LAN, USB, and GPIB Interfaces 4
Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 93
Communicating Over the GPIB Interface
Device addresses are sent by the computer in the command mode to
specify who talks and who listens. Because GPIB can address multiple
devices through the same interface card, the device address passed with
the program message must include the correct interface select code and
the correct oscilloscope address.
Device Address = (Interface Select Code * 100) + Oscilloscope Address

Interface Select Code
Each interface card has a unique interface select code. This code is used
by the computer to direct commands and communications to the proper
interface. The default is typically "7" for the GPIB interface cards.
Oscilloscope Address
Each oscilloscope on the GPIB must have a unique oscilloscope address
between decimal 0 and 30. This oscilloscope address is used by the
computer to direct commands and communications to the proper
oscilloscope on an interface. The default is typically "7" for this
oscilloscope. You can change the oscilloscope address in the Utilities,
Remote Interface dialog box.
NOTE
Do Not Use Address 21 for an Oscilloscope Address
Address 21 is usually reserved for the Computer interface Talk/Listen address, and should
not be used as an oscilloscope address.
