Greetings, Quite interesting project. Looks like you need a working PCB design which will have AD5934 along with a uC to control this Impedance analyzer IC. You also would need some kind of interface to communicate the data over to your PC/Mobile or store it in a SD card to do something useful out of it. I have good expertise with Analog Circuits, uC, USB/Serial/BLE interfaces, PCB design, Embedded systems. Please see my profile for details. I think I can deliver this end to end to you. However it would be good if we can discuss the details of the 4 terminal spectroscopy and how would you like the interfacing to be done. Look forward to hear from you. T & R Alok Pugalia

Hello my Name Is Carlos. I am an electrical engineer, I belong to the mentioned electronic and communications. I understand from your project that you want to have a device similar to a VNA but that it measures impedance at a lower frequency. I imagine that you expect as output an impedance matrix Z. The work plan that I visualize is to use some AD5934 or Use one with a multiplexer. Your project looks interesting, I have the knowledge, the tools and the time to do your project. At the moment I am developing like professional in the design of products or electronic devices, along with a group of colleagues engineers. If you are interested, you can write to me with confidence.

Hello, I can do this work for you. Please, send me more information. AD5934 is designed to measure impedance 1 kilohms to 10 megohms, from 100 ohms to 1 kilohms with additional circuit. Under these resistances four-wire connection method does not gain in precision. If you want to measure small resistance need another chip. I develop concepts, design circuit, PCB and software for devices on Microchip and Atmel microcontrollers (C, C++, Arduino). You can see some my works in my portfolio. Regards, Alexey
