Keithley 4225-RPM Remote Amplifier/Switch

Overview

The optional Keithley Model 4225-RPM Remote Amplifier/Switch is designed to extend the capabilities of the Model 4225-PMU module. It provides four additional low current measurement ranges with sensitivity down to tens of picoamps, enabling characterization of ultra-low current devices and processes. The module also reduces cable capacitance effects and supports automatic switching between the 4225-PMU, 4210-CVU, and other SMU modules in the chassis.

Key Features

• Four additional low current ranges extending measurement sensitivity to tens of picoamps
• Reduces cable capacitance effects for more accurate measurements
• Automatic switching between 4225-PMU, 4210-CVU, and other SMU modules
• Seamless integration with the Model 4200-SCS system
• Eliminates need for manual re-cabling when changing measurement modules

Applications

• Ultra-low current device characterization
• Picoamp-level measurements
• Multi-module automated test systems
• Process and materials characterization requiring dynamic module switching
