Instrument, system, and method for locating a leakage source

Abstract

An instrument system for locating leakage at a subscriber's premises is disclosed.

1 . An instrument system, comprising:
 a first instrument configured to secured to a port at a subscriber's premises, the first instrument including a transmitter operable to generate in a number of different frequency sub-bands across a frequency range of about 100 MHz to about 1.2 GHz, and   a second instrument include an antenna operable to receive the signals.   
     
     
         2 . The instrument system of  claim 1 , wherein the second instrument includes a signal level meter coupled to the antenna, the signal level meter being operable to scan the frequency sub-bands, locate the signals, and determine a leakage amplitude and frequency. 
     
     
         3 . The instrument system of  claim 1 , wherein the antenna includes a monopole antenna and a loop antenna. 
     
     
         5 . An instrument system, comprising:
 an antenna assembly operable to receive signals in multiple frequency sub-bands and supply those signals to a signal level meter or other test instrument to scan the multiple frequency sub-bands, locate the signals, and determine a leakage amplitude and frequency based on the signals.   
     
     
         6 . A method of locating leakage in a cable network system, the method comprising:
 energizing a first instrument secured to a port at a subscriber's premises to generate in a number of different frequency sub-bands across a frequency range of about 100 MHz to about 1.2 GHz, and   operating a second instrument to receive the signals and locate leakage in a cable network system.
