Hp-Ib System Interface Connections - HP 3326A Installation Manual

HP-IB Interface Connections
HP-IB SYSTEM INTERFACE CONNECTIONS
The HP 3326A instrument is compatible with the Hewlett-Packard Interface Bus (HP-IB),
The HP-IB is Hewlett-Packard's implementation of IEEE Standard 488-1978 and ANSI
Standard MC 1.1. The HP 3326A is connected to the HP-IB by connecting an HP-IB
interface cable to the connector located on the rear panel. Figure 9 illustrates a typical
HP-IB system interconnection.

Figure 9. Typical HP-IB System Interconnection
With the HP-IB system, up to 15 HP-IB compatible instruments can be interconnected.
The HP 10833 HP-IB cables have identical piggy-back connectors on each end so that
several cables can be connected to a single source without special adapters or switch
boxes. System components and devices can be connected in virtually any configura
tion. There must, of course, be a path from the controller to every device operating
on the bus. As a practical matter, avoid stacking more than three or four cables on
any one connector. If the stack gets too long, any force on the stack can damage the
connector mounting. Be sure that each connector is firmly screwed in place to keep
it from working loose during use (see CAUTION in Figure 10). The HP 3326A uses all
the available HP-IB lines, therefore, any damaged connector pins may adversely affect
HP-IB operation. Refer to Figure 10 for a description of the HP-IB connector.
