With graphical touchscreen and open source scripting language, Keithley 2461 High Current SourceMeter SMU Instrument is used for creating 10 A/100 V, 1,000 W high-current pulses that minimize power device thermal effects and maintain device integrity. Dual 18-bit, 1 MSps digitizers enable SMU to measure and visualize actual device operation, waveforms, and transient events of current and voltage simultaneously. DC and pulse source and sink performance foster in-depth insight.
