Hello!
I have a problem with finding out the impedance of a transmission line.
Im working on a project and i need to find out a way how to calculate(find out) the impedance of a given line not using time domain reflectometry.
What measurements i have to do to find out the impedance using only frequency domain?
The frequency range is from 100khz-2Ghz.
Im out of ideas, any smarter people out there?
What kind of measurement instruments do you have available?
You can terminate the transmission line with a resistor in the range of the expected transmission line impedance and measure the input impedance versus frequency. ZL can be determined from the observed minimal and maximal impedance input impedance.
