Abstract / Hauptanspruch
A set of respective self-configuring probe interface circuit boards (SC-MPIC's) are disclosed for use with a measurement system comprising host electronics and respective interchangeable measurement probes. Member SC-MPICs each comprises: a local circuit (LS) for probe identification, signal processing and inter-board signal control; and higher-direction and lower-direction connectors "pointing" toward and away from the measurement probe, respectively. Member SC-MPICs establish a processing hierarchy by generating lower board present signals on their higher-direction connector, higher board present signals on their lower-direction connector, and determining whether they are the highest and/or lowest SC-MPIC based on receiving those signals from adjacent SC-MPICs. They can independently perform probe identification matching operations using probe identification data from compatible and incompatible probes, and the highest SC-MPIC does this first. Member SC-MPICs advantageously pass through or isolate signals from other members in the set depending on the hierarchy, various received signals, and internal processing.
