Setting impedance analyzer to four point measurements

[abcpt]

Hello,

As it stands, the current impedance analyzer software is made for two point measurements meaning the wavegen and the pick up electrodes occur at the same terminals. I would like to know if it is possible to change the software to perform stimulation and measurement at different pins.

Kind regards,

André

Hi @abcpt

The two and four point measurements are hardware and not software facts. The WF Impedance Analyzer can work with four point setup.
The current flow is between Wavegen and GND. You can connect the Scope 1+/2+ to DUT and 1-/2- to Resistor GND side. Such setup is also used on the IA Adapter.

Then I misunderstood the PCB schematic. I will try out! Thanks!.

Hi @abcpt

On the IA Adapter the Wavegen 1 and Scope 1+ join under the DUT socket:

This is incredibly useful. Thanks again! I really misunderstood the pins meaning.
