Curve Tracers

Curve tracers as TCT and SCT series.
The curve tracer can measure static characteristics of semiconductors such as transistor, FETs, thyristors, diodes and ICs.
While with the constant measuring instrument or characteristics tester the operator measures a characteristic value at each point by switching the applied voltage, the curve tracer allows the operator to observe a wide range of characteristics at a glance and easily know a characteristic value at each desired point on the curve.

 

TCT-2004

TCT-2004 is a highly-sensitive and multifunctional curve tracer to measure static and dynamic characteristic of semiconductors. it is equipped with digital storage, thereby permitting it to display stationary waveform. Maximum applicable voltage to the collector is }2kV and maximum current sensitivity is 100pA/DIV. Thus, the instrument can precisely measure kinds of semiconductors.
