FAQ

The GI2K Series is a precision high AC current source designed to deliver accurately controlled, stable AC current for applications where current accuracy and repeatability are critical.

Precise current control is essential when:

DUT performance depends directly on current

Small current deviations affect results

Repeatable and traceable measurements are required

Calibration and validation accuracy is critical

As a current‑controlled source, the GI‑2K Series continuously regulates output to maintain the programmed AC current, even if the DUT impedance changes during operation.
