Semiconductor Curve Tracer


Model 501A

  • Display characteristics curves for
    all semiconductor devices on
    your scope
  • Measure breakdown voltage
    non-distructively
  • Identify unknown devices
  • Complete with FP-5 probe

Each different type semiconductor device has its own set of unique characteristic curves. by examining these curves you can determine operating characteristics of the device you are testing-including gain (beta), cutoff current, leakage current,output addmitance and any other measurable specification. The 501Asimulates actual operating conditions by applaying sweep voltage to the collector while varying base current (voltage for FET's) in five steps. After making the simple connection to any scope with an external horizontal input you can observe the characteristic curve.
