Typically, a pattern generator is the thing.

If you own a Nintendo Wii, you can do an easy (and reversible) soft mod on it to allow homebrew apps, and get a copy of 240p test suite on it.

The Wii is really good for this as it outputs composite, s video and component.

240p test suite also exists for many other systems, but they obviously require you buy a cartridge version which is more expensive.

Another way to do it is to get a VGA to composite adapter and hook up a PC to it with a VGA output.

Yet another option is to find a test pattern DVD image online, burn it to a DVD player, and play the DVD.

You can of course just go buy a pattern generator, but a good working one is starting to get expensive. When I was buying them, they were cheap.

Don't buy a Heathkit one, they are flakey. I've gone through 2 of them and the ICs both died.
