Accessing the Analyzer's Web Pages

About This Chapter

About This Chapter

Your analyzer has built-in web pages that are accessible with a web browser such as Netscape Navigator or Microsoft® Internet Explorer.

These web pages contain links to general product information, selected on-line documentation, benchmarks, information about your analyzer, and a list of Agilent Technologies offices. You can also e-mail us with your comments and feedback on the Agilent Technologies 87xx family of analyzers.

Before you can access your analyzer with a web browser, you need to connect and configure your analyzer as described in

Chapter 1,

“Connecting and Configuring the Analyzer.”

If your analyzer is directly connected to a PC, without the use of a hub or a larger network, then you probably need to disable the proxy server in the browser. This is because most web browsers are configured to use proxy servers for accessing web pages. If your analyzer is directly connected to your computer, your computer cannot find the proxy server.

If you are communicating to your analyzer over a LAN, then the proxy setting can be left as it is.

Screen Snapshot

Clicking on Get a current screen snapshot shows an exact copy of your analyzer's current screen image. Use your web browser's “reload” or

“refresh” function to get the most current screen image.

The screen image takes a few seconds to load. Do not push any buttons on the analyzer or send any programming commands to it while the snapshot is loading, or an inaccurate image may result.

Before capturing the screen image with your web browser, you may wish to customize the look of the image using the

Color Options

menu on your analyzer. (See your analyzer's User's Guide for more information.)

In particular, you may want to choose

Inverse Video

to create a white background, especially if you plan to print the page from your web browser. See

Figure 2-2

Control the Analyzer with SCPI Commands

Clicking on Control the Analyzer with SCPI Commands launches a Java applet. This applet creates a command-entry dialog box. You can control your analyzer over the LAN by entering SCPI commands in this dialog box. See

Figure 2-3

. Commands or queries are sent to the analyzer by entering the SCPI mnemonic in the SCPI Command: area, and the response from the analyzer is displayed in the Response Messages: area.

Example commands are provided on this web page as well as a link to the SCPI command reference.

It may be helpful to save frequently-sent SCPI command strings in a separate ASCII file. These commands can then be cut and pasted from the ASCII file into the command line of the dialog box, and edited, if necessary, before sending them to the analyzer.

Java is a powerful, cross-platform programming language developed by

Sun Microsystems. See http://www.javasoft.com

for more details.
