A device which employs the permuting capacitors method for calibrating inductive voltage dividers (IVDs) has been fabricated. Eleven nominally equal 5 nF capacitors, having NPO ceramic as the dielectric, form the core of the device. A compact design, which is important for high frequency measurements, was realised using printed circuit-board fabrication. The eleven capacitors are fully shielded to reduce errors from stray capacitances.
