Ah, I understand. But version 01.02.00.01 didn’t seem to show up anywhere

Somebody on this forum mentioned about 01.02.x disappearance some time ago. Also there was discussion about bugs in this particular update.

No new info to anyone here, but it looks like they sent Voltlog a free unit which is nice:

Is the 800HD ?
What's new in it?

Read what I wrote, a second time and slower.

This is a standard DHO814

Little bit of a pain to download, usually all my instruments need is a disk with everything extracted on it and it finds the file. It didn't work until I selected the GEL file from the extraction.

What zoom do you mean? When I turn it on, the scales of all channels are restored, and if the horizontal zoom was turned on, then it remains on after turning on the oscilloscope.

The setting for what happens when you push the horizontal timebase knob.

Ah, I understand. Yes, this setting is not saved for me either.

I don't think it's "new". At least nothing new since Jan 11 2024.
it's the same version 00.01.02.00.02 I downloaded already, and my download release notes say

Mixing up dates by just a few weeks is spot-on for Rigol. I have downloaded firmware for other Rigol scopes where the release dates stated on the website were off by months, and in either direction, from what was inside the .zip archive.

For whatever reason their firmware release process is messy, regarding dates as well as the version numbering scheme.

[AndyBig]

Yes, this is the same version that appeared on the Chinese site a few days ago. Now they have made it available on the international version of the site.
But European and North American sites are in no hurry to post it yet.

It's just that they wrote above that there is no new site anywhere except the Chinese site. I threw the link where else I found it.

I did try link, the download button pops up a new URL and wants a login. I even tried to register, but it keeps saying the captcha response is wrong, but I don't think my input is wrong, unless I need to somehome input a curvy line too.

I thought I was buying a properly working scope, free from bad bugs. Not sure my assumption was correct. Bugs, and very hard to understand FW releases, or even ability get FW versions easily, makes "rigol" a "think twice" brand. But of course, I don't own 1000+ series anything, so not sure if the same headaches carry over to the more expensive products?

[Robaroni]

Randy,
I had the same problem, finally I refreshed the site and it worked. I think what might happen is if you get the captcha the site gets goofy or goofier?

There were warnings. Rigol did worse than usual here. Others do better job, even Rigol used to do better than this..
Let's hope they get a grip soon.

As was suggested, maybe try refreshing (and a hard refresh, like Ctrl-R or Ctrl-F5, depending on browser). I sometimes run across failed captchas because of a stale cached captcha image. Sometimes it seems like 2 captchas are sent, with the first one displayed while the second one is what the server expects a response to. Refreshing will usually sync things back up.

I have a DHO1074, upgraded to DHO1204 with memory depth upgrade. It's not bug free either, and I believe shares some of the same bugs, though from what I'm reading it seems to be a bit more stable than the DHO800/900 series. Of course it's been out a year longer, but as they're so similar I'd expect much of the DHO1000 firmware to be present in its little brothers. Navigating Rigol's various sites and finding firmware is not really any different between the models, though. That's just Rigol being Rigol.

For the price (famous last words!), I'll live with the quirks. I've returned Siglent instruments for bugs but this is just my back up scope and I don't own anything else from them.

Yep. It works for me. Would be nice if they fixed a couple of things but it gets the job done as-is.

Could it be better? Of course. ANYTHING can be better.

I don't even care if the FFT doesn't have every possible parameter, it's plenty good enough to see frequency peaks and harmonics when I need them (and really easy to use - just swipe and pinch to find them).

And maybe I'm getting older but I'm a huge fan of the text readability and overall display quality. I'm not seeing that on any of the images of the new Siglents.

Plus the new Siglents are huge - as big as the previous generation where the Rigol is small/cute.

[Martin72]

where the Rigol is small/cute.

Toys should be cute so that children enjoy playing with them.

In fact, a fridge is nothing compared to that.

I bought a Siglent electronic load, it was riddled with bugs and the fit and finish was horrible. I sent it back and bought an Instek which is very good but it cost more. You get what you pay for I guess, I'm used to Keysight, Tek and other better brands. It's a tool, I don't want too many work arounds or I dump it.

I honestly don't think the DHO800/900's are that bad and I like the footprint, if it was a bigger scope I wouldn't have bought it. The fit and finish is pretty good too.

I still wondering why small scopes like 800/900 even come with a screen. Just make the scope-smarts, have two USB-A ports, bundle it with wifi nano and a wireless logitech keyboard/mouse, and just tell buyer they need to supply their own monitor with HDMI connection. Buyer can then opt to use a small 8" display, or crank it up to a large 32" 4k, or even a 15" touchscreen.

I have a handful of good monitors I don't currently use, and I will eventually attach one to my 804, but then why do I need the 7" on the 804?
The cpacitive touchscreens emit their own EMI / noise, so not having it just mm away from your scope inputs and scope electronics is probably better.

If there was a no-screen option of the 804, I would have bought that.

[Martin72]

They are not, you can work with them for the money and they are low-noise.
Not a bad choice as a second scope for the desk.

All displays emit noise !
Go sniffing for it with sensitive gear and you will find it.
LED lighting is worse. 

Never an issue with correct probing techniques.
