No, but I think eventually I will need a video output to capture, so I think PC based is a good solution.

james_s:
It should be simple enough to implement a video output on that project I posted, it has a display.

xmo:
The Tektronix DSA series could display up to 8 concurrent traces in color on either a single graticule or a split screen with two graticules.

The traces can be 'live' views, memory traces, math derived traces, or FFT traces from up to 12 input channels

Attached are images showing two screen captures and a digital camera view of the screen.

Fungus:
Maybe 4 'scopes with HDMI output and some sort of HDMI capture on a PC. I'm not sure what the cheapest 'scope with HDMI output is, maybe a Micsig.

Or ...  maybe 4 cheap 'scopes with remote web interface, eg. Siglent SDS1202X-E. I don't know what the refresh rate will be like though.

I quickly checked Digilent WaveForms with a demo Analog Discovery Pro (ADP3450), and it seems like it does most or all of the things I ask. Any number of XY views possible, the source for X and Y axis can be selected freely from available channels.

It only has 6 input channels though and buying two of them to get 4 displays ain't cheap.

I decided to give PicoScope (4424A) a try.

Using multiple scopes is an option but it will consume too much space, so it is not my first choice.

About ADP3450, it has 4 channels and they can be freely assigned to any XY view as much as I can see. This I think is also a good option but I already have a Digital Discovery, so to see something different, I decided to check PicoScope first.
