The '''Tektronix 575''' is a curve tracer for transistors, [[introduced in 1957|introduced in March 1957]].
The '''Tektronix 575''' is a curve tracer for transistors, [[introduced in 1957|introduced in March 1957]].
It can be thought of as being composed of three modules: an X-Y display, a step source, and a collector sweep source.
It can be thought of as being composed of three modules: an X-Y display, a step source, and a collector sweep source.
Unlike later curve tracers, the 575 can optionally display base voltage on the vertical axis.
