The Keithley 6220 DC Current Source combines ease of use with exceptionally low current noise. Low current sourcing is critical to applications in test environments ranging from R&D to production, especially in the semiconductor, nanotechnology and superconductor industries. High sourcing accuracy and built-in control functions make the 6220 ideal for applications like Hall measurements, resistance measurements using delta mode, pulsed measurements and differential conductance measurements.
Features
- Source and sink (programmable load) 100fA to 100mA
- 1014 ohms output impedance ensures stable current sourcing into variable loads
- 65000-point source memory allows executing comprehensive test current sweeps directly from the current source
- Built-in RS-232, GPIB, Trigger Link, and digital I/O interfaces
- Reconfigurable triax output simplifies matching the application's guarding requirements
- Model 220 emulation mode eliminates need to reprogram existing applications
- Instrument control software available for both Macintosh and PC controllers
