The Model 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 Model 6220 ideal for applications like Hall measurements, resistance measurements using delta mode, pulsed measurements, and differential conductance measurements. Key Features and Benefits:

Source and sink (programmable load) 100fA to 100mA

1014O 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
