Product Overview
Unique capabilities and features maximize confidence for sensitive measurements
Keysight B2980A 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 (10
16
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 B2980A series possesses a 4.3” color LCD-based
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 front-panel
capabilities facilitate the capture of transient behavior and provide the ability to make quick statistical
analyses without the need for a PC. The B2980A 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 B2980A 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 B2980A series offers four product versions.
