Description

643071-7 is a rectangular connector accessory that belongs to Keithley’s Model 6430 Sub-Femtoamp Remote SourceMeter SMU Instrument series. This type of instrument combines the voltage and current sourcing and measurement functions of SourceMeter SMU instruments with sensitivity, noise, and input resistance specifications superior to electrometers.

Specifications and Features

• 0.4 fa p-p (4E-16a) noise (typical).
• Remote Preamp that can be located at the signal source to minimize cable noise.
• More than 1016 ohms input resistance on voltage measurements.
• High speed, up to 2000 readings/second.
• Up to 6 1/2-digit resolution.
• Fast characterization of components with programmable digital I/O and interfaces.

Application Scenarios

Model 6430 is a suitable instrument for applications that require both voltage and current sourcing and measurement functions, coupled with high sensitivity, noise immunity, and input resistance. Its most relevant usage scenarios include materials research, nanotechnology, and quantum physics experiments, as well as characterization of sensitive electronic components or devices.

Comparison

• Combines comprehensive measurement and sourcing functions.
• Remote Preamp minimizes cable noise.
• High sensitivity, noise immunity, and input resistance.
• Fast characterization of components.
• Programmable digital I/O and interfaces.

• Designed for specific applications that require high sensitivity features, typically for scientific research or development purposes, making it less suitable for general engineering tasks.
