I picked up this waveform monitor after work today. It was offered up for free on Craig’s List and was right on my way home. I used a very similar model extensively during my early career. This device displays a waveform which represents a video signal and is a key diagnostic tool for evaluating signal quality and compliance with standards (the square wave pictured here was all I had handy to run through it). I cleaned it up and put it through its paces. Everything functioned perfectly. The two hours I spent testing took me on something of a technical stroll down Memory Lane right back to the days of Truevision, the company I co-founded. Unlike my more general purpose oscilloscope, however, I have no practical application for this piece of equipment, especially since the world has gone high definition which uses a different signal standard. I put it up on eBay with a starting price of one cent in hopes it will find a good home.
