General Safety Considerations

Caution

Warning

Before switching on this instrument, make sure that the line voltage selector switch is set to the voltage of the power supply and the correct fuse is installed.

This is a Safety Class I product (provided with a protective earthing ground incorporated in the power cord). The mains plug shall only be inserted in a socket outlet provided with a protective earth contact. Any interruption of the protective conductor, inside or outside the instrument, is likely to make the instrument dangerous. Intentional interruption is

prohibited.

The opening of covers or removal of parts is likely to expose dangerous voltages. Disconnect the instrument from all voltage sources while it is being opened.

The power cord is connected to internal capacitors that may remain live for 10 seconds after disconnecting the plug from its power supply.

These servicing instructions are for use by qualified personnel only. To

avoid electrical shock, do not perform any servicing unless you are

qualified to do so.

What You’ll Learn in This Chapter

This chapter tells you how to connect a computer to your spectrum analyzer via the Hewlett-Packard Interface Bus (HP-IB) or the RS-232 Interface and how to connect a printer

or a plotter. The remainder of the chapter covers procedures to follow if a problem is

encountered.

Connecting Your Spectrum Analyzer to a Computer

The spectrum analyzer works with many popular computers. However, the steps required to connect your spectrum analyzer to a specific computer depend on the computer you are using. Before turning to the interconnection instructions for your computer, please read the following general information.

Configuring Your Computer System

Every computer system has a specific configuration. Your system configuration might include a printer, external disk drive, or plotter. Whenever you add another piece of equipment (for example, your spectrum analyzer), you may need to reconfigure your computer system so that the computer knows where and how to send information to the newly added device.

Some computers do not require configuring when a spectrum analyzer is connected; others

require a simple modification. The most common modification is changing the configuration information stored on the computer’s operating system disk. A few computers require the insertion of an add-on board, or “card.” Refer to your computer documentation if your system needs these modifications.

All of the test programs for HP-IB and RS-232 interfaces are written using of the computer under consideration. If you have never entered or run a BASIC program, refer to your computer documentation.

the

BASIC language

Preparing for Use

l-1

Connecting the Computer to the Spectrum Analyzer

For the HP-IB Interface

Refer to Appendix B for a detailed description of the HP-IB interface.

Appendix B contains instructions for connecting the spectrum analyzer’s HP-IB interface to either an HP 9000 Series 200, or a Series 300 computer, or to an HP Vectra PC equipped with

an HP 82300B BASIC Language Processor. If your computer is not listed, but it supports an HP-IB interface, there is a good possibility that it can be connected to the spectrum analyzer. Consult your computer documentation to determine how to connect external devices on the bus.

For the BS-232 Interface

Refer to Appendix C for a detailed description of the RS-232 interface. Appendix C contains instructions for connecting the spectrum analyzer’s RS-232 interface to

an HP Vectra PC or IBM PC/AT or compatible computers. If your computer is not listed, but it supports a standard RS-232 interface, there is a good possibility that the spectrum analyzer may be connected to the computer. Consult your computer documentation to determine how to connect external devices to your computer’s RS-232 connector.

There are two types of RS-232 devices: data terminal equipment (DTE) and data communication equipment (DCE). Types of DTE devices include display terminals. DCE equipment includes modems and, generally, other computer RS-232 devices. The spectrum analyzer RS-232 port is the DTE-type. Connections from the computer (DCE) to the spectrum analyzer (DTE) are shown in Appendix C.

The

Test

Program

To test the system configuration, a simple test program is provided for each computer listed. After you have connected your computer and spectrum analyzer, you should enter and run the test program on your computer to make sure the computer is sending instructions to the

spectrum analyzer through the interface cable. If the interface is working and the program is entered correctly, a statement is displayed on the computer screen.

Note

Pressing control.

f-1

The listed computer and spectrum analyzer equipment includes the minimum components necessary to establish communication between your spectrum analyzer and computer. If you are using application software, check with your software supplier for specific computer hardware and memory requirements.

Using an interface cable other than the one listed with your computer’s interconnection instructions may prevent proper communication between the spectrum analyzer and computer.

Program

To test the connection between the computer and the spectrum analyzer, turn on your

spectrum analyzer and follow the instructions below.

1. Your HP 9000 Series 200 computer may have either a soft-loaded or built-in language system. If your language system is built-in, remove any disks from the drives and turn on the computer.

2. If your language is soft-loaded, install the BASIC language disk into the proper drive. Turn the computer power on. After a few seconds, the computer is now ready for use.

For further information on loading BASIC on your system, consult your BASIC manual.

Test Program

The program shown below is written to work with computers using

BASICA

(version 2.0 or later) or GW BASIC. To test the interconnection, first load the BASIC language for your computer and specify a communications buffer of 4096 bytes. Use the following command:

BASICA/C:4096

Set the spectrum analyzer baud rate to 9600, to match the baud rate set up for the computer port in the test program. In line 20, the “9600” indicates 9600 baud for the computer port.

Press the following keys to set the baud rate:

Printing or Plotting

You may wish to obtain a permanent record of data displayed on the spectrum analyzer screen.

This can be done using the lcopvl key of the spectrum analyzer, and a printer or plotter.

Note

The HP 7470A plotter does not support 2 plots per page. If you use an HP 7470A plotter with an HP 8590 Series spectrum analyzer, you can select one plot per page or four plots per page, but not 2 plots per page.
