Developing and using MOSFETS, IGBTs, diodes and other high power devices requires comprehensive device-level characterization such as breakdown voltage, on-state current and capacitance measurements. Keithley's line of high power Parametric Curve Tracer configurations supports the full spectrum of device types and test parameters. Keithley's Parametric Curve Tracer configurations include everything necessary for the characterization engineer to develop a complete test system quickly. ACS Basic Edition software provides complete device characterization, including both real-time trace mode for quickly checking fundamental device parameters like breakdown voltage and full parametric mode for extracting precise device parameters. ACS Basic Edition goes beyond traditional curve tracer interfaces by offering a broad array of sample libraries. More important, users have complete control of all test resources, allowing the creation of more advanced tests than previously possible on a curve tracer.
