The above is on ebay but I wonder if an add on interface is available for a standard oscilloscope. I sort of remember something some years ago in a magazine and may be "Television" as a project.
The other would be p.c based via interface and software although never seen them in action.
Fortunately they are not really required these days as stated.

Like I mentioned before, there is no problem in using a scope to look at the video. You can still see/measure the majority of components of a video signal...difference being that waveform monitor is specifically designed for viewing composite video in a more detailed form. Sorta like viewing it under a magnifying glass. It is also a great tool in troubleshooting various video color/luma issues & keeping live broadcast video to near "perfect" levels.

As a matter of fact unless you work in a live broadcast/studio enviroment or R&D where precision monitoring of video is required, using a waveform monitor is rather expensive & an overkill.

Ok, well I guess I'll try to get a few bucks for it somewhere. But is there no way to make this work to monitor my video levels?
I can't believe it. I was so excited, thinking I'd found a waveform/vectorscope. And so cheeep!

k,

Can't really compare to computers. But it is definitley outdated in todays technology. A 25 mhz scope is pretty much limited with most if not all todays technology where 60~200mhz scopes are the norm. It simply not able to handle a lot of complex signals & has limited use in today's field

However it is perfectly useful for lets say, a hobbyist or someone that works on the side, student etc.

I guess I could try - but is it a piece of obsolete equipment that no one would use? like a pentium 2 computer? Or is it something that, even though it's older, would still be a good buy for someone and applicable to today's technology? And if so who would me most likely to use this?
I did do a Google search but didn't find much. However I'l do a more extensive search and check it out.

'fcourse you can try selling it & someone will pay for it. As to how much?
Just don''t know. suggest doing a search & get some ideas

And if I did sell it, what would it be worth?
(For some reason this isn't giving me the option to edit my earlier post)

[Kell555]

Yes, that was what I thought it was.
Is there any market for this thing or is it totally obsolete? Maybe I could sell it on ebay?

Sounds like a mistake in buying......

While an oscilloscope can be used to monitor video & similar to a waveform monitor/vectroscope, it is not the same thing.
Waveform monitor is mainly used to analyze sections of a waveform in much more detailed form & used extensively in broadcast facilities to monitor all aspects of a video signal(ie; color/luma/sync.etc)

While there is nothing wrong with a PM3214, it's a basic Analog 25MHZ scope (rather obsolete & not sure where to get a manual---proly someone sells on the net)

Here is an example of what you proly had in mind:

Hi -
I bought this at a yard sale today. Does anyone know where I can get a manual for this thing?
Also, I may have, well, egg on my face for asking this. But oh well.
When I was in school for TV production, we used a waveform/vectorscope. It looked like this and that's why I bought it, but I'm not sure I've bought the right thing. I took the video out from a monitor just to see if this is a working piece of equipment. I played around with it for awhile, but I don't see any of the screens I recall which monitored the levels coming out, or the colors. It's possible I'm just doing this wrong, unless of course i've bought the wrong thing. Hence my need for a manual, and advice from someone in the know.
Help---?
Thanks
