Part 2

Appendix AINTERFACE CONCEPTSThis appendix introduces concepts for HP-IB and Serial Data (RS232C andRS4491423) interfaces used with the 3497A. It is divided into 3 parts: INTRODUC-TION TO THE HP-IB; SERIAL I10 CONCEPTS AND THE 3497A; and INTRODUCTIONTO RS232ClRS449.INTRODUCT ION TO THE HP-I6This part of Appendix A summarizes the major functions of the HP-IB. If you needmore information on HP-IB, refer to the HP-IB Abbreviated Description Manual (-hp-part number 5955-2903). A condensed description is also available in the CondensedDescription of the Hewlett-Packard lnterface Bus Manual (-hp- part number59401-90030). These manuals are available through your local -hp- Sales and ServiceOffice.The Hewlett-Packard lnterface Bus (HP-IB) is Hewlet-Packard's implementation of IEEEStandard 488-1 978, "Standard Digital lnterface for Programmable Instrumentation".HP-IB is an interface system which uses a party-line bus structure so that up to 15devices can be placed on a single bus.One controller can control up to 14 devices on a bus. For example, as shown inFigure A-1, an -hp- 85A Desktop Computer, acting as system controller, can controlup to 14 devices over the HP-IB interface bus. Of course, more than one controllercan be placed on the bus, if one of the controllers is designated as SystemController.Artisan Technology Group - Quality Instrumentation ...
