Both the picoammeters and electrometers provide a world-best performance of 0.01 fA (0.01 x 10-15 A) current measurement resolution. In addition, the electrometers can measure resistance up to 10 PΩ (10 x 1015 Ω), which is also a best-in-class specification. Finally, since AC power line noise can be difficult to eliminate when making low-level measurements, both the picoammeters and electrometers are available in battery powered versions.
All B2980A series products have a 4.3” liquid crystal display that supports a variety of viewing modes (numeric, trend chart and histogram), which eliminates the need to perform data analysis on a PC. Also built-in Real-time Noise Monitor helps you to select the appropriate measurement. These unique capabilities enable you to capture transient device and material behavior and to make quick statistical analyses on the spot, thereby greatly increasing measurement confidence and efficiency.
Optional Setup Integrity Checker software is available to help you isolate the cause of noise arising from external setup elements, such as cables, connectors, adapters, chambers, etc.
