2.5.4 Cabling
The following connection configuration can ensure that the GPIB
throughput achieves optimal performance. These configurations
include the number of instruments and cable distances:
Cable lengths should be no longer than 4 meters (2 meter
lengths maximum is suggested).
The total GPIB BUS distance should be less than 20 meter.
The total number of devices must less than 15 (including
computer itself), and at least two-thrids (2/3) of the devices
are powered on.
Devices can be connected in a linear configuration, star configura-
tion, or combination the two. The following figures show both lin-
ear and star connections.
Note:
For a star connection, the total current load will be less if
there are less than three cable connections on an individual
instrument.
