The Type 575 Transistor-Curve Tracer displays the dynamic characteristic curves of both NPN and PNP transistors on the screen of a 5-inch cathode-ray tube. Several different transistor characteristic curves may be displayed, including the collector family in the common-base and common emitter config
A vintage Tektronix Type 575 Transistor-Curve Tracer, an electronic test instrument used to display the dynamic characteristic curves of NPN and PNP transistors. This piece of nerdy vintage hardware features a 5-inch cathode-ray screen and a complex array of knobs and switches.
