DC Precision Current Source. Unit sold with a valid calibration certificate and with 12 months warranty.

The Model 6220 is a DC Current Source and 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 DC power supply sourcing accuracy and built-in control functions make the Model 6220 ideal for applications like hall measurements, resistance measurements using delta mode, pulsed measurements, and differential conductance measurements.
