Not! The source plays no role at all. The degree of match that is indicated is that between the line (or system Zo) and the load Z. A 50 ohm instrument with a 50 ohm termination shows a reflection coefficient (or whatever mathematical equivalent you want to use) of zero regardless of the source impedance. |So let's call it a TLI. Let's don't. That's just more bafflegab. Suppose the source impedance is 25 ohm and the load is 50 ohm. By this new monstrosity of a definition, the source should be delighted when the "transmitter loading indicator" says---well---I'm not sure what it says, but I think the desired number is either 0 or 1. And another source (transmitter) with a source Z of 100 ohm should be equally happy. Right? |Which is what it actually is. Abolish |the source of confusion and the arguments on what it does. I'm all for abolishing the confusion too, so why did you add to it? |
