Hey Everyone,

I've got an interesting situation. I'm the IT guy at my company, and we just acquired a scanning electron microscope. I've been asked to put a video capture computer in so that we can save the images it displays. The problem is that the video output is RCA cables, Red, Green, and Blue. What I'm trying to do is either find a Capture Card or box which accepts RGB inputs, or a converter which will allow me to change the RGB inputs into something that can be captured.
Any ideas?

But I would be interested to know what happens here.

The only RCA things that I've seen used with the more common Computer Hardware where some High Resolution Monitors and that was a long time ago now, They had a VGA out to RGB with Horizontal and Vertical Sync leads all RCA type sockets. I haven't seen any of these in a very long time either and they where a very limited unit so there where not many of them around.

As for converting RGB to Composite Video I think you'll be stuck with using some form of Professional Video Recorder to feed the Signal to and then with a composite output feed the computer through a Video Capture Card. This might not be ideal but I think it's the only answer here and you'll need to check the shielding of everything used here as SEM while fairly well shielded you still need to protect any hardware close to them from any stray radiation of any kind.

I hope that helps you some.

I think you're right. I'm going to have to get an expensive professional video device. I've found a company that makes some, Matrox. They practically custom make the devices for you. I'm sure it will be a couple thousand dollars though... I suppose that isn't too much compared to the price of the SEM. We'll see if I can get that approved though!
