did and that either the unit would have the option license already installed, or the code would be in the box.  It wasn't.  I messaged again and they told me they'd send it to me within three working days.  Five working days later nothing.  My third message saw a license code sent to me within 1 hour of me sending it.

Not the best customer experience but my point being that someone does seem to be reading emails/messages and acting, albeit they need reminders.

FYI - the original firmware v0.01.00 zip package is pkg available from https://mall.rigol.com/item.html?item_id=1577
(the link is for the v0.01.00 pkg, but the text says v0.01.01)
Scroll to the bottom of the ad and click on the 6th tab over:


Or direct from:
https://mall.rigol.com/item-downfile.html?file=https%3A%2F%2Fsupportcn.rigol.com%2FPublic%2FUploads%2Fuploadfile%2Ffiles%2Fftp%2FFirmware%2FDHO800_DHO900%28Software%29UpdateV00.01.00.zip

The v0.01.01 pkg can be downloaded too if you edit the above link.  Trying v0.01.02 gets a dancing 404 robot.

[enson72]

Tell me in which application you open the stored DHO signal for analysis. I couldn't open it in any way. Or share the link, please. How to do it.

I searched but didn't find what this means in the 01.01 release notes :

"Remove all time-related displays on the instrument"

It means they don't show the date/time anywhere now. The time was wrong because there's no battery-backed clock in side these.

It syncs time when you connect it to a network so they could have done it better but I guess that's the minority of users, so...

I just posted in the Hacking thread some info on using NFS to store your wave forms, recordings or settings on a NAS box - in general using a USB drive is the simplest but if you have the scope connected using Wifi the USB will be taken and a hub would have to be used, or if the scope is connected full time using Ethernet - this method can reduce the write cycles on the built-in SD card - https://www.eevblog.com/forum/testgear/hacking-the-rigol-dho800900-scope/msg5228379/#msg5228379

The Utility icon on my DHO804 had an indicator on it this morning. (The scope is hooked up to wifi.) When I went into the Utility menu, it indicated that a firmware update was available. I clicked on an update button, and it installed version 01.01.02. It rebooted, and I validated that the new version was installed. The build date, per Utility->About, is 2023/11/09 17:35:40.

On the one hand I am pleased that the network update actually works (and that the "Utility/Update" menu entry is not just a misdirection for all who actually want to update via USB).

On the other hand, it makes me a bit nervous that oscilloscopes now also "phone home" to the manufacturer. That opens up new possibilities to detect or disable hacked licenses, if Rigol so desires. I think I will configure my firewall appropriately before connecting my new DHO1xx4 to the home network, and am happy to take the USB detour for firmware updates...

Let's see...

Mine doesn't.

People have been worrying about that for decades, Rigol hasn't done it yet...

(and won't, because it would be a sales disaster for them)

Maybe... As long as the scopes were not calling back home, Rigol had no way to detect "home-made" licenses. Now, with the central generation of all purchased licenses via rigol.com and with scopes reporting back to base, they can detect this.

Rigol would also have new ways of addressing users directly, "talking" to them via their scopes. They could e.g. set the invalid licenses back to "trial" status for a while and encourage users to buy a permanent license. Ah, brave new world...

Sure, we don't know whether Rigol will take this step. Compared to the MSO5000 hackability, DHO users are already kept on a much tighter leash. Maybe that's good enough for Rigol, maybe not. As former "this is expensive" differentiators like 12 bit ADC and 10" or larger screen get commoditized, they may look for new ways to charge extra money.

In any case, my scope will not be allowed to phone home, via suitable firewall settings. That should work for now -- until the next generation of scopes insists on an online connection to check the license status every fortnight...

Made me curious, just turned it on and...Bingo, same here.
Should I proceed..Ah, nevermind, I´ll take the risk...
More to come after this.
