Introduction
The Keysight Technologies, Inc. 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 as you expect.
The femto/picoammeters and electrometers both offer 0.01 fA (10
-17
A) minimum current resolution, which
should meet most of your existing and future low-level current measurement
needs.
The electrometers feature a 1,000 V voltage sourcing capability that supports up to 10 PΩ (10
16
Ω) resistance
measurements. The electrometers also work with Keysight’s well-proven high resistance meter accessories.
The femto/picometer and electrometer/high resistance meter both have battery-powered versions that
eliminate AC power-line noise. This low-noise environment allows you to make very sensitive, low-level
measurements that were previously impossible.
Unlike conventional picoammeters and electrometers, the B2980A series features a 4.3” color LCD graphical
user interface (GUI) enabling various viewing capabilities such as numeric, graph, histogram and roll (trend
chart), which allows you to easily capture the transient behavior or to efficiently make a quick statistical
analysis without using an external PC.
This demonstration guide highlights the excellent measurement and triggering capabilities of the B2980A
series. The methodology involves sending an electronic trigger signal to a B2980A series electometer and
making a current measurement. In this example, the electrometer receives an external trigger signal with
specific timing parameters, such as 500 ms measurement delay, while sourcing 1 V across 100 GΩresistor.
