The 577D curve tracer allows dc parameter characterization of transistors, thyristors, linear ICs, diodes, SCRs, MOSFETs, optoelectronic components, solar cells, solid state displays and other semiconductor devices. By selecting one of three application specific adapters with the 178 plug-in, expanded parameter measurements are available for linear op-amps, SCRs and three terminall regulators.

Typical measurements include leakage, breakdown voltages up to 1600 volts, MOSFET (Vgs(th), SCR Vgt/lgt, Diode Vf, ZENER Vz/Vf, resistance as well as other dc parameters.
