Patent ID: 7592816

Claim:
A cable fault analyzer having a plurality of detection and capture circuits coupled to a plurality of antennas in a Localizer antenna array, each said detection and capture circuit comprising: a. A digital latch circuit comprising: i. a first input, ii. a second input coupled to a monitoring terminal on said Localizer antenna array, and iii. an output; b. A reset switch comprising: i. a common terminal coupled to said first input of said latch circuit, ii. a normally closed terminal coupled to a voltage source to apply a predetermined voltage to bias said latch circuit into a detection and capture mode, and iii. a normally open terminal coupled to ground to apply ground to reset said latch circuit; c. An indicator device coupled to said output of said latch circuit to signal the detection and capture of a fault in an antenna in said Localizer antenna array; and d. A buffer circuit coupled between said second input on said latch circuit and said monitoring terminal on said Localizer antenna array.
