establish a LAN connection proceed as follows:
1. Refer to section Assigning an IP Address and learn how to avoid connection errors.
2. Connect an appropriate LAN cable to one of the LAN ports. Use a commercial RJ-45 cable to
establish a non-dedicated network connection, or a cross-over RJ-45 cable to establish a dedicated
connection between the analyzer and a single PC.
Dedicated vs. non-dedicated network connections
There are two methods to establish a LAN connection of the analyzer:
•
A non-dedicated network (Ethernet) connection from the analyzer to an existing network made with
an ordinary RJ-45 network cable. The analyzer is assigned an IP address and can coexist with a
computer and with other hosts on the same network.
•
A dedicated network connection between the analyzer and a single computer made with a cross-over
RJ-45 network cable. The computer must be equipped with a network adapter and is directly
connected to the analyzer. The use of hubs, switches, or gateways is not needed, however, data
transfer is still made using the TCP/IP protocol.
The IP address information is displayed in the Info – Setup Info dialog.
Test Setups with Two LAN Connections
The two LAN connectors on the rear panel of the analyzer are equivalent. With one LAN connector
used to establish a connection to a home/company network, the other one can be used to connect an
additional instrument, e.g. an additional analyzer or signal generator:
Defining the network topology: Router vs. network client
With two LAN connections, it is possible to use the analyzer in two alternative ways:
•
As a client participating in two independent networks, one comprising the home network including
the analyzer, the second consisting of the additional test instrument plus the analyzer.
•
As a data router between the additional test instrument and the home network. This configuration
means that the analyzer and the additional test instrument are integrated into a single network.
The network topology is defined in Windows XP's Control Panel – Network Connections – Local Area
