Product Overview

The Model 6220 DC Current Source and Model 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 Models 6220 and 6221 ideal for applications like Hall measurements, resistance measurements using delta mode, pulsed measurements, and differential conductance measurements.

Features	Benefits
10₁₄Ω output impedance	Ensures stable current sourcing into loads with a wide range of output impedances.
65000-point source memory	Allows executing comprehensive test current sweeps directly from the current source.
Output voltage compliance from 0.1V to 105V in 10mV steps	Prevents 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 output	Simplifies matching the application’s guarding requirements.
