ABSTRACT:
Multi-channel measurement equipment identifies probe-to-channel correspondence by providing an identification (ID) terminal that can be touched by a probe whose channel correspondence is sought. A ID signal identifiable by its uncommon properties is present at the ID terminal. The uncommon ID signal is generated by a suitable circuit, which may be similar to pseudo random sequence generator. Each channel is equipped with a recognition circuit that recognizes the presence of the uncommon ID signal. The recognition circuits each receive a copy of the uncommon ID signal, and the task of recognition is performed by pattern matching over time. To discover a probe's channel identity the operator touches the probe to the ID terminal. After a suitable but brief period of time the recognition circuit for that probe produces an output that indicates recognition. The measurement equipment may display a message on a screen to the effect that the system has noticed that the probe for channel "X" is on the ID terminal.
