   The Tektronix 577 Curve Tracer system offers a convenient method of presenting dynamic characteristic transistor curves and a wide range of other semiconductor devices. The 577  allows dc parameter characterization of transistors, thyristors, linear ICs, diodes, SCRs, MOSFETs, optoelectronic components, solar cells, solid state displays and other semiconductor devices. Expanded parameter measurements are available for linear op-amps, SCRs and three terminal regulators when using one of three application specific adapters with the 178 Test Fixture (not-included)

   The Tektronix 577 Curve Tracer provides for low current measurements with storage display capabilities and also allows characteristic curves of two devices to be overlaid. The Collector supply (five modes, five ranges) provides 6.5 V/10 A, 25 V/2.5 A, 100 V/0.6 A, 400 V/0.15 A, 1600 V/0.04 A. Current increments: 5nA/step to 0.2 A/step +/-2%. Voltage increments: 5 mV/step to 2 V/step +/-2%.
