Conclusion

The Keysight B2980A Series of Femto/Picoammeters and Electrometers/High Resistance 
Meters offers not only the best-in-class measurement performance, but also unprecedented 
measurement features that can maximize your measurement confidence. The 0.01 fA (10

-17

 

A) minimum current resolution is available for both Femto/Picoammeters and Electrometers/
High Resistance Meters and should meet most of your existing and future sensitive current 
measurement needs.

In addition to its excellent measurement capabilities, the B2980A series can use an external 
trigger to make current measurements. This ability to synchronize accurately with other 
instruments expands your test flexibility. You can further improve your measurement fidelity by 
using a B2980A series battery-powered model to eliminate AC power line noise.
