9103 USB Picoammeter

Accurately Measure and Record Low DC Current

A programmable, data logging picoammeter with optional bias that can float up to ± 5 kV DC

9103 Picoammeter

Rugged, portable, affordable, and ASCII programmable, RBD's 9103 USB Picoammeter (ピコアンメータ) measures dual-polarity DC current from picoamps to milliamps. It can be biased with an optional built-in fixed +90V DC bias, or your own low-noise DC power supply.

Data Logging and graphing software is included for Microsoft Windows. The 9103 is compatible w/ OSx, Linux, Matlab, and LabView, and can be controlled via a simple ASCII interface.

The 9103 works well in noisy environments. It was designed for measuring electron and ion beams as well as diode and IC I/V characterization. The 9103 is multi-channel capable - up to 127 can be synchronized

The 9103 is Now Available in Four Configurations:

  • Standard: sample rate 40 reads/second
  • High-speed: sample rate 500 reads/second
  • High-voltage: sample rate 40 reads/second, floats up to 5 kV DC *
  • High-speed / High-Voltage: sample rate 500 reads/second, floats up to 5 kV DC *

Two Bias Options are available on the Standard and High-speed Models:

  • +90 V Fixed
  • External:  Dual-BNC input

For information about why you would use an internal or external bias, please see this blog post.

* High-voltage supply provided by user.
* Bias options not available with high-voltage version.

Actuel Data Logging and Graphing Application

Actuel is RBD’s 9103 control and data acquisition application. Actuel provides the interface to RBD’s new 9103 Picoammeter, including a control and display medium for the Picoammeter. It also includes an interface that provides data sampling and recording (data logging). In addition, the software provides a console for accessing advanced features of the Picoammeter, including calibration and diagnostics.

The latest version of Actuel is available here.
