Engineers Study The Strangest Things

The engineer is a Brit obviously. What we Americans call a ‘scope probe – meaning oscilloscope probe – he calls a CRO probe – meaning cathode ray oscilloscope probe. Well obviously there are no cathode ray tubes (sort of like a television display tube) in modern ‘scopes. But the term has stuck. For the Brits anyway. BTW the ‘scope I was able to buy due to the generous donations of our readers is a CRO scope. I still like the old technology. You can do things with it that are difficult or impossible to do with a modern digital scope. OTOH capturing images the way the engineer in the video does is quite difficult with the old instruments. You could do it with a scope camera. But those are hard to come by these days. When I was working at Raytheon Computer back in the 60s we used a Polaroid scope camera to document our results. I probably took a hundred pictures a day for weeks on end. We were testing early computer chips (TTL in case you want to know) for use in the inter route displays for air traffic control. Some fun.
