The Keithley Model 2450 is a next-generation SourceMeter SMU (Source Measure Unit) instrument that enables true testing according to Ohm's Law (current, voltage, and resistance). The innovative graphical user interface and advanced capacitive touchscreen technology allow for intuitive operation with a minimal learning curve, enabling engineers and scientists to invent more easily, work smarter, and learn faster. The Model 2450 is a versatile SMU suitable for all applications: it is particularly well-suited for characterizing today's modern semiconductors, nanometer components and materials, organic semiconductors, printed electronics, and other microelectronics and low-power components. All of this is combined with Keithley's legendary precision, resolution, accuracy, and reliability. Engineers and scientists benefit from a new and intuitive ease of use in source-measure testing, following the motto Touch, Test, Invent.
