Keithley 6221 AC and DC Current Source

The Keithley 6221 AC and 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 The 6221 is 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 executing comprehensive test current sweeps directly from the current source
• Built-in RS-232, GPIB, Trigger Link, and digital I/O interfaces
• Source AC currents from 4pA to 210mA peak to peak 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.
