This thesis describes the setting up and running of two individual systems for calibration of low current equipment to accuracy of 100 fA and below. The Differentiating Capacitor Current Source System calibrates equipment of the range 1 pA to 100 pA, whereas the Voltage-Resistor Source System calibrates equipment of the range 100 pA to 10 nA.
