The halved sample rate when switching the trigger to another channel in single channel mode makes sense to me. It has then to sample the second channel. This would be the same like switching a additional channel on.

Was about to order a DS1054Z when I stumbled on your review. Now a DHO804 arrives tomorrow. Great form factor and plenty of features for a hobbyist. Thanks for the detailed review.

[peterlaidlaw]

Rigol owes you big ! I just bought one on the basis of your review and enthusiasm. For sure; Its a fine piece of equipment. Thanks for the excellent fun and honest review.

[PrincipalAudio]

I'm still blown away by the new scope. I mean, I was tempted by 10-bit scopes I'd seen in the meantime, but much higher price and less capability. Now this exists! Game changer. I'm sure the whole market is going to be totally rearranged very soon. No way it'll all stay the same. Competition is awesome!

[button-puncher]

These scopes really need a second monitor output, not just a mirrored output.
Then you could have your stats and math windows on the other monitor. That 7" display is just too small for it's capabilities.
Dave, thanks for the excellent video. Even though I've got a 1054Z, I REALLY want one of these.

[Dave-bpju]

Regarding the beige vs black colours... My wife and me are both engineers and have our "command centre" space (desks, computers, boards, etc., including small electronics workshop space) in our living room. That makes it a part of the decoration of the living room - since we are engineers, stuff like computers, screens, boards, soldering stations - are nice and fun decoration (assuming there is no mess), BUT my wife always has one condition: stuff needs to be BLACK to look nice with wooden desks. Screens - black. PC cases - black. Soldering station - black. Oh, you want to buy a scope and keep it in the living room? Great idea! But you know the drill - do they have black ones?

[PhillipRhodes]

Hey Dave, one thing you didn't go into much that would be interesting is the LXI / Ethernet functionality. And beyond the stuff specific to this scope, not sure if you've done a video specifically on LXI or not, but that's something I'd love to see. A (somewhat?) comprehensive look at all the things you can do with LXI, controlling the scope, or pulling data off the scope, over the network.

[DragonLord]

That is seriously impressive.

Even as someone who wouldn't have much use for a scope beyond simple power quality analysis, I'm incredibly tempted to get the DHO924S (the fully-loaded model).

[graemebrowne]

Thankyou for great tutorials, reviews and chat.

I am going into retirement and hoping to get back into electronics. In the process I will pension off my BWD scope and either replace it with a Rigol dho814 or the Siglent equiv.

[touchdepp]

5:11 Why can you still buy the old ones? You answered that in one of your videos. IIRC: It's expected by customers to get spare parts and replacement of the exact model that is installed somewhere so that they don't get different measurements and don't need to change procedures. Also IIRC: only good companies would provide that long term support and that would be a reason for a higher price.

A few times times in my life I was considering 1054Z (as my first scope), and if there was a significant sale for them, I might have picked one up.
But I'm glad I didn't, and instead, just ordered DHO804. Given my personal use needs, it will probably last me a lifetime (modified, of course).
Thanks for the detailed review and teardown, they really helped me make the choice.

[SaeligCoInc]

Incredible value for 12-bit scope! Groundbreaking at $299!!! Thanks for another great review!

[lolilollolilol]

It's remarkable that both the hardware AND the software are high quality in this unit. This is some serious engineering at an astonishingly low price. Rigol shot out of the park here.

[SirMo]

The main complaint I have about this new scope is the lack of 50 Ohm termination (which is really handy to be able to do in the scope itself, without having to muck with a physical adapter). But other than that, it's really incredible how capable it is. The fact that you can run it from a USB-C power bank is a killer feature as well. Rigol has changed the game with this one. What a time to be getting into electronics. You even get a quite usable FFT function. Crazy stuff.

[jasonbrindamour]

I had an old ring fluorescent light with magnifying glass. I got rid of the glass and added extended bolts where the springs were so I could add another set of springs from another junk one. It added quite a bit of weight capability to it. In any case I could totally mount that to one of those and you could just grab your scope out of the air and move it in your face and then back out of the way! I used it for moving around an old flouro tube 17" display and it supported it just great. I had to make my own aluminum Vesa converter mount but that didn't add much weight.

Dave, after you did your review, I bought this DS1054Z a few years ago. I still use with an upgrade to 100MHz and I am very satisfied. At that time it was number one in price. I won't be looking for a new oscilloscope for a long time. But it's good to know that Rigol is still releasing something interesting.

[aphantasiagreyman]

Now if they would only give us affordable spectrum analyzers and RF generators.

[robertjung]

got a 1054Z 8 years ago, still going strong... but seriously considering the DHO804, the 12bit + vesa mount + HDMI out + mouse input pretty much sold me.

[SimonCoates]

Dave, I wonder how many RIGOL DS1054Z scope purchases you are responsible for with that iconic review video. I'll start the count off with 1 (me 😀)

[jefflabute]

I've used Picoscopes for quite a while since the USB interface and intuitive software makes waveform storage and documentation easy. The DHO800 has all the features I use at a lower cost which includes serial decoding. Hmm, worth looking at.
