From the project

Impedance analyzer board for versatile, high-speed, and distributed sensor measurement

This repository includes the software, firmware, and hardware for the readout electronics used in the paper:

The Client subfolder contains the source code for the PC client, written in Python. The client allows connection to the FPGA and optional logging of data. The data can be interpreted in a variety of formats, such as: - raw: raw ADC counts (32-bit signed integer) - iq: impedances expressed as in-phase and quadrature components (equivalently, real and imagingary impedance components) in Ohms. - magphase: impedances expressed as magnitude (in dB) and phase (in degrees). - RCseries…
