Programming Over HP-IB
2
Introduction This section describes the interface functions and some general concepts
of the HP-IB. In general, these functions are defined by IEEE 488.1
(HP-IB bus standard). They deal with general bus management issues, as
well as messages which can be sent over the bus as bus commands.

Capabilities
The interface capabilities of the HP 1650B/51B, as defined by IEEE 488.1
are SHl, AHl, T5, TEO, L3, LEO, SRl, RLl, PPl, DCl, DTl, CO, and E2.
Command and
The HP-IB has two modes of operation: command mode and data mode.
Data Concepts
The bus is in command mode when the ATN line is true. The command
mode is used to send talk and listen addresses and various bus commands,
such as a group execute trigger (GET). The bus is in the data mode when
the ATN line is false. The data mode is used to convey device-dependent
messages across the bus. These device-dependent messages include all of
the instrument commands and responses found in chapters 5 through 9 of
this manual and in the individual programming manuals for each module.
