While I was working on the [[541|540 series]] vertical amplifier, [[Virgil Briton]], whose bench was next to me, had put together a vacuum tube curve tracer using stepping relays and other mechanical devices. I remember thinking that, that was a neat display even if it did a lot clicking and was slow. After putting the cross hatch generator together, I knew it would be very easy to do the curve tracer electronically,it started for in house use,but after putting a self-contained instrument together, Tek decided to call it 570 and sell it.

==Notes==

''Note 1:'' The original quote refers to the 575, however, the first curve tracer was the [[570]] in 1955; the [[541]] was released in 1955 as well, and the text continues to tell the [[575]] story.

It follows that the instrument referenced is clearly the 570, not the 575.
