INTERFACE OPTIONS
4-1. INTRODUCTION
This section provides information on using interface Options 101, HP-1B interface, and 102,
Handler interface.
4-2. OPTION 101 HP-IB INTERFACE
4-2-1. HP-IB INTERFACE
You can use the HP 4278A's installed option 101 can be controlled via the easy to use, high
performance HP-IB bus which links the 4278A to other instruments, desktop computers, and
minicomputers to form an automated measurement system. HP-lB is Hewlett-Packard's
implementation of IEEE Standard 488-1978, IEEE Standard 728-1982, Digital Interface for
Programmable Instrumentation.
4-2-2. HP-113 CONNECTION
With the HP-1B Interface system, up to 15 HP-113 compatible instruments can be intercon-
nected (see Figure 4-1). The HP 10833 HP-IB cables have back to back male-female con-
nectors on each end so several cables can be connected to a single source without using
special adapters or switch boxes. System components and devices can be connected in
virtually any configuration as long as a path exists between each device and the controller.
If too many connectors are stocked together, their weight can produce sufficient leverage to
damage the connector mounting. Be sure that each connector is screwed firmly in place to
keep it from working loose during use. The HP 4278A uses all of the available HP-115 lines;
therefore, damage to any connector pin will adversely affect HP-IB operation. See Figure 4-
