Abstract
An instrument system for locating leakage at a subscriber's premises is disclosed.
Claims5
An instrument system, comprising:
- a first instrument configured to be secured to a port at a subscriber's premises, the first instrument including a transmitter operable to generate and transmit signals modulated with tag signals 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 including an antenna operable to receive the signals.
An instrument system, comprising:
- a signal level meter or other test instrument;
- and
- an antenna assembly operable to:
- receive signals in multiple frequency sub-bands across a frequency range of about 100 MHz to about 1.2 GHz based on one or more switches configured to selectively connect multiple sub-band circuits, corresponding to the multiple frequency sub-bands, to at least one antenna, and
- supply the signals to the signal level meter or other test instrument, the signal level meter or other test instrument configured to scan the multiple frequency sub-bands, locate the signals, and determine a leakage amplitude and frequency based on the signals.
2 more elements
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 and transmit signals modulated with tag signals 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 with at least one antenna and locate leakage in the cable network system.
