Keithley 6220   

Low Noise Precision DC Current Source  
Wth GPIB and RS-232 Interfaces


  • Source and sink (programmable load) 100fA to 100mA
  • 1014Ω output impedance ensures stable current sourcing into variable loads
  • 65,000-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
