If the signal generator is connected directly to a computer, use a crossover LAN cable; if the signal generator is connected to a network/hub/router, do not use a cross-over LAN cable.
If you experience problems communicating with or controlling instruments over the LAN or GPIB, check the following items. If this does not solve the problem, refer to the utility Connection Expert, installed with the Agilent IO Libraries. Full information on using Connection Expert is available in the IO Libraries Suite Online Help.
Ensure that the cable and all connectors are undamaged.
Ensure that the GPIB cable is securely connected to the PC and the signal generator.
Verify that the GPIB address entered in the software matches that of the signal generator. In the software, click Instruments to view the GPIB settings.
Validate the connection. Select a signal generator connection and click Test Connection. Observe the resultant messages in the Result and Note cells to verify that the software is connecting to the signal generator.
Review the information about installing Agilent I/O libraries.

Ensure that the cable and all connectors are undamaged.
Ensure that the LAN cable is securely connected to the PC and the signal generator.
Ensure that the instrument LAN connectors are active: flashing green or yellow lights indicate LAN activity.
Verify that the Hostname or IP address entered in the software matches that of the signal generator. In the software, click Instruments to view the LAN settings.
Validate the connection. Select a signal generator connection and click Test Connection. Observe the resultant messages in the Result and Note cells to verify that the software is connecting to the signal generator.
Run the 'ping' program:
On the computer go to Start > Programs > Command Prompt (or DOS).
At
the C:\>
prompt, enter ping
<IP address>,
where <IP address> is
the signal generator's IP address.
If the signal generator does not respond, contact your IT department for help.
If the 'ping' program works correctly, but there is still a connection problem, and the PC is connected directly to the signal generator (using a cross-over cable), add the signal generator's IP address and hostname to the Hosts file, which resides at: C:\Winnt\system32\drivers\etc\Hosts.
In a text editor such as Notepad, open the Hosts file.
Write
the IP address for the signal generator and spectrum analyzer at the bottom
of the file.
(Refer to the example of a hosts file below.)
Save the file and close the text editor.

Do not use "Save As" when saving the Hosts file; this file does not have a file extension. |

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
