Keithley 4225-RPM Remote Amplifier / Switch for 4225-PMU

The Keithley 4225-RPM Remote Amplifier/Switch expands on the Keithley 4225-PMU's capabilities by providing four additional low current ranges, offering current sensitivity down to tens of picoamps. The Keithley 4225-RPM also reduces cable capacitance effects and supports switching automatically between the Keithley 4225-PMU, the Keithley 4210-CVU, and other SMU modules installed in the chassis, allowing the operator to choose the most appropriate instrument for a particular measurement task without re-cabling. 

The Keithley 4225-RPM’s high speed voltage sourcing and current measurement sensitivity make this combination well suited for CMOS device characterization, including high-k devices and advanced CMOS technologies like Silicon-onInsulator (SOI). 

The Keithley 4225-RPM combination is compatible with most semi-automatic probe stations. An optional multi-measurement performance cable kit (4210-MMPC-x) connects the Keithley 4200-SCS to a prober manipulator, simplifying switching between DC I-V, C-V, and ultra-fast I-V testing configurations. This kit eliminates the need for re-cabling, as well as maximizing signal fidelity by eliminating the measurement errors that often result from cabling errors. Versions engineered for Cascade Microtech and SUSS MicroTec probers are available. There’s also a general-purpose kit (4200-PMUPROBER-KIT) for connecting the Keithley 4225-PMU to other triaxial and coaxial probe stations.
