Identifying a signal on a printed circuit board (‘PCB’) under test, including a test probe with a radio transmitter and transmitter antenna, the test probe positioned with the transmitter antenna at a test point on the PCB, the test probe transmitting a radio signal; at least two radio receivers, each receiver having 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, each receiver receiving the transmitted radio signal; and a signal-identifying controller connected to the signal strength meter, the signal-identifying controller reading, from the signal strength meter, signal strengths of the transmitted radio signal as received at the radio receivers; determining, in dependence upon the read signal strengths, a test signal identifier; and displaying the test signal identifier. |
