Identifying A Signal On A Printed Circuit Board Under Test
First Claim
1. A method of identifying a signal on a printed circuit board (‘
- PCB’
) under test, the method comprising;
transmitting a test signal from a test signal generator of an integrated circuit mounted on the PCB to an output pin of the integrated circuit, the output pin connected to a test point on the PCB;
inserting, by signal identification logic of the integrated circuit into the test signal, an identifier of the signal;
receiving, by a signal-identifying controller from a test probe in contact with the test point, the test signal and the identifier;
displaying, by the signal-identifying controller in dependence upon the identifier, the identity of the signal.

Abstract
Apparatus and methods for identifying a signal on a printed circuit board (‘PCB’) under test, including an integrated circuit mounted on the PCB, the integrated circuit having a test signal generator that transmits a test signal to an output pin of the integrated circuit, with the output pin connected to a test point on the PCB; the integrated circuit also having signal identification logic that inserts into the test signal, an identifier of the signal; a test probe in contact with the test point; and a signal-identifying controller that receives the test signal and the identifier from the test probe and displays, in dependence upon the identifier, the identity of the signal.
