ANSI/IEEE 488-1978 IEEE Standard Digital Interface for Programmable Instrumentation

ANSI/IEEE 488-1978 Стандарт IEEE цифровой интерфейс для программируемого Instrumentation

This standard applies to interface systems used to interconnect both programmable and nonprogrammable electronic measuring apparatus with other apparatus and accessories necessary to assemble instrumentation systems. It applies to the interface of instrumentation systems, or portions of them, in which the: (1) Data exchanged among the interconnected apparatus is digital (as distinct from analog) (2) Number of devices that may be interconnected by one contiguous bus does not exceed 15 (3) Total transmission path lengths over the interconnecting cables does not exceed 20m (4) Data rate across the interface on any signal line does not exceed 1Mb/s .
