Instrumentation: Insight into interfacing: Thorough and unambiguous understanding of interface systems demands sound design concepts and a precise descriptive language

An interface system definition, one optimized for the interconnection of programmable bench instruments, must contain many vital communication capabilities if it is to interconnect independently manufactured products at reasonable costs. It must also maintain a high level of compatibility, and a high degree of flexibility. The specific objectives of such an interface system, along with the basic feasibility criteria, were presented in the November 1974 issue of Spectrum (pp. 52-57).
