Programming Your Instruments
Since unique names have been assigned by Connection Expert, you can
use the VISA viOpen command to open the I/O paths to the GPIB
instruments as shown in this figure. Or, you can use the SICL iopen
command to open the I/O paths shown.
Addressing Instruments via USB
As desired, you can use a VISA alias to address instruments via USB.
The VISA alias associates a symbolic name with a specific instrument.
You can use it as a VISA rsrcName or SICL address instead of using the
full address (or resource descriptor), which may include the
instrument’s vendor ID, product ID, serial number, and interface ID, etc.
See the following steps to set, add, delete or change a VISA alias.
