Interesting marketing video from Tektronix in 1983.
Their scopes vs the competition.
It is 1 hour but fun to watch.
It's a shame they didn't apply the same comparison to their horrific first generation DSOs.
We did! ------& sent the Tek (& HP) sales critters home "with their tails between their legs"!

In fairness to the competitors they did compare with, some of the things they compared here are not anything an experienced user would have problems with.
For instance, looking at high frequency sine waves.
If you could see umpteen cycles on the screen but not resolve some on, say, the Philips 'scope, you would simply use the delayed timebase to display one or several cycles-----which is exactly what you would do with the 2215.
One thing which they obviously couldn't directly compare was longevity ----- a Philips 3217 still in working order is a fairly rare commodity, but there are many working Tek 2215s around.
