Using Interactive IO
Use the VISA Assistant utility available in the Keysight IO Libraries Suite to verify instrument
communication over the LAN interface. Refer to the section on the "IO Libraries and Programming
Languages" on page 4 for more information.
The Keysight IO Libraries Suite is supported on all platforms except Windows NT. If you are using
Windows NT, refer to the section below on using the VISA Assistant to verify LAN communication.
See the section on "Windows NT and Keysight IO Libraries M (and Earlier)" on page 8 for more information.
NOTE
The following sections are specific to Keysight IO Libraries versions M and earlier and apply
only to the Windows NT platform.
Keysight Signal Generators Programming Guide
A normal response to the ping command will be a total of 9 or 10 packets received with a
minimal average round–trip time. The minimal average will be different from network to
network. LAN traffic will cause the round–trip time to vary widely.
A normal response to the ping command will be a total of 9 or 10 packets received if 10 echo
requests were specified.
If error messages appear, then check the command syntax before continuing with
troubleshooting. If the syntax is correct, resolve the error messages using your network
documentation or by consulting your network administrator.
If an unknown host error message appears, try using the IP address instead of the hostname.
Also, verify that the host name and IP address for the signal generator have been registered
by your IT administrator.
Check that the hostname and IP address are correctly entered in the node names database. To
do this, enter the nslookup <hostname> command from the command prompt.
If there is no response from a ping, no packets were received. Check that the typed address
or hostname matches the IP address or hostname assigned to the signal generator in the
System LAN Setup menu. For more information, refer to
(Keysight MXG)" on page 36

.
Ping each node along the route between your workstation and the signal generator, starting
with your workstation. If a node doesn't respond, contact your IT administrator.
If the signal generator still does not respond to ping, you should suspect a hardware problem.

Check the signal generator LAN connector lights
•
Verify the hostname is not being used with DHCP addressing
If you received 1 to 8 packets back, there maybe a problem with the network. In networks
with switches and bridges, the first few pings may be lost until these devices 'learn' the
location of hosts. Also, because the number of packets received depends on your network
traffic and integrity, the number might be different for your network. Problems of this nature
are best resolved by your IT department.
