Ok Here is my situation. I have 3 SWR meters and they all give me different readings on the same setup. Two of then are the single needle ones that you "calibrate" and then measure, the other one is a cross needle one. The cross needle one was 3x more expensive but does that mean that it is calibrated properly? I can believe that it is more accurate than the other two and that it has nicer parts inside, but I am at a point that I feel like i need to calibrate it myself and know that it is telling me the truth. (I spend a lot of time letting this annoy me lately)
So my question is how do i calibrate it?
I assume that I need a signal generator and some way of amplifying the signal to the wattage I am looking for? And that this will take care of the FWD side?
But then do i have a second singal generator amplified so i can precisely control the reflected side?
Any help on this would be great, or any point in the right direction....
