Addressing Instruments

Example: Assigning a USB Alias Name

This figure shows an example USB Devices dialog box for an Agilent

33220A. To change the USB Alias name, type the new name in the

Alias

name

box and then click the OK button. The Alias name can be used as

the preferred address for the VISA rsrcName and the SICL address.

For this example, the Alias name has been changed to

.ArbGen. from the

default

.UsbDevice1.. Thus, ArbGen can be used in viOpen() as the VISA

rsrcName parameter, rather than

.USB0::2391::1031::MY43000029::0::INSTR..

Or,

ArbGen can be used in iopen() as the SICL address parameter, rather

than the alternate address of

.usb0[2391::1031::MY43000029::0]..
