Product Highlights

The 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 sourcing accuracy and built-in control functions make the 6221 ideal for applications like Hall measurements, resistance measurements using delta mode, pulsed measurements, and differential conductance measurements.

  • Source and sink (programmable load) 100fA to 100mA
  • 65000-point source memory allows 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
  • Source AC currents from 2pA to 100mA for AC characterization of components and materials
  • The 6221's 10MHz output update rate generates smooth sine waves up to 100kHz
  • Built-in standard and arbitrary waveform generators with 1mHz to 100kHz frequency range
  • Applications include use as a complex programmable load or sensor signal and for noise emulation
  • Programmable pulse widths limiting power dissipation in delicate components
  • Supports pulsed I-V measurements down to 50µs when used with Model 2182A Nanovoltmeter
  • Built-in Ethernet interface for easy remote control without a GPIB controller card
