B2900B/B2900BL Series Precision Source/Measure Unit

Data Sheets

Get Rapid and Accurate Measurement Results


The Keysight B2900B/BL Series Precision Source/Measure Units are compact and cost-effective benchtop Source/Measure Units (SMUs) with the capability to source and measure both voltage and current. These capabilities make the B2900B/BL Series SMU ideal for a wide variety of IV (current versus voltage) measurement tasks that require both high resolution and accuracy. 


The B2900B/BL Series SMU has a voltage maximum of ±210 V, a current maximum ±3 A DC, and 


±10.5 A pulsed sourcing capabilities. With a precision minimum of 10 fA/100 nV sourcing and measuring resolution, a color LCD graphical user interface (GUI) and several task-based viewing modes will improve your productivity for test, debug, and characterization.


The B2900B/BL Series SMU offers superior 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 B2900B/BL Series SMU consists of six models — the B2901BL, B2910BL, B2901B, B2902B, B2911B, and B2912B. The differentiation between the models is according to their available features: output range, number of digits displayed, measurement resolution, minimum timing interval, viewing modes, and SMU channels. These model choices make it easy for selecting the performance and price you need for your testing requirements.


Feature                                                      Benefit

Integrated 4-quadrant sourcing and measuring capabilities

Easily and accurately measure current and voltage using a single instrument without the need to manually change any connections

Measurement range: ±210 V, ±3 A (DC),

±10.5 A (pulsed)

A single SMU product covers both high voltage and high current measurement needs, allowing for more standardization and simplifying inventory and support concerns.

Source and measurement resolution down to

10 fA and 100 nV

Can make low-level measurements using a low-cost bench-top SMU that were previously only possible using a more expensive semiconductor device analyzer.

User-friendly front panel GUI with 4.3 inch color LCD display supports both graphical and numerical view modes

Can quickly and easily perform measurements and display data on the front panel, thereby greatly speeding up interactive test, characterization and debug operations.

10 microsecond digitizing capability

Can capture low frequency phenomena in addition to DC characteristics

PC-based control software

Can make measurements remotely from a PC without the need to program.

Supports both conventional and default SCPI commands

Conventional SCPI commands provide some compatibility with older SMU code (such as Keithley 2400 series) to minimize code conversion work. Default SCPI commands support advanced B2900B/BL Series features

Small form factor with USB2.0, LAN, GPIB and digital I/O interfaces

Easy integration into rack and stack systems.
