The B2985A Electrometer/High Resistance Meter is the world’s only graphical electrometer that allows you to confidently measures small currents with 0.01 fA (0.01 x 10-15 A) resolution and large resistances of up to 10 PΩ (10 x 1015 Ω). It possesses a 4.3” color LCD with a graphical user interface that provides trend chart and histogram data in addition to numeric information. These front-panel capabilities enable you to capture transient behavior and to perform quick statistical analyses without a PC. The available Setup Integrity Checker software option allows you to compare the noise levels of different cabling and fixturing arrangements to help isolate external noise sources.
Keysight B2980A Series Femto/Picoammeter and Electrometer/High Resistance Meter
The world’s only graphical Picoammeter/Electrometer that can confidently measure down to 0.01 fA and up to 10 PΩ
Product Series Overview
Unique capabilities and features maximize conidence 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 conidence.
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 B2980A 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 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 ixturing 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.
The B2980A series’ battery operated models eliminate power line noise and enhance low noise measurement performance.
AC power line noise strongly impacts sensitive measurements. While integrating over one or more PLCs can minimize AC power line noise effects, even the B2980A’s excellent noise performance cannot eliminate 100% of this noise unless the instrument is completely isolated. Therefore, both the Femto/Picoammeter and Electrometer have available battery operated versions that enable you to make power-line-noise-free measurements.
The two battery models can function for 7 hours (B2983A) or 5 hours (B2987A) under normal operating conditions, and they also automatically save your measured data and measurement setup information if the battery level goes below 5%. Of course, besides eliminating noise the battery models provide the added beneit of portability allowing you to use them anywhere you want.
