Keithley 6200 Ultra-sensitive Current Sources Series Product Description



1014Ω output impedanceEnsures stable current sourcing into loads with a wide range of output impedances.
65000-point source memoryAllows executing comprehensive test current sweeps directly from the current source.
Output voltage compliance from 0.1V to 105V in 10mV stepsPrevents potential damage to devices susceptible to overvoltage.
Source AC currents from 4pA to 210mA peak to peak (6221)Supports AC characterization of components and materials.
10MHz output update rate (6221)Generates smooth sine waves up to 100kHz.
Built-in standard and arbitrary waveform generators with 1mHz to 100kHz frequency range (6221)Supports use as a complex programmable load or sensor signal and for noise emulation.
Programmable pulse widths as short as 5μs (6221)Limits power dissipation in fragile, low power components and supports pulsed I-V measurements down to 50μs when used with the Model 2182A Nanovoltmeter.
Reconfigurable triax outputSimplifies matching the application’s guarding requirements.
