6430 Sub-femtoamp Remote SourceMeter® SMU Instrument |
| 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.
Key Feature
Applications The Model 6430’s capabilities make it equally useful for research work and for evaluating sophisticated components in test labs for lowcurrent, high-resistance, or sensitive semiconductor measurements. 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 nanotubes, polymers, highly resistive nanomaterials, and electrochemical amperometry applications. |
| 6514 Programmable Electrometer |
| The Model 6514 Electrometer combines flexible interfacing capabilities with current sensitivity, charge measurement capabilities, resolution, and speed that are equal or superior to our earlier electrometers. The Model 6514’s built-in IEEE-488, RS-232, and digital I/O interfaces make it simple to configure fully automated, high speed systems for low-level testing.
The 5½-digit Model 6514 is designed for applications that demand fast, yet precise measurements of low currents, voltages from high resistance sources, charges, or high resistances. Key features

6517B Electrometer/High Resistance Meter |
The Keithley 6517B Electrometer/High Resistance Meter is the worldwide research laboratory standard for sensitive measurements. With over 60 years of low level measurement expertise, Keithley electrometers provide reliable measurements of current levels down to 10 aA (10×10–18 A), charge levels down to 1 fC, and the highest resistance measurements available up to 1018 Ω. The 6517B is also capable of measuring the largest voltage range—up to 200 V—with an input impedance exceeding 200 TΩ. All this performance is built into an instrument that operates as simply as a digital multimeter.
