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.

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.

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.
