Patent ID: 8922298

Claim:
A cable emulator configured to electrically emulate a cable, the emulator comprising: an input port configured to receive an signal; a first transmission line connected to the input port; a filter, the filter comprising: at least one resistor in parallel with at least one inductor, the at least one resistor and the at least one inductor connected to the first transmission line; and at least one first capacitor connected to the at least one resistor; at least one second capacitor connected to the at least one inductor, wherein a physical dimensions of at least one first capacitor is the same as the physical dimensions of at least one second capacitor and the at least one first capacitor is symmetric to the at least one second capacitor about a central axis defined by the first transmission line and a second transmission line; the second transmission line connected to the at least one first capacitor and the at least one second capacitor; and an output port connected to the second transmission line.
