Hello, my name is Jinhwan Kim from south korea. Now, I have experimented getting impedance with AD5933.

 

 

My experiment was that after I was testing with AD5933, I compared this result with Gamry. As you know that this device has output frequency range from 1 khz to 100khz.

 

However, impedance from AD5933 wasn’t matched with Gamry. Specifically, I couldn't get the suitable impedance down to 5khz with resistor. In case of the capacitor, I also couldn't get the impedance down to 12khz.

 

I would like to know whether my device has problem or not. And then, I also want to know that I can’t get the impedance down to 12khz with capacitor.
