Printed in Malaysia Part Number B2910-90100 What is the B2900 SMU? 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. This gives it the ability to evaluate the IV characteristics of devices across all four measurement quadrants without the need for any additional equipment. In addition to its DC operation mode, B2901B/B2902B/ B2911B/B2912B also have the ability to perform pulsed measurements in order to prevent device self-heating from distorting the measurement results. - A - V Voltage source Current meter Current source Voltage meter 2-Wire and 4-Wire Connections To simplify the connections, use 2-wire connection by connecting the Force terminals only and opening the Sense terminals. For low resistance measurements and high current measurements, use 4-wire connection. Connecting the Force and Sense lines together at the terminal of the DUT minimizes the measurement error caused by the residual resistance of the test leads or cables. Grounded and Floating Measurements With the default setting, Low Force terminal is connected to the chassis ground. However, it can be disconnected from the ground for floating measurements. This setup is effective for differential voltage measurements which usually require two channels as shown in the Grounded 2 connection. DUT Grounded 1 DUT Grounded 2 High Force Low Force DUT Floating SMU High Force Low Force SMU High Force Low Force SMU High Force Low Force SMU For the floating measurements, set the Low Terminal State to FLOATING on the Output Connection dialog box. With the default setting, it is set to GROUNDED. The dialog box is opened by pressing the Config > Source > Connection function keys. With the FLOATING setting, the Low Force and Low Sense terminals can be connected to the maximum of ±250 V. WARNING: Potentially hazardous voltages of up to ±250 V may be present at the Low Force and Low Sense terminals. To prevent electrical shock, use accessories that comply with IEC 61010-031. The terminals and the extended conductors must be isolated by using insulation caps, sleeves, etc. DUT 4-Wire DUT High Force Low Force SMU 2-Wire High Force Low Force SMU High Sense Low Sense
