B2980B Series Femto/Picoammeter and Electrometer/High Resistance Meter

Data Sheets

The world’s only graphical Picoammeter/Electrometer that can confidently measure down to 0.01 fA and up to 10 PΩ


Product Overview


Unique capabilities and features maximize confidence for sensitive measurements


Keysight B2980B Series of Femto/Picoammeters and Electrometers/High Resistance Meters not only offer best-in-class measurement performance, but also provide unprecedented features to maximize your measurement confidence. The Femto/Picoammeters and Electrometers both offer 0.01 fA (10-17 A) minimum current resolution, which meets virtually all existing and future low-level current measurement needs. The electrometers feature a 1,000 V voltage sourcing capability that supports up to 10 PΩ (1016 Ω) resistance measurements. The electrometers also work with Keysight’s well-proven high resistance meter accessories. Both the Femto/Picoammeter and Electrometer have battery powered versions to eliminate AC power line noise. This available capability provides an unmatched level of noise reduction, enabling low-level measurements that were previously impossible.


Unlike conventional picoammeters and electrometers, the B2980B series possesses a 4.3” color LCDbased graphical user interface (GUI) that provides multiple options for viewing data. In addition to numeric format, data can also be viewed as a graph, as a histogram and as a trend chart. These unique frontpanel capabilities facilitate the capture of transient behavior and provide the ability to make quick statistical analyses without the need for a PC. The B2980B series also has features to help you maintain measurement integrity on the external cabling and fixturing. The available Setup Integrity Checker software permits the comparison of noise levels for different cabling and fixturing arrangements, allowing you to identify and isolate the noise-sensitive areas in your measurement system. In addition to these impressive measurement capabilities, the B2980B series has easy-to-use and convenient measurement assist functions that permit users with limited or no electrical engineering training to perform complicated electrical characterization operations with ease.


To provide flexibility and enable you to purchase an instrument with the exact amount of testing capability for your needs, the Keysight B2980B series offers four product versions.

Why is 0.01 fA resolution important?


Many materials science and device characterization applications require the ability to measure very small currents that conventional DMMs (digital multi-meters) cannot handle. Since the B2980B series provides a best-in-class 0.01 fA current measurement resolution in both its Femto/Picoammeter and Electro-meter versions, it can perform precise and detailed measurements that were previously impossible using conventional picoammeters and electrometers. Therefore, you are assured that your current measurement requirements will be met well into the future.
