Keithley reveals mix & match power device characterisation software
The firm's flexible parametric curve tracer solutions analyse silicon carbide and gallium nitride power devices
Keithley Instruments has introduced seven instrumentation, software, and test fixture configurations for parametric curve tracing applications.
The software is suited to the characterisation of high power devices of up to 3,000V and 100A.
They’re optimised to provide a cost-effective solution for characterising the growing number of high power semiconductor devices, including those based on SiC and GaN technology.
These systems offer the power required for the vast majority of high power device design and development applications. They address the characterisation and test needs of research, reliability, failure analysis for applications engineers, device designers, inspection technicians and many others.
Lee Stauffer, a Keithley staff technologist, notes, “Many power device developers have told us they like the dynamic range and ease of use of a traditional curve tracer, but they know they need more flexibility in configuring the measurement channels, as well as the accuracy, capability, and graphical user interface that a modern parametric analyser offers.”
All seven Keithley configurations offer the flexibility to add new measurement channels economically as users’ needs evolve, with no need to return the system to the factory to install new hardware.
For example, someone could start with an entry level Parametric Curve Tracer, then add the capabilities of additional System SourceMeter instruments, such as higher voltage and/or higher current, at a later date.
Six different System SourceMeter instrument models can be mixed and matched to create the optimum combination of voltage, current and power for the user’s specific needs.
Keithley’s TSP Link virtual backplane technology makes it easy to incorporate any number of Source-Measure channels. These are fully and automatically synchronised with other SourceMeter instruments in the system.
All seven configurations include the latest version of Keithley’s ACS (Automated Characterisation Suite) Basic Edition software. This supports Keithley’s newest SMUs and takes maximum advantage of the Series 2600B’s TSP-Link connection trigger model, which allows for 500ns trigger synchronisation between instruments.
This tighter synchronisation capability maximizes the high speed pulse mode capabilities of the new Model 2651A and Model 2657A High Power System SourceMeter instruments.
The Windows-compatible ACS Basic Edition package provides control and analysis tools well-suited for high power device characterisation, including complete parametric test libraries for MOSFETs, BJTs, triacs, diodes, IGBTs, and other device types.
The software’s “trace” mode uses an on-screen slider control that works much like the power control knob on a traditional analogue curve tracer, allows users to control the level of voltage and current levels sourced interactively and to see how the power device responds in real time.
The software’s “parametric” mode provides a “fill-in-the-blanks” GUI to configure a test precisely and a comprehensive set of tools for precise parameter extraction. All seven bundles also include all cabling and adapters required for system assembly, as well as a number of sample power devices useful for training and demonstration purposes.
Sales of the parametric curve tracer configurations will begin immediately and units will ship within four weeks ARO.
