Logic Analyzers

Introducing the LAN Interface

The HP Logic Analyzer

LAN

interface lets you connect your logic analyzer

an Ethernet network that uses TCP/IP. With

the

LAN

Interface, you can:

• Set up

and

run

measurements using

the

logic analyzer's XWindow

interface.

• Copy measurement data from

the

logic analyzer to your computer using

File Transfer Protocol program (ftp) or Network File System (NFS).

• Save

and

restore configurations.

• Program

the

logic analyzer.

Requirements

order to use your

logic analyzer on

the

LAN,

you need the following

equipment and software:

•

1660C/CS-series logic analyzer with

LAN

option or

1670A-series

logic analyzer.

• Ethernet local

area

network using TCP/lP protocol.

•

you are using a

PC,

NFS

program or ftp program.

•

you want to use

the

logic analyzer's XWindow interface, X server

program running on your computer.

Characteristics

Physical

Connection

RJ-45 connector for direct connection to lOBase-T ("ethertwist")

networks

BNC

connector for direct connection to 10Base2 ("thinlan") networks

Supported

Protocols

Transmission Control Protocol/lnternet Protocol (TCP/lP)

Network File System (NFS)

File Transfer Protocol (ftp)

XWindow System Version 11, release 5 (X11R5)

Simple Network Management Protocol (SNMP)

This Book

This book shows you how to

coIIDect,

use,

and

troubleshoot your HP logic

analyzervia a Local Area Network (LAN)

connection. This book contains the

following chapters:

• Chapter 1 provides information about

connecting the logic analyzer to

the

network. To effectively use this

chapter, you should be familiar with

your network setup

and

operation.

• Chapter 2 shows you howto access

the

logic analyzer's file system. This is

a prerequisite for some ofthe other

things you can

with a logic analyzer

the

network.

• Chapter 3 shows you how to display

the

analyzer interface on an XWindow

server,

and

describes

the

basics of

using

the

interface.

• Chapter 4 shows you how to retrieve

measurement data, screen images,

and

status information from your logic

analyzer

the

LAN,

and

how to copy

and

restore

configurations.

• Chapter 5 shows you methods for

programming the logic analyzer via

the

network connection.

• Chapter 6 contains additional

infonnation on the logic analyzer's

directory structure

and

dynamic files.

• Chapter 7 describes what to

you

have a problem using

the

logic

analyzer

your network.
