What happened to analog scopes? Are all new scopes digital?
As late as 1985, many of the scopes in industrial use were analog, lightweight, rugged, 100 MHz, dual channel models. The best ones had metal multi-turn knobs for a delayed sweep function and had slope and level controls for triggering. (Google "Analog Scopes" for many virtual museum sites - some that track back to the very beginning.)
Analog lab (bench) scopes were large and heavy mainframes with modular plug-ins that determined timebase, BW, and signal conditioning. Some went to 1 GHz. Special scope screen adapters offered Polaroid picture recording of screen shots. Lab note books got thicker. Analog scopes owned highly valued "first solution" history with some of the hardest problems in the early game of electronics. They eliminated the guessing of what circuits were doing as engineers could actually see electronic reality in real time. Analog scope users were intensely loyal to their veteran accomplished favorite tool. Analog scope knobs and switches clicked with fine gun like craftsmanship. They felt rich. Some were adorned with calibration stickers that looked like victory flags. They sat on large carts for mobility. When they were turned on, things were serious in the lab.
Early digital to analog competitive scope comparisons often favored analog. The analog scope could re-trigger so much more quickly that it could often reveal events that first and second generation digital scopes missed. Early DSO adopters usually kept their analog scopes nearby so they could cross check and see what was really happening with the scope they trusted the most.
Steady progress in DSO technology now have bench and portables units with nearly 99% new market share. Analog scopes have served with distinction. Their performance, low cost, and durability were very challenging to digitally simulate and exceed. The modern DSO has grown to far beyond the analog model and today hosts many new, improved, and well accepted functions. A great first analog product series forced a better serving digital scope evolution.
Once a signal is digitized, digital scope capabilities and functions transcend what most could have imagined "just a scope" could ever accomplish.
