Did the scope come with VESA mount points or did you modify the scope for it?
It came with the mount point nutsert's but if the VESA mounting plate is flush it blocks the fan cooling air intake, so standoffs are recommended.

Had CAN from day 1.
I2C, SPI, UART, CAN, and LIN, all standard
It's only basic CAN on the 1202X-E, which is great, but no CAN-FD (a extra cost option on the SDS2000XP series and standard on a PicoScope USB), that's not so great. So I'm using a $10 logic analyzer instead or the 2 Series TEK.

It's seen better days but still works.

A few screen saves to thumb-drive.

It auto-updates the time from a NTP server when it boots if the LAN is connected. Can't find an option screen to set the internal data and time manually.

Lxi-gui gives the live screen view of the Siglent on the Linux system and control via SCPI commands.

Congrats @nsaspook looks great. I just picked up the MSO5074 and haven’t had a chance to unlock to 350 MHz yet. I saw the DHO800/900/1000 12 bit scopes and can’t decide which to get.
There’s a hack to unlock all features which I’m sure you’re aware of. Looks like a great little desktop scope for work. I might add a battery option to it.

I am enjoying this thread, kinda resembles another one I have elsewhere. I'm always up for learning new things. These scopes are really neat.

They are neat because they are scopes with generalized modern computer OS facilities for I/O and networking (HDMI, mice, touchscreen, remote network display VNC type control). I wouldn't recommend it for field industrial use but it fits in the home hobby niche nicely. it's very usable now but the next major firmware release (there should be one) will IMO be a make or break event for the scopes long term appeal if it fixes some of the minor HID glitches and adds functionality like CANBUS-FD decoding.

What do you think of the screen size when used without the external HDMI? Is it legible? I'm concerned that a 7" screen is basically a large phone screen and might be too small to see especially for those of us needing reading glasses. Also is 1.00.00 software a deal breaker? I just like the 12B resolution and think this would be great to have at my desk so I don't have to go to the lab to fire up the big Tek.

The screen size is fine and very clear HD (I'm near-sighted with glasses) for what you pay for at a reading distance between 1 to 2 feet. I have a $90 BB monitor (that I also use on the ELMO doc reader), so it's nothing fancy. The 1.0 firmware is fine, it all works but needs refinement.

Testing the HDO814 trigger output to lock the scopes with the EXT input of the SDS 1202X-E in a 3 node CAN network. The trigger source for both scopes is the canbus transmit frame on channel 1 of the 814 from the data collector for two remotes. The video looks at trace GPIO signals from the LCD SPI DMA driver start and completion for timing adjustments. As expected, the remote unit displays show timing drift on channel 4 (3 CPU main lop processing trace) on the 814 compared to the master display trace on channel 2 (1 cpu main loop processing trace) on the 1202X-E.

It's nice having them all work together as a system.

XY demo connected to L/R audio outputs using the Linux Audacious media player. bad_apple.flac
https://github.com/yeonzi/badappe_oscilloscope/releases

I didn't adjust the advanced X/Y options too much so it's possible for it to look better (slow refresh rate at that sweep setting) but a pretty good job one the fake CRT green painting.

TEK CRT Analog scope
