RBD 9103 USB Picoammeter

Rugged, portable and ASCII programmable, RBD’s 9103 USB Picoammeter measures bipolar DC current from picoamps to milliamps. It can be biased with an optional built-in fixed 90 VDC bias or the user’s own low-noise DC power supply.

Suitable for use in noisy environments, the device was designed for measuring electron and ion beams as well as diode and IC I/V characterisation. It is multichannel capable — up to 127 units can be synchronised. Other features include: current measurement (2 nA to 2 mA, 0.001 nA to 2.499 mA); programmability; automatic or manual range selection; interval or single sampling; and automatic input grounding.

The product is available in four configurations: standard (40 Sa/s, optional 90 V fixed or external bias); high-speed (500 Sa/s, optional 90 V fixed or external bias); high-voltage (40 Sa/s, floats up to 5 kV DC); and high-speed/high-voltage (500 Sa/s, floats up to 5 kV DC). It is compatible with OSx, Linux, Matlab and LabView, and can be controlled via a simple ASCII interface. Data logging and graphing software is included for Microsoft Windows.

Applications include: electron and ion current measurements; photodiode current and dark current measurements (up to 127 devices at the same time); beam and particle monitoring; data logging current comparisons; leakage current testing; mass spectrometer current measurements; materials resistance testing; direct measurement of electron multiplier output (with HV option); and high resistance measurement (with HV option).
