Abstract
A method and circuit for implementing a coded time domain transmission distance meter, and a design structure on which the subject circuit resides are provided. A first transmitter module connected to a cable at a first point or power outlet, generates and sends a testing coded pulse onto the power cable. A second receiver module connected to the cable at a second point, receives the testing coded pulse, and returns a receiver response coded pulse to the transmitter module. The first transmitter module determines the round-trip elapsed time, subtracts a receiver latency time, and calculates a distance to the second receiver module. Encoded in the testing coded pulse are data representing the last calculated distance. Both the first transmitter module and the second receiver module include a display for displaying the calculated distance.
