Hi attila , Thanks for the response. Calling configure after changes works well as per expectation. However I did't see a change with dwf.FDwfAnalogImpedanceStatus(hdwf, None). Here is a snippet of the code so if I add the following line to the code, i get the expected 2nf as output, but if I # block the line it throws some numbers other than the expected 2nf. dwf.FDwfAnalogImpedanceConfigure(hdwf, c_int(1)) looking at the results I am not quite sure if making impedance status as "None" made a difference. Kindly let me know incase if my use case of dwf.FDwfAnalogImpedanceStatus(hdwf, None) is wrong. Thanks!

Hi, I want to understand how the command analongimepedanceconfigure works with respect to changes made to let’s say impedance amplitude or frequency set changes. The context of the query: I had a simple circuit, the DUT being a 2 nano farad and a reference resistor to ground. I was passing a list of frequencies through impedance frequency set command. If I don’t apply impedanceconfigure after the change in frequencies, I got some random numbers for capacitance(not 2 nf) but I got ~2 nf if I apply impedanceconfigure after every change in frequencies through the frequency set. BTW what number will AD2 throw if I change frequency set without impedanceconfigure. Thanks!
