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 (limited to 600 VDC)

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.

  • Optional 5 kV DC Isolation
  • Optional High-speed Sampling: 500 reads/sec.

 

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.

9103DBPR External Bias Option - with dual BNCs on the front panel of the 9103.
The 9103 floats on the customer’s ground-referenced DC voltage source.
This is the most common external bias option as most voltage sources are reference to ground (not isolated).
9103EXTBIASPR External Bias Option - with BNC connector on back panel of 9103.
The BNC connector on the back of the 9103 connects to the customer’s voltage source,
which needs to be isolated from ground (floating).
