Product Overview

The 6220 CAL D from Keithley is a DC precision current source. It 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. It is a need for precision, low current sourcing. This current source is fully programmable via the front panel controls or from an external controller via RS232 or GPIB interfaces. It can source DC currents from 100fA to 105mA. The output voltage compliance of either source can be set from 0.1V to 105V in 10mV steps. It is fully programmable via the front panel controls or from an external controller via RS-232 or GPIB interfaces.
  • Calibrated with data DC precision current source
  • 10^14ohm output impedance ensures stable current sourcing into variable loads
  • 65000 point source memory allows executing comprehensive test current sweeps directly
  • Built-in RS-232, GPIB, trigger link and digital I/O interfaces
  • Reconfigurable triax output simplifies matching the application’s guarding requirements
  • 2nA to 100mA current range (+5% over range), 100fA to 10µA programming resolution
  • 100V to 240V rms, 50 to 60Hz power supply, 120VA power consumption
  • Drop-in replacement for the model 220 current source

Model 6220 current source with line cord, Protective triax shield/cap (CAP-28-1), 237-ALG-2 triax cable terminated with alligator clips on one end, Model 8501 trigger link cable, CA-351 null-modem serial cable, Certificate of calibration, User manual, Product information CD-ROM that contains PDFs of the user’s and reference manuals.


Never place a container of liquid (example water, coffee) on the top cover. If it spills, the liquid will enter the case through the vents and cause severe damage.


When handling the model 6220, never touch the heat sink located on the right side of the case. This heat sink could be hot enough to cause burns.
