Abstract:
1. A method of identifying a signal on a printed circuit board (‘PCB’) under test, the method comprising: transmitting a radio signal from a test probe, the test probe comprising a radio transmitter and transmitter antenna, the test probe positioned with the transmitter antenna at a test point on the PCB; receiving the transmitted radio signal by at least two radio receivers, each receiver comprising a receiver antenna, each receiver antenna positioned at predetermined, separate physical locations with respect to the PCB, the receivers coupled to at least one signal strength meter; reading, by a signal-identifying controller from the at least one signal strength meter, signal strengths of the transmitted radio signal as received at the radio receivers, the signal-identifying controller comprising a module of automated computing machinery; determining, by the signal-identifying controller in dependence upon the read signal strengths, a test signal identifier, wherein the signal-identifying controller further comprises a list of signal strengths associated with test signal identifiers, and determining a test signal identifier further comprises looking up, by the signal-identifying controller in the list, a test signal identifier; and displaying, by the signal-identifying controller, the test signal identifier.
