The energy efficiencies and durability of light-emitting diodes (LEDs) have increased usage in various applications such as lighting, display panels, and a wide range of consumer electronics products. This technology has also spawned research into new types of LEDs with even higher energy efficiencies and properties tailored for specific applications. Your source / measure unit (SMU) of choice needs to have an intuitive graphical user interface (GUI) and multiple software control options that make it easy for you to begin making measurements immediately. These software flexibilities enable you to measure the IV curve of your LEDs for any application.
