Key features

• •Source and sink (programmable load) 100fA to 100mA. Model 220 emulation mode eliminates need to reprogram existing applications.
• •1014? output impedance ensures stable current sourcing into variable loads. 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.
• •65000-point source memory allows executing comprehensive test current sweeps directly from the current source. 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
• •Built-in RS-232, GPIB, Trigger Link, and digital I/O interfaces. Programmable pulse widths as short as 5-s, limiting power dissipation in delicate components. Supports pulsed I-V measurements down to 50?s when used with Model 2182A Nanovoltmeter
• •Reconfigurable triax output simplifies matching the application's guarding requirements. Built-in Ethernet interface for easy remote control without a GPIB controller card
