6430
Sub-femtoamp Remote
SourceMeter® SMU Instrument
• 0.4fA p-p (4E–16A) noise
(typical)
• Remote PreAmp can be located
at the signal source to minimize
cable noise
• >1016W input resistance on
voltage measurements
• High speed — up to 2000
readings/second
• Up to 6½-digit resolution
• Fast characterization
of components with
programmable digital I/O and
interfaces
The Model 6430 Sub-Femtoamp Remote
SourceMeter SMU Instrument combines the
voltage and current sourcing and measurement
functions of Keithley’s popular SourceMeter
SMU instruments 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.
The Model 6430 makes voltage, current, and
resistance measurements at speeds no electrom-
eter can match. It can read up to 2000 source/
measure readings per second into internal memory. Currents can be measured in as little as 5ms on
the 100nA range, decreasing to just a few hundred microseconds on the higher ranges.
The Model 6430’s distinguishing features include its excellent low current sensitivity and the Remote
PreAmp, which makes this sensitivity useful by eliminating long input cables. The Remote PreAmp
is an integral part of the Model 6430’s feedback measuring system that cannot be operated indepen-
dently from the measurement mainframe, although it can be separated from the mainframe by up to
two meters of connection cable carrying high level signals.
Applications
The Model 6430’s capabilities make it equally
useful for research work and for evaluating
sophisticated components in test labs for low-
current, high-resistance, or sensitive semicon-
ductor m easurements. The low noise and drift
performance of the Model 6430 also makes it

well suited for research studies in single electron
devices, highly resistive nanowires and nano-
tubes, polymers, highly resistive nanomaterials,
and electrochemical amperometry applications.

High Speed Data Handling
The Model 6430 can read more than 2000 read-
ings per second into its internal memory buffer.
The IEEE-488 bus output can transmit up to
75 source/measure readings per second to an
external computer controller, including pass/fail
i ndication.
–100mA
The Model 6430 provides four-quadrant
sourcing of up to 2.2W, as well as measure-
ment sensitivity down to sub-femtoamp and
microvolt levels. It can measure currents
from the 1pA range (with just 0.4fA p-p noise
typical) up to the 100mA range at up to 20V.
Voltage ranges from 200mV to 200V are
available. Current and voltage range settings
define the maximum source or sink voltage
or current.
