Congure Your Keysight B2900A Series Precision Source/Measure Unit

The Keysight B2900A Series Source/Measure Unit (SMU) series contains the following four models.

–B2901A Precision Source/Measure Unit, 1ch, 100fA resolution, 210V, 3A DC/10.5A pulse

–B2902A Precision Source/Measure Unit, 2ch, 100fA resolution, 210V, 3A DC/10.5A pulse

–B2911A Precision Source/Measure Unit, 1ch, 10fA resolution, 210V, 3A DC/10.5A pulse

–B2912A Precision Source/Measure Unit, 2ch, 10fA resolution, 210V, 3A DC/10.5A pulse

This conguration guide has step-by-step instructions to help you congure an SMU and its related accessories to meet specic test

requirements. For detailed specications, refer to the B2900A SMU series data sheet (publication number 5990-7009EN).

Step 1. Select B2900A Series model

There are two key parameters you need to select up-front: the number of measurement channels (one or two) and the SMU perfor-

mance level. The B2900A series comes in both standard (B2901A/B2902A) and high-performance (B2911A/B2912A) versions. Note:

After purchase it is not possible to upgrade an SMU to have more channels or to the high-performance version (if you currently have

the standard version).

The following items are supplied standard with each B2900A series SMU:

Step 3. Select optional accessories (continued)

Step 3-2. Determine if you need to make 4-wire or guarded measurements

The B2900A SMUs support both 2-wire and 4-wire measurement. The default connection scheme is the simpler 2-wire conguration,

which uses only the force terminals. In 2-wire mode the sense terminals are left open.

If you are measuring very small resistances or applying very large currents then you should use the 4-wire measurement method (also

known as the Kelvin method). This technique uses both the force and sense terminals, and by making the measurement through the

sense terminals (in which no current is owing) the effects of cable resistance are eliminated.

Low current measurements (< 1nA) require guarding to prevent leakage through the measurement cable. The schematic shown below

provides a simplied overview of the guarding technique. Guarded measurements require the use of triaxial cables. A follower (x1)

buffer amplier keeps the guard conductor at the same potential as the center conductor. Since there is no voltage difference, no

current can ow from the center conductor to the guard. Note: In this example, even the test xture has a guarded shield to prevent

leakage at the test xture.

Step 3. Select optional accessories (continued)

Step 3-3. Consider interlock circuit (optional)

To prevent accidental exposure to dangerously high voltages, the B2900A SMUs have a safety interlock. They cannot source voltages

greater than ± 42 V unless the interlock circuit is closed. This is achieved using pins 16 and 24 on the rear Digital I/O output. Normally,

these pins are routed to a shielding box or test xture that must be closed to complete the interlock circuit.

If you are using the 16442B test xture then you can use the N1294A-011 or 012 interlock cables to connect to the interlock circuit. If

you are not using the 16442B then you should install an interlock circuit as shown in the gure below. For more detailed information,

please refer to “Installing the Interlock Circuit” in the Keysight B2900A Series User’s Guide.

Step 3-4. Determine if you use the B2900A series with multiple free software control options (optional)

The B2900A series has multiple free software control options, allowing you to choose the solution that best ts your particular application.
