  • Description

    • Source and sink (programmable load) 100fA to 100mA
    • 1014Ω output impedance ensures stable current sourcing into variable loads
    • 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
    • Reconfigurable triax output simplifies matching the application's guarding requirements
    • Model 220 emulation mode eliminates need to reprogram existing applications
    • Source AC currents from 4 pA to 210m A 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 as short as 5μs, 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

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

    AC current source and current source waveform generator. Model 6221 is the only low current AC source on the market. Before its introduction, researchers and engineers were forced to build their own AC current sources. This cost-effective source provides better accuracy, consistency, reliability, and robustness than “home-made” solutions. The Model 6221 is also the only commercially available current source waveform generator, which greatly simplifies creating and outputting complex waveforms.
