What is it?

wow, the sync tips look a bit different from each other, text coding at the top of the frame ?

I thought "text" at one point but text would be more "rectangular" because its' digital.
Looks like regular old video to me.  But that video on the left shaped like triangle waves is
what is stumping me at the moment.  However, the after the triangles, it goes to a gray-scale
value it looks like since the successive "video" or whatever goes below that line.
The back-porch just before the sync-tips arer is where the color burst would be, I think.
EXCEPT that the color burst is on a front porch, not a back porch.  Maybe it's backwards ?

If I saw a color burst on a porch then I would say that the triangle wave and then the short piece of
gray might be a portion of a color bar reference during vertical interval but no burst and weirdly
placed porch stumps me !

Maybe it's from an old video game ?  TV oscilloscope ?

Is this waveform RS-170A compatible ?

They DO use a single frequency during the start of a line for a "run in clock" to
sync the data that comes up after that within the line and I suppose it could
be part of a line and the data afterwards, but that clock is supposed to be
a sine-wave not a triangle wave and the succeeding lines  like like they contain
plain old video.

I know !  It's from an old Leave it  to Beaver show  !

If you are going back that far, it could even be the ''overnight signal'' CBC TV broadcast so you knew your TV still worked but there was nothing to watch, except for those insomniacs...

RS-170? Sure, you betcha. Here is an image from the waveform.

OK....  So what are we missing, TJ ?

Not sure  if that is anything I've seen from Leave it To Beaver though ?

I did not have quite enough information to get that full picture.   And, there
was no color burst so am not sure what portion of the picture that was except
maybe the vertical interval which can not have that sometimes  UNLESS, maybe
your capture was severely bandwidth limited in which case only the chrominance
or low frequency luminance would be visible.  But the picture is obviously color.

Okee dokee...no color with this one..

[onanparts]

And then there is this one too. 

[onanparts]

Another hint.... Or two.

[onanparts]

Let's see if this clue nudges anybody in the right direction?

[boB]

Alignment or focus and/or convergence but convergence usually used dots or crosshatch

OK, I will have to settle for an "F" on this one I think.

Final clue....

[mike90045]

still obtuse
Sort of see a smith chart in the "giant asterisk" starburst thing.

[RossW]

Final clue....

The bottom-left looks like a vectorscope display, suggesting several colour bars (roughly equal length lines at roughly the same angle from each other - perhaps 10 colourbars?), plus a few other pure-colour areas.

Diagram top left and middle left make me think it's something to do with a laserdisc.

Perhaps your object is a laser-disc alignment/test disc?

[boB]

Well now !  With that final clue, it looks kinda like a video positioning sensor for a round-house for trains.

Of course, Ross W's idea of a laserdisc is kind of plausible but I'll go with the train concept.

At least a position sensor because of the quadrant enumerators  -I,  I,   II,   etc...
