I have a RC low pass and ferrite bead cap filter combination on my circuit board. I am trying to use Audio Analyzer U8903 to analyze the gain response of the filter. I see quite different result in simulation and result using Audio analyzer.
In the audio analyzer if I change the generator impedance from 100 to 600 ohms or vice versa. I think the generator source impedance is impacting the results.
Has anyone used Audio Analyzer for filter analysis? Please let me know the methodology.
