The cable testing approaches discussed in this article gives an idea about the electrical characteristics of a coaxial cable. Velocity of Propagation, Characteristics Impedance, Return Loss Measurement and more
How to check for propoer connector installation by using a common multimeter to verify conductivity and resistance.
This useful coax tester allows you to screw the PL-259 onto the tester to get a GO/NO GO status. When the LED lights up- you have a short circuit.
This video shows one way to use a scope and function generator to measure the length of a piece of coax transmission line as well as estimate its impedance
