# Keysight B2912B 210 V Precision Source/Measure Unit (2-Channel) (Pre-Owned) # Keysight B2912B 210 V Precision Source/Measure Unit (2-Channel) (Pre-Owned) ## Key Features At A Glance - Family spans precision source/measure units, low-noise power sources, and femto/picoammeter electrometers - 6.5-digit source and measurement resolution available across the source/measure and low-noise source models - Source and measure from 100 nV / 10 fA up to 210 V and 3 A DC (10.5 A pulsed) across the series - Front-panel display of I-V curves, time domain, and histogram views - Electrometer models measure down to 0.01 fA and resistance up to 10 PΩ with an integrated 1000 V source - ARB capability on low-noise source models with 6 built-in waveforms at speeds up to 10 kHz - Battery-operated models available to eliminate AC power line noise - Multiple software control options: PathWave BenchVue, Graphical Web Interface, and Quick I/V Measurement Software The Keysight B2900 Precision Instrument Family is a set of precision source and measurement instruments built to achieve critical precision source and measurement goals. It brings together three complementary series under one family: the B2900B/BL Series Precision Source/Measure Units, the B2960B Series Low Noise Power Sources, and the B2980B Series Femto/Picoammeters and Electrometers. Together they cover sourcing, measuring, and characterizing voltage, current, resistance, and charge across an exceptionally wide dynamic range. A source/measure unit combines a precision programmable source with high-resolution measurement in a single instrument, letting an engineer stimulate a device and measure its response together. Within this family, the B2900B/BL units display I-V curves and other graphs directly on the front panel; the B2980B electrometers measure materials and devices down to 0.01 fA and up to 10 PΩ; and graphical time domain and histogram views support quick debug and analysis. These capabilities suit precision characterization of components, materials, and low-level current and charge behavior. ValueTronics has supplied new and pre-owned test and measurement instruments since 1992 from our own 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where we stock and hold our inventory directly. Pre-owned units are inspected and functionally verified in-house by our technicians before shipment, while new units ship factory-sealed exactly as received from the manufacturer. ## Brand Heritage Keysight Technologies traces its measurement heritage to Hewlett-Packard, whose test and measurement business was spun off as Agilent Technologies in 1999 and then established as Keysight Technologies in 2014. ## Compare Other Models in This Series The B2900 Precision Instrument Family is organized into three series that share a common precision philosophy but address different measurement tasks. The B2900B/BL Series are Precision Source/Measure Units that source and measure in a single instrument; the B2960B Series are Low Noise Power Sources focused on ultra-low-noise precision sourcing; and the B2980B Series are Femto/Picoammeters and Electrometers built for the lowest-level current, charge, and high-resistance measurements. Each model in the family is defined by its own type, channel count, source and measurement resolution, and maximum output, as shown in the comparison table below. Selecting the right model is a matter of matching the specific source/measure, low-noise sourcing, or electrometer task to the model whose listed specifications cover it. Each model linked below is its own dedicated product page with condition-matched pricing. Choose the pre-owned listing for the specific model that fits your application; specifications shown reflect that model as described in this family's data. The models differ primarily by type and capability. Source resolution ranges from 5.5-digit to 6.5-digit across the source models, channel counts are listed as one or two depending on the model, and maximum output voltage spans 21 V to 210 V on the source/measure and low-noise source models, while the electrometer offers an integrated 1000 V source. Maximum DC output current likewise varies across the family, up to 3.03 A on the higher-current source models (10.5 A pulsed). Functional differences also separate the series: ARB waveform generation is provided on the low-noise source models, battery operation is available on select femto/picoammeter and electrometer models to eliminate AC line noise, and resistance and charge measurement appear on the electrometer. Refer to the comparison table that follows for each model's exact resolution, range, output, and supported functions before selecting.
