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. They cover currents from 10 fA to 3 A (DC)/10.5 A (pulse) and voltages from 100 nV to 210 V, which enables you to make a wide range of current versus voltage (IV) measurements more accurately and quickly than ever before. The B2900A Series of SMUs also supports a resistance measurement function that facilitates both low and high resistance measurements. These features make the B2900A Series of SMUs the best solution for accurate characterization of resistors and other devices. Making accurate resistance measurements is actually one of the more challenging areas of measurement science. Many factors can affect the accuracy of a resistance measurement, including residual test lead resistance, thermal electromotive force and leakage currents in the measurement path. The B2900A Series of SMUs possesses a variety of features to address these measurement issues, including a remote sense function (4-wire connection), offset compensation, and a guard function. All of these will be described in greater detail in this technical overview. What is the B2900A Series of SMUs? An SMU combines the capabilities of a current source, a voltage source, a current meter and a voltage meter along with the capability to switch easily between these various functions into a single instrument (please see Figure 1). This gives it the ability to evaluate the IV characteristics of devices across all four measurement quadrants without the need for any additional equipment. Besides being able to output and measure voltage or current very accurately, SMUs also possess a compliance feature that allows a limit to be placed on the voltage or current output to prevent device damage. The members of the B2900A Series of SMUs are single or dual channel SMU units that offer a wide range of IV measurement capability for a variety of two-terminal and three- terminal devices. They cover currents from 10 fA to 3 A (DC)/10.5 A (pulse) and voltages from 100 nV to 210 V. In addition to their DC operation mode, the B2900A Series of SMUs also has the ability to perform pulsed measurements in order to prevent device self-heating from distorting the measurement results. Finally, the B2900A Series
