Abstract
A digital toner/locator employs tone packets using a 455 Khz carrier. Plural packet quanta provide multiple test modes which are advantageously selected from a probe without requiring returning to the tone generator to change mode.
Claims33
A toner/probe system, comprising:
- a toner adapted to generate and supply a tone packet to a cable under test, wherein said toner supplies a carrier signal as at least part of said tone packet;
- and
- wherein said tone packet comprises:
- a synchronization portion;
- and
- a data portion.
3 more elements
A method for locating a cable, comprising the steps of:
- applying a tone packet to a cable at one position thereof, wherein said tone packet employs a carrier signal as at least part of said tone packet;
- and
- employing a sensor responsive to said tone packet to locate said cable at another position thereof,
- wherein said applied tone packet comprises:
- a synchronization portion;
- and
- a data portion.
4 more elements
A toner/probe system, comprising:
- a toner adapted to generate and supply a tone packet to a cable under test, wherein said toner supplies a carrier signal as at least part of said tone packet;
- and
- a probe adapted to detect said tone packet as propagated via the cable under test
- wherein said tone packet comprises:
- a synchronization portion;
- and
- a data portion.
