The Digilent PmodIA provides users with a way to measure the electrical impedance of a circuit. It is powered by the Analog Devices AD5933, a high-precision impedance converter system solution that combines an on-board frequency generator with a 12-bit, 1 MSPS, analog-to-digital converter (ADC). The two SMA connectors provide easy access to the AC voltage output and the incoming frequency response allowing users to measure impedances ranging from 100 Ω to 10 MΩ.
