Tektronix 370B

Programmable Curve Tracer
The Tektronix 370B is a used  Programmable Curve Tracer.

The Tektronix 370B provides up to 20 A/2,000 V sourcing capability combined with 1 pA and 50 micro V measurement resolution. The 370B performs DC parametric characterization of integrated circuits, transistors, thyristors, diodes, SCRs, MOSFETs, electro-optic components, solar cells, solid-state relays and other semiconductor devices. It has push button source and measurement configuration so it's easy to change from one test to the next.
