Default I want to test regulator output impedance!! How to setting AP2722?

I have to use the super regulator circuit!
I want use the AP2722 to test the performance of super regulator.
But I don't know how to setting AP2722?
I want to test output impedance and LR and noise!!
thank you!!

Have you tried the manual and their applications support? This is a complicated piece of equipment, and it would cost me much time to guide you through all the details.

I know how to seting the LR and noise test.
But i don't know how to setting of impedance test.
Analog analyzer should be choice which?
Bandpass or band reject , THN or other.
Whether should be to select FFT??

I think your problem is more related to the basic impedance measurement rather than the operation of the SYS-2722. Basically you inject a current and measure resulting voltage drop, which by Ohm's law can be referred back to impedance. How you measure the voltage depends on many variables--usually it is a small voltage so you use a narrow band measurement.
