That beast we call the oscilloscope has come a long way over the years. The first one I ever used was a huge Tektronix behemoth that had vacuum tubes and rolled around on a "ScopeMobile". The bandwidth was barely above audio and it only had 2 channels. Now I use a handheld digitizing scope with 4 channels, 200 MHz bandwidth, and all sorts of bells and whistles.
Watching the evolution of test equipment is one of the best things about being a technician.
