I think it wiuld be helppful if you were to give *your* definition of what a signal generator with 5K output impedance means. I mean, be quantitative and say exactly what measurement would you perform that would produce 5K as the answer?
I believe I have given a conventional definition of output impedance, namely it equals the resistance of the load you have to drive in order to cause the no-load ourput voltage to drop by 50%
So what is your quantitative measurement that would allow you to determine the output impedance?

It is a voltage source with an active components as the current / voltage provider (namely tubes or transistors with some passive devices such as resistors and Xc and Xl in a closed loop circuit).

  No, I'm not asking about a narrative discussion about what is "inside the box." I'm asking what measurement you would perform, entirely "outside the signal generator box," to determine the quantitative answer for what its output impedance is.
  
  For example, what external measurement would you make in order to derermine whether the output impedance of 5K claimed by the maker was an accurate claim or not? I.e. How exactly are you defining output impedance? How would you measure it?
  
  Until you give your operational and quantitative definition of output impedance, it is not really possible to have a sensible discussion.

    Chris,
    I don't need this discussion. You can read to the beginning of this thread if you want to know why. I am not the guy started it.
    I think you'll also find the answers to your questions at the beginning of this thread.
    Thanks,
    James
