Introduction to GPIB Programming
GPIB Requirements
GPIB Requirements
Number of Interconnected Devices:
15 maximum
Interconnection Path/Maximum Cable Length:
20 meters maximum or 2 meters per device, whichever is less.
Message Transfer Scheme:
Byte serial/bit parallel asynchronous data transfer using a
3-line handshake system.
Data Rate:
Maximum of 1 megabyte per second over limited distances
with tri-state drivers. The actual data rate is the transfer rate
of the slowest device involved.
Address Capability:
Primary addresses: 31 talk, 31 listen. A maximum of 1 talker
and 14 listeners at one time.
Multiple Controller Capability:
In systems with more than one controller (like the analyzer
system), only one can be active at a time. The active controller
can pass control to another controller, but only the system
controller can assume unconditional control. Only one system
controller is allowed. The system controller is hard-wired to
assume bus control after a power failure.
