Step 5: Programming via the 82357B
After you have connected your GPIB instrument(s) to the 82357B, the next step is
to establish communication between your PC and the instruments using
Interactive IO. After communication has been established, you can begin
programming the instruments using VISA, VISA COM, or SICL.
Establishing instrument communication
When the Keysight IO Libraries Suite is installed on your PC, an IO utility called
Interactive IO is also installed. You can use Interactive IO to verify communication
between your PC and the connected GPIB instrument(s). This section shows you
how to use Interactive IO to verify instrument communication.
1Click the IO icon on the Windows taskbar notification area.
2Right-click the instrument and click Send Commands To This Instrument to
display the Interactive IO window. For information on Interactive IO, click Help.
3*IDN?is the default command. Click Send & Read to send the identification
query to the instrument and display its reply in the Interactive IO window.
4To send other commands, click Commands> to select from a list of common
commands, or type a command into the Command: field. If you experience
timeout errors for some commands, click Options to change the timeout value.
NOTE
Once your GPIB interface has been configured in Connection Expert, if you can
see the attached GPIB instrument(s) in the Connection Expert explorer and see
their IDN string information in the detail pane then communication has been
verified. Interactive IO allows you to manually verify communication and send
specific commands to your instruments.

Introduction to IO interface configuration
An IO interface consists of a hardware interface and a software interface. The
Connection Expert utility is used to associate a unique software interface ID with a
hardware interface.
The Keysight IO Libraries Suite uses an Interface ID or Logical Unit (LU) Number
to identify an interface. This information is passed in the parameter string of the
viOpen function call in a VISA program or in the iopen function call in an SICL
program.
The Connection Expert assigns an Interface ID and Logical Unit (LU) Number to
the interface hardware, as well as other necessary configurations. Typically, the
LU Number is automatically assigned and you can ignore its setting. The LU
Number is used internally as a unique identifier. When the IO interface is
configured, you can use Keysight VISA, VISA COM, or SICL to program assigned
instruments.
Example: IO interface configuration
For example, the GPIB interface system in the Figure 1-9 consists of a Windows
PC, an 82357B USB/GPIB interface, and three GPIB instruments with GPIB
primary addresses of 3, 4, and 5, respectively. The instruments are connected via
GPIB cables.
For this system, the Connection Expert utility has assigned a VISA name of
“GPIB1” and a SICL name of “gpib1”. With these names assigned to the
interfaces, the VISA/SICL addressing is as shown in Figure 1-9.
Since unique names have been assigned by the Connection Expert, you can use
the VISA viOpen command or the SICL iopen command to open the IO paths to
the GPIB instruments as shown in the figure.
