Dear,
We used the Analog Discovery 2 to measure impedance. We did first tests using the Python API.
Now, we would like to integrate the measure directly to a PLC for process automation.
Do you propose a OEM version of the module to measure impedance which could be compatible with a PLC ?
Otherwise, we found this module: https://www.digikey.fr/fr/product-highlight/d/digilent/pmodia-impedance-analyzer
Is it possible to measure impedance at 100 Hz frequencies with that component ?
Thanks for your help.
Best regards,
Tanguy

Dear Attila, thanks for your quick reply. I understand why. So, if we want to do differential measurment, is it better to perform two measures at using a 2 electrodes set-up and substract the results ? Regards, Tanguy

Hello,
We are trying to perform differential impedance measurment with the Analog Discovery 2. It works directly from the interface but we didn't find how to select, in the API, the topology for the differential impedance (W1-C1P-DUT-C1N-C2-R-GND). We can only select two topology (0, 1 and 8). Could you help us ? If possible, do you have a code example showing how to work with this differential impedance ? Thanks !
couple coil set-up with the analog discovery 2 ?

Hello,
I am using the analog discovery 2 to perform impedance measurment and I am interested to use it to measure sugar concentrations. I found this very interesting paper with a coupled coil set-up (cf Figure 2 in the paper) which seems to work very nicely for my application:

Does anyone have already worked with this type of set-up ? Any advices ?
Thanks !
