Keithley 4225-RPM Remote Preamplifier/Switch Module

Remote Preamplifier/Switch Module

The optional Model 4225-RPM Remote Amplifier/Switch expands on the Model 4225-PMU’s capabilities by providing four additional low current ranges, offering current sensitivity down to tens of picoamps. The Model 4225-RPM also reduces cable capacitance effects and supports switching automatically between the Model 4225-PMU, the Model 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.
