주요기능
•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 triaxoutput 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 as short as 5s, limiting power dissipation in delicate components. Supports pulsed I-V measurements down to 50μs when used with Model 2182A
