While I was working on the 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 575 and sell it. | While I was working on the 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.

:''Note:'' The first curve tracer was the [[570]] in 1955; the [[541]] was released in 1955 as well, so the above appears to refer to the 570, not the 575. | |||
