How do I determine the output impedance?
load the output with, say, 100k measure the volatge; load the output with, say, 10k measure the volatge, then by using resistor divider math, you can get very close. The reason for 'close' is thet the output impedance may not be totally linear. If you get about the same in the above, try 10k and 1k.


Same question to you as I asked Per above
