Why is 0.01 fA resolution
important?
Many materials science and device
characterization applications require
the ability to measure very small
currents that conventional DMMs
(digital multi-meters) cannot handle.
Since the B2980A series provides
a best-in-class 0.01 fA current
measurement resolution in both
its Femto/Picoammeter and
Electro-meter versions, it can
perform precise and detailed
measurements that were previously
impossible using conventional
picoamme ters and electrometers.
Therefore, you are assured that your
current measurement requirements
will be met well into the future.
