characteristic impedance+twisted pair+formula
I have a CAT5 cable am using it to send and receice between two transcivers through RS485.
the cable's characteristc impedance of the cable is not 120 OHM, so it doesn't match to the loads.
Now i want to maych the loads, i want to have a technique to measure the impedance of the cable.
