Patent ID: 7970567

Claim:
A method for calibrating a high speed cable having boost device embedded in the cable, the cable carrying a plurality of high speed channels and a low speed control bus, the cable including an input connector and an output connector, the method comprising: (a) looping the high speed channels from the output connector to the input connector; (b) selecting a test channel from among the high speed channels; (c) selecting a sampling channel from among the remaining high speed channels; and (d) calibrating the test channel using the sampling channel: wherein the step (d) comprises: (f) selecting and setting a parameter set of the boost device; (g) testing the test channel with the selected parameter set to obtain a pulse width error indicative of the performance of the boost device; (h) selecting a different parameter set; and (i) repeating the steps (g) and (h) until the pulse width error is minimized.
