Keithley Instruments 6220 Overview

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
