Keithley Instruments, Cleveland, OH, has introduced the Model 2450 SourceMeter® SMU instrument, the first benchtop source measure unit (SMU) instrument with a capacitive touchscreen graphical user interface. The instrument is based on the company’s Touch, Test, Invent™ design philosophy that lets users interact with the instruments via the touchscreen and icon-based control. The instrument combines the functionality of a power supply, a true current source, 6-1/2-digit multimeter, electronic load, and trigger controller. It features a 5" touchscreen, low current and voltage ranges to eliminate the need for separate instruments, built-in help via the touchscreen, and KickStart start-up software. Data can be stored to disk and exported to another software environment. The unit integrates the capabilities of I-V systems, curve tracers, and semiconductor analyzers in one instrument.
