The Agilent/Keysight Technologies B2987A 6 1/2-digit Electrometer / High Resistance Meter with Li-ion Battery, 0.01 fA to 20 mA, 2 pA, Refurbished not only offers best-in-class measurement performance, but also provides unprecedented features to maximize your measurement confidence. The B2987A offers 0.01 fA (10-17 A) minimum current resolution, which meets virtually all existing and future low-level current measurement needs. The B2987A electrometer features a 1,000 V voltage sourcing capability that supports up to 10 PΩ (1016 Ω) resistance measurements. This battery-powered versions eliminates AC power line noise, providing an unmatched level of noise reduction and enabling low-level measurements that were previously impossible.

The Keysight B2987A possesses a 4.3 inch 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 B2987A also has features to help you maintain measurement integrity on the external cabling and fixturing. In addition to these impressive measurement capabilities, the B2987A 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.
