Product news

Keithley Instruments, Inc., a world leader in advanced electrical test instruments and systems, today introduced its Model 6221 AC and DC Current Source and Model 6220 DC Current Source.

AC Current Source and Current Source Waveform Generator. The Model 6221 is the only AC current source on the market. Until now, researchers and engineers have been forced to build their own AC current sources. The Model 6221 provides better accuracy, consistency, reliability, robustness, and cost effectiveness than "home-made" solutions. It is also the only commercially available current source waveform generator, which greatly simplifies creating and outputting complex waveforms. Pulse widths as short as five microseconds can be programmed, and the instrument supports pulsed I-V measurements.

The Need for Precision, Low Current Sourcing. The models 6220/6221 Current Sources 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 sectors. High sourcing accuracy and built-in control functions make the models 6220 and 6221 ideal for applications such as Hall measurements, resistance measurements using delta mode, pulsed measurements, and differential conductance measurements (an increasingly common measurement for characterizing semiconductor and nanotechnology materials).
