Ping Command
The analyzer has the built-in capability of performing a "ping" operation. Ping will request the analyzer to
send a few bytes of information to a specific LAN device. That device will then signal the analyzer that it has
received the information. The analyzer computes the approximate round trip time of the communication
cycle and displays it. For a full test of two-way communications, a ping test should be performed in two
directions.
• First: you should ping from the analyzer to the local area network.
• Second: you should ping from the local area network to the analyzer.
NOTE In the second case, any other network device capable of sending a ping command could be
used, assuming it is connected to the same network. This could be a computer or even
another analyzer.
How to Ping from the Analyzer to the Local Area Network (LAN)
Follow the steps below to verify proper LAN operation (assuming you have a functioning LAN). If no network
LAN is available, see "Testing Between Two Analyzers" on page
1. Make sure the IP address on the analyzer is set properly and that it is unique. If unsure how to check the
IP address, refer to the embedded help in the analyzer.
2. Make sure the subnet mask is 0.0.0.0. If not, note the current setting (to allow setting it back later) and
then set it to 0.0.0.0.
3. Find and note the IP address of another working LAN device on the same network. Make sure this device
is turned on, connected, and is functioning properly.
4. To ping the network device:
a. If the Windows Desktop is not displayed, press UTILITY
Control Panel...
b. On the
Windows Taskbar
Prompt.
c. The command prompt window is displayed.
d. At the prompt, type ping xxx.xxx.xxx.xxx
for the results of a successful ping.
5. The analyzer attempts four cycles of communications with the indicated LAN device.
• It displays the time it took to complete each cycle.
• Each cycle times-out after one second if no communication is established and the message, Request
timed out, is displayed.
• It is common for the first of the four cycles to time-out even though subsequent cycles pass.
• See below for an example output of a successful ping.
C:>ping 141.121.69.162
The letters x represent the IP address of the other device on the network.
