The invention comprises a phase locked loop that has an input adapted to receive a reference frequency. According to one embodiment, the system includes a disk drive carrier cage configured to receive a disk drive backplane and up to eight pair of disk drive carrier rails. Using these timing signals, the location of the television receiver may be determined Based on a comparison between a stored, expected location of the television receiver and the determined location, the functionality of the television receiver may be adjusted. A conclusion is drawn as to the presence of a leak in the vessel by comparing the results of the leak-tightness measurement and the reference measurement.
