content: My old Tektronix died. I used to download oscilloscope images to my old Win 10 lab laptop using an ethernet crossover cable. A few years ago I did that with Internet Explorer. More recently that is unavailable and I used an old version of Firefox. But anyway that oscilloscope seems to be dead for now and I received the Rigol today.I have successfully downloaded scope face images using the crossover cable and this much newer Win11 laptop. But...the same web page that works on this newer computer gives me "This site can't be reached" when I try to connect using my old Win10 lab computer.I will bet there is some simple setting that can fix this but dang if I can figure out what that might be.I have tried ipconfig /flushdns but that did not fix the problem.Does anyone have any ideas? When it comes to power converter design, I have many years of experience under my belt. But when it comes to most IT matters, I am mostly just a dumb user.Another route might be a USB connection. But the Rigol documentation does not tell me whether that will allow me to transfer waveform images to the computer. The documentation seems to get into programming and does not get into a lot of specifics.BTW I e-mailed their help a few days ago.....I did not even have the unit yet. No response yet.I will say that the Rigol oscilloscope appears to be very capable and makes the old TDS3034B "Barbie Scope" look like a big horse. But I have to do a lot of figuring it out.Thanks

content: Not sure which Rigol Model you have.For some oscilloscopes you can download the UltraScope software which should do everything you want to do, plus in some cases control the oscilloscope from the computer. I've done this via network and also via USB in the past. I think the older units had a similar software with a different name, also downloadable from Rigol.

content: ThanksI have the DHO924S. I installed the "Ultra Sigma" software on both computers. That should provide connectivity via USB and maybe also by other means. But as I said I am unclear as to what I can do with it.I will see what I can do with that tomorrow. But I am irked by the fact that I have already done what I wanted which is to download a few screen images using the crossover cable on this computer. The older one just will not "go there."

content: The other alternative is to just plug a USB stick into the front panel USB port and capture your screen to that - that's how I've ended up doing it more consistently across a wide variety of modern instruments. Most will allow you to capture a JPG or similar of the screen and store it on a USB stick. Then you can put that USB stick in any computer that has a USB port and read the screen off of it.If you do want to do this via the network, you'll want to figure out the IP address which has been assigned to the oscilloscope. It should be visible somewhere in a menu somewhere or via ultra sigma. Once you have that IP address (like 192.168.1.123) you should (in theory) just be able to stick that IP address in a web browser on your Windows 10 PC.

content: Regarding the USB to computer interface:I have a case of "RDMS" = "Read the Manual, Stupid!!" It says:Connect the instrument to the PC via this interface. Then you can use the PC software to send the SCPI commands or use the user-defined programming to control the instrumentI suppose it does NOT say that you CANNOT upload (or is it download?) the display image to a computer via USB. But I would like to think that if it could do that, they would say so.I was going to say that I therefore have no use for this interface, but:I saw one review complaint that the oscilloscope does not remember its settings from the previous session. If that is the case, there may be value in being able to save and retrieve those settings. But this thing runs on Android OS and seems to have an amazing amount of intelligence as compared to the 20 year old Tektronix. Remembering the settings seems like pretty basic functionality.

content: I connect my rigol scopes to my network via Ethernet, like any other device, with the scope just set to use DHCP and my router set to always give the scope's MAC the same IP address.From that, I just use scripts that send scpi commands via tcp. I even put some up on GitHub:https://github.com/djacobow/ds1000_ds2000_cmdlineThose particular scripts let me to just about anything I'd ever want to do, including screen cap, with the scope for the two units I own: a ds2072 and a ds1054. A lot of commands might work differently for the dho924, but I suspect the screenshot would work.
