Example: Addressing GPIB Instruments Using VISA/SICL
This figure shows example VISA and SICL addressing for GPIB
instruments connected to a PC via a GPIB interface.
The GPIB interface system consists of a Windows PC with two 82350
GPIB cards connected to three GPIB instruments via GPIB cables. For
this system, Connection Expert has been used to assign GPIB card #1 a
VISA interface ID of “GPIB0” and a SICL interface ID of “gpib0”.
Connection Expert has also been used to assign GPIB card #2 a VISA
interface ID of “GPIB1” and a SICL interface ID of “gpib1”. With these
names assigned to the interfaces, the VISA/SICL addressing is as shown
in the figure.
