Keithley 2430 1kW Pulse SourceMeter (SMU)

The Keithley 2430 1kW Pulse SourceMeter is a single-channel instrument that combines the functionality of a voltage source, current source, voltage meter, current meter, and resistance meter into one unit. It delivers precision sourcing and measurement of voltage and current across a wide range, making it ideal for characterizing power semiconductors, photovoltaic devices, and other high-power components. The tightly integrated source and measurement architecture minimizes test time, simplifies programming, and enhances device protection.
