Looks Ok but a VESA mount compatible format would make it better. I've no idea about this brands history of firmware updates and quality as that can make or break modern computer based scopes.

This is what I get when I search for UPO1204 on the US site.

XY scope testing. Most digital scopes are horrible in this mode.

TEK CRT Analog scope

 

Hi,
I have a Tektronics TDA220 Oscilloscope, and it's ok, but it's about time, I bought an upgrade.
Are there any suggestions for a more up to date Oscilloscope please?
400mHz +. Mid range price.

Cheapest way to get near your 400 MHz desired capability is 350 MHz SDS2352X-E but only 2ch. ~$850
Edit to add:
I have tested this model ^^^ to return a -3dB point of ~400 MHz.
/Edit

OTOH SDS2104X Plus, the 100 MHz model has a tested -3dB BW of ~185 MHz but a big leap in display size to 10" touch and mouse capable although you don't require either to use it. These are a 500 MHz platform and deep homework will reveal ways to improve the low BW models. ~$1400

 

Just an old school lamp cord to a light fixture. No need to move your butt to turn on/off the lights while working or sleeping in the chair.

Snap.

I installed one of those pull lights too, like you we had them in our house when I was a kid!
