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.

One nice feature of the 571 is its ability to store a set of ''reference'' curves, which are displayed as a background for the current curves being traced.  This makes comparison and matching of 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.
