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 DC power supply 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
- 1014R output impedance ensures stable current sourcing into variable loads
- 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
