Verify that the GPIB cable and all connectors are undamaged.
Verify that the GPIB cable is securely connected to the PC and the signal generator.
Verify that the instrument you are trying to communicate with is turned on.
Verify that the GPIB address entered in the software matches that of the signal generator. In the software tree view, select to display the GPIB address in the property page.
Validate the connection. In the software tree view, select and click the button.
Review Equipment Setup, Testing the Equipment Connections, and the information about installing Keysight I/O libraries.
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.
Verify that the cable and all connectors are undamaged.
Verify that the LAN cable is securely connected to the PC and the signal generator.
Verify 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 tree view, select to display the Hostname or IP address in the property page.
Validate the connection. In the software tree view, select and click the button.
Run the 'ping' program:
On the computer go to > > > (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 and hostname of the instrument 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.

# For example:

# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
<xxx.xxx.xxx.xxx> localhost
<xxx.xxx.xxx.xxx> <signal generator hostname>
<xxx.xxx.xxx.xxx> <spectrum analyzer hostname>
