Current Sources for Superconductor Industries

Highly precise general purpose and high performance options

Our precision current sources include both broad-purpose and high-performance options for a variety of applications. They are in test environments including R&D and production in the semiconductor, nanotechnology, and superconductor industries. Their high sourcing accuracy and built-in control functions make them ideal for Hall Effect measurements, resistance measurements using delta mode, pulsed measurements, and differential conductance measurements. Programmable pulse widths limit power dissipation in delicate components and support pulsed I-V measurements. Offering superconductor industries a powerful competitive advantage over precision, Model 6220 and similar current sources, is a reliable current source for companies experiencing low-output and low sourcing.
