Agilent InfiniiVision 4000 X-Series Oscilloscopes User's Guide

21

Web Interface

 

The web interface for InfiniiVision X- Series oscilloscopes also provides 
help for each of its pages.

Microsoft Internet Explorer is the recommended Web browser for 
communication and control of the oscilloscope. Other Web browsers may 
work but are not guaranteed to work with the oscilloscope. The Web 
browser must be Java- enabled with Sun Microsystems

 Java Plug- in.

Before you can use the web interface, you must place the oscilloscope on 
the network and set up its LAN connection.

Accessing the Web Interface

To access the oscilloscope's web interface:

1

Connect the oscilloscope to your LAN (see 

"To establish a LAN 

connection"

on page 331) or establish a point- to- point connection (see 

"Stand- alone (Point- to- Point) Connection to a PC"

on page 332).

It is possible to use a point- to- point connection, but using a normal 
LAN connection is the preferred method.

2

Type the oscilloscope's hostname or IP address in the web browser.

The oscilloscope's web interface Welcome Page is displayed.
