LAN Address Configuration
The E6640A supports both dynamic and static assignment of its IP address, using ports
LAN 1 and LAN 2 respectively.
The LAN 1 port is designed for dynamic IP addressing, using the Dynamic Host
Configuration Protocol. If the your site network supports DHCP, the E6640A will be
assigned an IP address automatically when it is connected to the LAN. Once the address
is assigned, it is listed, along with the computer name, under
System > Show > System.
The address or computer name can be used to find the test set on the LAN. However, to
see the
System > Show > System screen and find this information, it is necessary either
to connect a monitor to the front panel monitor port, or else to use the LAN 2 port to
connect test set to a PC directly.
Using the LAN 1 port to connect the test set directly to the public LAN is potentially
insecure, because the test set does not provide anti-virus protection. Connecting the test
set to the public LAN by way of a PC with antivirus protection is the preferred solution.
The LAN 2 port is designed to use a private static IP address, 192.168.1.2 (changing this
address is possible but not recommended). This port can be used for direct connection to
a PC.
To find the test set on the LAN, you will need to know its IP address or computer name.
If you cannot easily obtain a monitor view of
System > Show > System, you can
determine the computer name using the instrument serial number. The computer name is
in the format A-E6640A-nnnnn, ending in the last five digits of the serial number.
