The Pmod IA is no longer in production. Once the current stock is depleted, it will be discontinued.

As much as we love this product, we have had to shift resources to developing and supporting our other state-of-the-art products for our customers. Therefore, future support, through our technical support forum, will no longer be available for the Pmod IA. Please only purchase the Pmod IA if you feel comfortable with the technology it utilizes. Digilent’s standard return policy will still apply.

The Digilent Pmod IA 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 impedance ranging from 100Ω - 10MΩ. By communicating with the Pmod through the I²C interface, users may program the Pmod to perform a frequency sweep across a circuit in order to calculate the impedance.
