FAIRPORT, N.Y. – Electronics distributor Saelig Co. Inc. in Fairport, N.Y., is introducing the RBD Instruments RBD 9103 USB graphing picoammeter, a compact, versatile, general-purpose picoammeter designed to measure DC current from nanoamps to milliamps via its isolated BNC input.
This rugged portable picocurrent sensor is available with high-speed and high-voltage options, optional bias, and 5-kilovolt DC float isolation. The 9103 USB picoammeter measures bi-polar DC current and can be biased from an optional built-in fixed 90-volt DC bias, or an external low-noise DC power supply. It comes with a NIST-traceable calibration certificate.
The 9103 can take accurate current measurements from 1 picoamp to 2.499 milliamps at sample rates as fast as 500 samples per second. Its PC software interface provides control and access to functions such as data recording, and graphing.
The 9103 is also compatible with OSx, Linux, Matlab, and LabView, and can be controlled via a simple ASCII interface.
The 9103 test and measurement device is available in four models; standard with a sample rate 40 samples per second and optional 90-volt fixed or external bias; high-speed with a sample rate 500 samples per second and optional 90-volt fixed or external bias; high-voltage with a sample rate 40 samples per second with an isolated input that can float to 5 kilovolts DC; and high-speed / high-voltage with a sample rate of 500 samples per second, and can float to 5 kilovolts DC.
Designed to provide precise bipolar DC current measurements even in noisy environments such as synchrotron beam lines, the 9103 is equally suited for diode and IC I/V characterization.
With unique qualities like DC voltage isolation from chassis ground to 5-kilovolt, possibilities for researchers include direct DC current measurement of very small electron and photo multiplier signals.
Electron and ion beam measurements can be biased to reduce secondary electrons or to retard the beam as needed for experiments. The 9103 is also multi-channel capable to synchronize as many as 127 units together.
The device measures 2.11 by 6.68 by 6.3 inches, and weighs 1.5 pounds. For more information contact Saelig online at www.saelig.com.
