The 571 is a curve tracer. It can show the characteristic curves of PNP and NPN bipolar transistors, both N- and P-channel FETs, diodes (including Zener types), and SCRs. It is a microprocessor-controlled device, and user interaction is done through navigation keys. A typical sweep run takes about five seconds. It has a parallel printer output that can print graphics on Epson-protocol dot-matrix printers. | The 571 is a curve tracer.

This makes comparison and matching between devices easy. | ||
The 571 has a well-designed field of parallel-connected sockets to accommodate many different semiconductor package types. Details can be seen in the photographs below. | The 571 has a well-designed field of parallel-connected sockets to accommodate many different semiconductor package types.
