When I turn my sig.gen on(square wave) and feed that signal into my power meter (50 Ohms load true r.m.s.), my meter says my square wave has the same power at 100Hz as it has at 100KHz,200KHz,300KHz...

But we are not talking about square waves but short pulses. Get a signal generator and set it to produce a 1uS wide pulse. Now set the repetition rate to 10KHz and connect it to your rms meter, then repeat at 100KHz and see how the power varies.

                        Hi Terry, thanks for the input....            01/01/70 00:00      
                           what has that to do with the subject you raised            01/01/70 00:00

                  Hello Ian            01/01/70 00:00      
            Mr OHM and MR AMPERE laws violated??            01/01/70 00:00      
               No, I have better things to do.            01/01/70 00:00      
                  let me try, not that I think it will do any good            01/01/70 00:00

         one example please of a non-historic device            01/01/70 00:00      
      never seen that            01/01/70 00:00      
   Let's try this            01/01/70 00:00
