Source meter By Keithley 2450

The Keithley 2450 SourceMeter is a versatile, fourth-generation source measure unit (SMU) that brings Ohm's law testing to the fingertips with its innovative 5-inch capacitive touchscreen. This single-channel, all-in-one instrument combines a precision power supply, current source, digital multimeter (DMM), electronic load, and trigger controller. It is particularly well-suited for characterizing modern scaled semiconductors, nano-scale materials, organic electronics, and lighting technologies like LEDs and solar cells. The 2450 provides highly flexible, four-quadrant operation, meaning it can both source and sink (act as a load) voltage or current, with a maximum output of 200 V, 1 A, and 20 W. The device is known for its high precision and accuracy, offering 6½-digit resolution and a basic measure accuracy of 0.012%
