Keysight Technologies LED IV Measurements Using the Keysight B2900A Series of SMUs Keysight B2901/02/11/12A Precision Source/Measure Unit Keysight B2901A Precision SMU, 1ch, 100 fA resolution, 210 V, 3A DC/10.5 A pulse Keysight B2902A Precision SMU, 2ch, 100 fA resolution, 210 V, 3A DC/10.5 A pulse Keysight B2911A Precision SMU, 1ch, 10 fA resolution, 210 V, 3A DC/10.5 A pulse Keysight B2912A Precision SMU, 2ch, 10 fA resolution, 210 V, 3A DC/10.5 A pulse Technical Overview Introduction The energy efficiencies and durability of light emitting diodes (LEDs) have led to their increased usage in a variety of applications such as lighting,display panels, etc. This has also spawned research into new types of LEDs with even higher energy efficiencies and properties tailored for specific applications. The Keysight Technologies, Inc. B2901/02/11/12A Precision Source/Measure Unit is a compact and cost-effective bench- top Source/Measure Unit(SMU) with the capability to output and measure both voltage and current. The B2900A Series of SMUs enables you to make a wide range of current versus voltage (IV) measurements more accurately and quickly than B2901/02/11/12A ever before. In addition, the B2900A Series of SMUs comes with High force A an intuitive graphical user interface (GUI) and free PC-based - application software that make it easy for you to begin making V productive measurements immediately. These features make the - B2900A Series of SMUs the best solution for accurate electrical characterization of LEDs. Low force Figure 1. Using the B2900A Series of SMUs to characterize Figure 1 illustrates the connections necessary to measure the an LED basic IV parameters of an LED using a member of the B2900A Series of SMUs. While this technical overview will focus on IV characterization of LEDs using a single-channel model of the B2900A Series of SMUs, if you need to perform optical tests in addition to electrical tests then a dual-channel models of the B2900A Series of SMUs can be used. The dual-channel models of the B2900A Series of SMUs permit one channel to measure photo diode current and the other channel to drive the LED. This is described in the technical overview, LIV Test of Laser Diode Using the Keysight B2900A Series of SMUs (5990-7115EN). What is the B2900A Series of SMUs? An SMU combines the capabilities of a current source, a voltage source,
