Keithley 6220 DC Current Source

The Model 6220 DC Current Source and Model 6221 AC and DC Current Source combine 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 DC power supply sourcing accuracy and built-in control functions make the Models 6220 and 6221 ideal for applications like Hall measurements, resistance measurements using delta mode, pulsed measurements, and differential conductance measurements. 6220: 100fA - 100mA Current 10n?© to 200M?© Resistance 1014?© output impedance ensures stable current sourcing into variable loads 65,536-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. Measurements are lined synchronized to minimize 50/60Hz interference.
