Keithley Instruments Inc. 6220 PRECISION CURRENT SOURCE
The Keithley 6220 Precision Current Source is a low-noise, programmable DC current source designed for applications requiring precise sourcing of current from 100 fA to 105 mA. It features a voltage compliance of up to 105 V and offers high accuracy and stability for sensitive measurements. The 6220 is equipped with built-in RS-232, GPIB, and optional Ethernet interfaces for remote control and automation. Its low noise performance and fast settling time make it suitable for characterizing devices such as resistors, diodes, and transistors, as well as for use in research and development environments. The instrument supports advanced features like programmable current ramps and pulse generation, and it is compatible with Keithleys Model 2182A Nanovoltmeter for delta mode measurements, enabling high-precision resistance and material property testing.
