Principle

The coil is connected in a circuit with a voltage source of variable frequency. The impedance and phase displacements are determined as functions of frequency. Parallel and series impedances are measured.

Benefits


Intuitive, touch-optimized software that controls all devices simultaneously

Simplified implementation: all pre-settings already prepared

Easy frequency setting thanks to digital function generator

Fast and easy experimenting simply by switching components

Impedance will be computed in real-time

Further experiments in electricity and electronics can be performed with the equipment
