Introducing the LAN Interface
The Logic Analyzer LAN interface lets you connect your logic analyzer to an
Ethernet network that uses TCP/IP. With the LAN Interface, you can:
•Set up an run measurements using the logic analyzer’s X Win ow
interface.
•Copy measurement ata from the logic analyzer to your computer using
File Transfer Protocol program (ftp) or Network File System (NFS).
•Save an restore configurations.
•Program the logic analyzer.
Requirements
In or er to use your Agilent Technologies logic analyzer on the LAN, you
nee the following equipment an software:
•Agilent Technologies 1660C/CS-series logic analyzer with LAN option or
Agilent Technologies 1670A-series logic analyzer.
•Ethernet local area network using TCP/IP protocol.
•If you are using a PC, NFS program or ftp program.
•If you want to use the logic analyzer’s X Win ow interface, X server
program running on your computer.

In This Book
This book shows you how to connect,
use, an troubleshoot your Agilent
Technologies logic analyzer via a Local
Area Network (LAN) connection. This
book contains the following chapters:
•Chapter 1 provi es information about
connecting the logic analyzer to the
network. To effectively use this
chapter, you shoul be familiar with
your network setup an operation.
•Chapter 2 shows you how to access
the logic analyzer’s file system. This is
a prerequisite for some of the other
things you can o with a logic analyzer
on the network.
•Chapter 3 shows you how to isplay
the analyzer interface on an X Win ow
server, an escribes the basics of
using the interface.
•Chapter 4 shows you how to retrieve
measurement ata, screen images, an
status information from your logic
analyzer on the LAN, an how to copy
an restore configurations.
•Chapter 5 shows you metho s for
programming the logic analyzer via the
network connection.
•Chapter 6 contains a itional
information on the logic analyzer’s
irectory structure an ynamic files.
•Chapter 7 escribes what to o if you
have a problem using the logic
analyzer on your network.

To connect to your network
1Turn off the logic analy er.
2Connect the analy er to your network using an RJ-45 or BNC
connector.
Ethertwist an thinlan are the two most common types of LAN network
connection. Ethertwist uses unshiel e twiste pair an an RJ-45 connector,
an resembles a stan ar mo ular phone line. Thinlan uses coaxial cable. If
you are unsure what your network uses for its physical connection, contact
your local network a ministrator.
The logic analyzer LAN ports are on the back panel. The RJ-45 connector
goes in the port labele "LAN-TP" an the BNC attaches to the port labele
"LAN-BNC".
3Turn on the logic analy er.
