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 Keysight B2900A Series of SMUs 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 Keysight 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 Keysight 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.

Integrated source and measurement capabilities simplify difficult IV measurement tasks
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).
Test up to 210 V and 3 A (DC) or 10.5A (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 Keysight 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 effi ciently on the B2900A SMUs
under remote control using SCPI commands.
This integrated sweep measurement capability improves efficiency and reduces measurement setup time. In addition to its resident sweep functionality, the Keysight B2900A Series also supports arbitrary waveform generation (AWG) and list sweep capabilities. The AWG and list sweep functions allow you to create waveforms with up to 2500 steps for maximum flexibility, and enable you to specify a waveform of arbitrary shape using familiar spreadsheet compatible data-entry formats. The AWG and list sweep features are especially useful when characterizing devices where the response varies greatly depending upon the applied voltage or current, since they give you the flexibility to “zoom in” on areas of interest.
Source and measurement resolution down to 10 fA and 100 nV
The Keysight B2900A Series consists of four models primarily differentiated by number of channels (one or two) and measurement and sourcing resolution. The B2901A (single channel) and B2902A (dual channel) versions possess 100 fA and 100 nV measurement resolution and 1 pA and 1 μV sourcing resolution.
The B2911A (single channel) and B2912A (dual channel) precision versions possess 10 fA and 100 nV of resolution for both measurement and sourcing. All members of the Keysight B2900A Series support popular banana jack style inputs for cost-effective and flexible connectivity; for low-current measurements below 1 nA, banana jack to triaxial adapters are available.
Capture transient phenomena effortlessly
Keysight B2900A Series supports a high speed sampling measurement function that permits the capture and display of low frequency transient phenomena. The Keysight B2901A and B2902A support a 20 μs (50,000 points/s) sampling rate and the Keysight B2911A and B2912A support a 10 μs (100,000 points/s) sampling rate. Of course, the maximum achievable sampling rate depends on many factors including signal level, ambient noise and desired resolution.
Innovative GUI and 4.3” color LCD display facilitate fast bench-top test, debug and characterisation
Free PC-based software eliminates the need to program
Keysight supplies PC-based Quick I/V Measurement Software with the B2900A Series at no charge.
