I want to ask if it is correct
to measure Op-Amp output impedance by measuring S22 with Network Analyzer

The answer is yes,
but just be sure you do not exceed the DC voltage input level to the

I agree with Brad. just wanna add, probably it's safer
to use attenuator at the port 2 of network analyzer.

made in the previous responses is that you want the closed-loop output
impedance (of the entire circuit), not the intrinsic output impedance
of the operational amplifier (by itself).
Is this a correct assumption?
