Robert:

Any of the old remotes would probably work to experiment with for a transmitter. They would all have the related protocol for whatever device they were controlling, but that wouldn't matter, if you just want to prove out the method you use to capture the output on the Saleae. Yes, the LED is part of the transmitter.

You need a IR receiver as well. Some folks just use a photo transistor, I would recommend a good IR receiver, since they have additional features built in. I am using a TSSOP 32338, but there are a multitude of receivers available.

Here are a couple of good links on this subject:

If you want, I can post a couple of screen shots of my results, first a sample of an actual transmission from a TV remote, and then one of the duplicates using a PIC to output the pattern.
