Who needs trust when the stuff is so cheap it's disposable?
All it has to do is work for 3 years, have half decent performance and reasonably good industrial design.

The whole world needs trust and reliability. Countries such as France are coming to realize the perils of manufacturing cheap and disposable stuff.

That, in a nutshell is the problem. Buying cheap junk.

I've been burned far too many times buying cheap junk. A 600W power supply that's really only halfway reliable at 300W continuous VS a well known name brand (like TDK-Lambda) 600W supply you could run at 650W continuous from now until the equipments doomsday.

 

Their trust in you or yours in them ?

After Siglent offered us NZ distributor in 2013 I can honestly say they give us all the support one could ask for.
Product reliability/warranty is near 100% and any problems or parts required are quickly delivered.
Supply chain is wonderful and when needed we can get stuff we don't normally stock in just 1 week.

Not having run a small company before 2013 their support and comms are excellent.
Do we see this from the majority of western suppliers ?

You guys are selling to a no BS, technically savvy base yet you still try to pull BS like the serial decoding non-fix message about a regression from a firmware update. Small support issues like that degrade trust when you try to BS engineering.

Setting up a new maintenance shop so time to buy new toys.

 

The DHO series are nice scopes but are lacking in advanced signal decode options, even at extra cost. I've looked at the various options but I can't even find CAN XL as a decoding options even on the higher end budget scopes.

Happy with the acquisition at this price range, but the UI must be enhanced, fortunately some changes can be made by the user itself.

On eevblog there's a bunch of chatter for custom UI by "hacking" the Android scope package. There's been a lot of great enhancements by a few users there.

 

Rigol DHO800/900 new firmware v00.01.04.00.02 2024/11/1

https://int.rigol.com/products/detail/DHO800

YMMV. So far so good on my unhacked scope.

 

Now there is a new model, the DHO824 with 200MHz bandwidth, upgrading an 804 or 814 to 824 is very easy.

Before you could do the 200MHz hack but now there is an official model for it with a much easier model ID edit.

 

Wow, Rigol downloads are beyond bizarre.
The link is to a 1.03.00.06 zip, yet it downloads the 1.04 FW, and in the Release Notes text file it makes no mention of a 1.03.00.06 FW.

From what I know, they fixed the bad bugs they recently introduced (XY bricking), but no mention of fixing the FFT that's been an issue for years.

The UI can be changed:

Users of the 800-900 have been wanting to tweak the colors of the traces. Not sure is any of the custom user FW installs have managed to do that yet. Adding a color wheel to set a color would be nice.

 

Got a good laugh from this one. I added a extra remote display on my Solar monitoring system via the CANFD 4-wire network (two differential signal wires and two power wires). It's a tee from the other remote display with no termination resistor (R10) on the end of the second remote with a several meter cable run for the extra display.


The DHO does CAN but not CANFD decoding (FD has two bit rates, nominal 1MHz and data 5MHz on this).

Set the DHO decoder to 1MHz bit rate to see the ID header, when it switched to 5MHz for data, this is the scope display try to decode that.


"Stuff"

The 5MHz signal section looks fine, with little ringing or reflections.

 

What version of firmware is on that DHO?

 

What version of firmware is on that DHO?

It's what they pushed out over the internet to the scopes upgrade function storage. I enabled the install of the new firmware and it works just fine.

It should be version: v00.01.04.00.02

RIGOL brochures show a model HDO824, 200 MHz but I can't find any mention of this elsewhere.

It's basically a pre-hacked DHO8x4 you can buy from the OEM so you have warranty coverage . There was a new firmware update for that model months ago.

 

I believe the 800-900 series all have the same limitations in bandwidth (250MHz), but the OEM license key for each model restricted stuff down. Many buy 814 and hack it to get max ability.
IMHO, all they needed to do was to sell the 800 as 2ch and 4ch version with all restrictions removed, and if you needed more features you buy a 900 2ch or 4ch. Rigol does some silly stuff with models.

 

MHO900 series mixed signal oscilloscope. For $999 entry level MHO934 you get 4CH 350MHz 12 bit at 4Gs/s BLING!!!

Santa might bring me one.

I thought I was only going to need audio and 3-30MHz ability, then 6Meter (50-55MHz) came along. Then 2Meter (144-148MHz) came along. Now, I just added 70 Centimeters (420-450 MHz) and 23 Centimeters (1240-1300 MHz) to my bench as well. And it doesn't stop there as all modes and licensees (except Novices) are authorized Amateur Bands above 10.5 GHz. I can't cover over 350MHz on my scope but can do 1.2GHz with an old Hewlett Packard signal generator and HP spectrum analyzer as well as my NanoVNA. I have no plans to expand on that... I do use the 2Meter and 70centimeter bands and have put up a 1.2GHz vertical antenna but no traffic on that band unless you go extraterrestrial satellite or moon bounce.

 

Are you really going to wait till Xmas?
