Checking cable impedance


Anyone know the best way to check interconnect impedance in a balanced cable using a multimeter?

Owl when we have a DC signal trough the cable, resistance is the big parameter. But audio is an AC signal, so we must take in account the capacitance and indutance of the cable.
The capacitance can be measured with a capacimeter. The inductance needs more work, but it can be done if you have some electrical background.
But this wont tell the impedance of the cable, because the impedance of a cable is frequency dependent because of the capacitive and inductive reactance. The impedance must be displayed graphically or it's value must be given at a certain frequency.
