Source AC currents from 4pA to 210mA peak to peak for AC characterization of components and materials The 6221’s 10 MHz output update rate generates smooth sine waves up to 100 kHz Built-in standard and arbitrary waveform generators with 1 mHz to 100 kHz 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 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 Instrument control software available for both Macintosh and PC controllers Applications: Nanotechnology: Differential conductance, Pulsed sourcing and resistance Optoelectronics: Pulsed I-V Replacement for AC resistance bridges (when used with Model 2182A) Measuring resistance with low power Replacement for lock-in amplifiers (when used with Model 2182A) Measuring resistance with low noise The Keithley 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.
