BEND, Ore. -- RBD Instruments Inc. announced that it has released a new version of its 9103 USB Picoammeter which incorporates faster reads per second with 5000 DC volts of isolation to chassis ground.
Increasing the DC voltage isolation from chassis ground to 5000 volts (5kV) opens up new possibilities for researchers such as 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.
To illustrate the significance of how high 5000 volts is above ground, imagine that a meter is sitting on an average tabletop and that height represents 10 volts, which is as high as some Picoammeters can float above chassis or earth ground. The new HV version 9103 would need to be mounted on the antenna on top of the Empire State building!
Designed to provide accurate bipolar DC current measurements in noisy environments such as synchrotron beam lines, the 9103 can measure from low picoamps to milliamps.
The new high speed option increases the reads per second from 40 to over 500, which is fast enough to perform optical chopper experiments. And, by taking more reads in the same amount of time as the first generation 9103 could, the accuracy is improved.
The Actuel software included with the 9103 provides new features for high speed acquisitions and display, but you can also write your own software to control the 9103 using the simple ASCII commands or in LabVIEW.
Since 9103s can be synced, it is now possible to configure a multichannel DC Picoammeter with up to 256 channels that has high speed, high voltage, or both options.
And if you do not need the high speed or high voltage options, the standard 9103 USB Picoammeter is still available as well.
