Keithley Instruments Inc. 6430 SENSITIVE SOURCEMETER
The Keithley 6430 Sub-Femtoamp Remote SourceMeter® SMU Instrument is a high-precision instrument designed for sourcing and measuring extremely low currents and voltages. It offers a remote preamp configuration that minimizes noise and leakage currents, enabling accurate measurements down to the sub-femtoamp level. The 6430 provides four-quadrant operation, allowing it to source and sink both voltage and current, and features a wide measurement range from 100 fA to 100 mA and 200 µV to 200 V. It is ideal for applications such as semiconductor device characterization, insulation resistance testing, and low-leakage current measurements. The instrument includes advanced features like programmable test sequences, digital I/O, and GPIB/RS-232 interfaces for integration into automated test systems.
