Data Sheets

Innovative SMU Provides Superior Performance and Rapid Measurement Results

The Keysight B2900A Series of Precision Source/Measure Units are compact and cost-effective bench-top Source/Measure Units (SMUs) with the capability to source and measure both voltage and current. These capabilities make the B2900A Series ideal for a wide variety of IV (current versus voltage) measurement tasks that require both high resolution and accuracy.

The B2900A Series provide best-in-class performance for a modest price. They have broad voltage (±210 V) and current (± 3 A DC and ±10.5 A pulsed) sourcing capability, excellent precision (minimum 10 fA/100 nV sourcing and measuring resolution) and possess a superior color LCD graphical user interface (GUI).

In addition, several task-based viewing modes dramatically improve productivity for test, debug and characterization.

The B2900A Series offers unmatched measurement throughput and supports conventional SMU SCPI commands for easy test code migration. These features improve efficiency and lower the cost of ownership when integrating the SMUs into systems for production test.

The B2900A Series consists of four models, the B2901A, B2902A, B2911A and B2912A, differentiated through their available features (number of digits displayed, measurement resolution, minimum timing interval, supported viewing modes, etc.) and by the number of SMU channels (one or two) they contain. This makes it easy to select the exact price/performance point you require to meet your testing needs.

The Best SMU Solution for a Broad Range of IV Measurements

SMUs are popular and widespread instruments for performing IV measurements in many different fields and applications due to their integrated voltage and current sourcing and measurement capabilities. The Keysight B2900A Series provides superior performance and usability at a very reasonable price.

In addition, the Keysight B2900A Series supports many functions to speed up production test and increase throughput. The versatile measurement capabilities of the B2900A Series SMUs make them an ideal choice for a variety of IV measurements such as semiconductor test, active/passive component test and general electronic device and material characterization.

The B2900A Series has a broad application range that spans uses from R&D and education to industrial development, production test and automated manufacturing. Moreover, they work equally well as either standalone or system components.

Integrated Source and Measurement Capabilities Simplify Difficult IV Measurement Tasks

The Keysight B2900A Series reduces measurement complexity

Performing IV measurements with conventional instruments such as voltage/current sources, arbitrary waveform generators (AWGs), switches, and voltage/current meters is complicated and confusing. It requires deep technical knowledge of both the measurement technique and the instrumentation to perform an accurate measurement.

The Keysight B2900A SMU integrates many different source and measurement capabilities into one compact form factor. It can operate as a seamless 4-quadrant precision voltage/current source, an electrical load, an accurate voltage/current meter, a pulse generator and an AWG.

Its versatile all-in-one integrated source and measurement capabilities allow it to perform a wide variety of measurements from DC to low frequency AC without the need to change connections or use additional equipment. Moreover, the availability of 2-channel models supports the testing of devices with up to three terminals (as long as one terminal can be tied to the circuit common).

If you wish to learn more about the advantages of using SMUs to make IV measurements, then please refer to the section at the back of this brochure entitled “Overview: Why use an SMU?”

Wide Voltage and Current Coverage for Testing a Variety of Devices

Test up to 210 V and 3 A (DC) or 10.5 A (pulsed) with a single instrument

The B2900A SMUs can source and measure voltages of ±210 V and currents of ±3 A (DC) or ±10.5 A (pulsed). This versatility allows you to standardize on a single SMU model and minimize support costs. These capabilities are present on both single and dual channel versions, since on the 2-channel versions both channels can be operated completely independently.

Integrated sweep and arbitrary waveform measurement functionality

The B2900A Series has capabilities that allow it to perform more than just simple DC and pulsed measurements. The B2900A SMUs have a built-in sweep capability that supports all of the standard sweep parameters such as linear and logarithmic modes, single and double sweep functions and constant and pulsed sweep operation.

The B2900A GUI fully supports the sweep measurement function, thereby allowing sweep measurements to be made and displayed quickly from the instrument front panel.

Of course, the user can also make the same sweep measurements just as efficiently on the B2900A SMUs under remote control using SCPI commands. This integrated sweep measurement capability improves efficiency and reduces measurement setup time.
