I want to test the device ECG and EMG device I have built using AD620 with RLD. I want to build the standard electrical model of human body and electrodes to test following parameters, using signal from function generator:

1. Common mode rejection

2. Input impedance (common and differential)

3. Difference between DRL and common mode voltage at patient

4. Electrode impedance


Is there a standard setup for this?
