We also had a nice Zenith Ultrasonic and IR remote tester. It had added features for measuring drive on the System 3 sets, but 90% used for IR remote control testing. I know of only one other way to test ultrasonic remotes sans the TV...the Zenith tester paid for itself over and over. Hard to find, I still have ours. It just uses an ultrasonic mic, and overdrives an op amp to square up things before sending it to both an LED and a scope jack. The iR side sends the IR diode/receiver output along a similar path.

Overkill for a newbie, but it completes my lineup
I know my Zenith 852-240 ultrasonic remote tester can be modded to test IR remotes, but is there another model that's a factory job? Mine has an "output to frequency counter" jack; I'm guessing a scope can be used with mine as well. That would be good because I don't have a frequency counter.
