The Tektronix 370A Programmable Curve Tracer is a DC parametric characterization instrument engineered for detailed device analysis across transistors, thyristors, diodes, SCRs, MOSFETs, optoelectronic components, solar cells, and solid-state displays. It combines precise voltage and current sourcing with high-resolution measurement and automated test sequencing, making it suited for R&D labs, manufacturing test floors, incoming inspection, process monitoring, component matching, and failure analysis.
