8.4 GPIB Interface
This section will introduce the GPIB bus standards, connection methods, and some settings of the
instrument. This section only applies to GPIB models: 5492CGPIB and 5493CGPIB.
8.4.1 GPIB Bus
IEEE488 (GPIB) is an international bus interface standard used on intelligent instruments. IEEE is the
English abbreviation of Institute of Electrical and Electronics Engineers, and 488 is the standard
number. Multiple test instruments can be connected simultaneously on the same bus. This instrument
adopts the IEEE488.2 standard. The control command system is open so that the user can use the PC
operation interface provided by 5492CGPIB/5493CGPIB or take measurements by the control
command system. The control command system supports most functions of the instrument, that is to
say, the user can execute almost all operations on PC.
When configuring a GPIB system, the following restrictions must be adhered to.
1
．
The total length of cable in one bus system must be less than or equal to two meters times the
number of devices connected on the bus (the GPIB controller counts as one device) and the
total length of cable must not exceed 20 meters.
2
．
A maximum of 15 devices can be connected to one bus system.
3
．
There are no restrictions on how the cables are connected together. However, it is
recommended that no more than four piggyback connectors be stacked together on any one
device.
