Keithley 6430 Sub-Femtoamp Remote SourceMeter
The Model 6430 Sub-Femtoamp Remote SourceMeter combines the voltage and
current sourcing and measurement functions of Keithley's popular SourceMeter
and Source-Measure Unit (SMU) products with sensitivity, noise, and input
resistance specifications superior to electrometers. This unique combination of
broad functionality and exceptional measurement integrity is made possible by
the Model 6430's Remote PreAmp, which offers a very sensitive bi-directional
amplifier with sensitive feedback elements for measuring or sourcing currents
at the device being tested. The high level signals output by the Remote PreAmp
are sent to the controlling mainframe via a two-meter cable. This allows the
user to make a direct or very short connection to the signal, minimizing the
effects of cable noise.
Key Features and Benefits:
0.4fA p-p (4E-16A) noiseRemote PreAmp can be located
at the signal source to minimize cable noise>1016Ω input resistance on
voltage measurementsHigh speed - up to 2000
readings/secondUp to 6-1/2-digit resolutionFast characterization of
components with programmable digital I/O and interfaces
