Preface

About This Manual

This is the user manual for the oscilloscope. It covers the following information:

H Describes the capabilities of the oscilloscope, how to install it and reinstall

its software

H Explains how to operate the oscilloscope: how to control acquisition of,

processing of, and input/output of information

H Lists specifications and accessories of the oscilloscope

This manual is composed of the following chapters:

H Getting Started shows you how to configure and install your oscilloscope

and provides an incoming inspection procedure.

H Operating Basics uses maps to describe the various interfaces for controlling

the oscilloscope, including the front panel and the software user interface.

These maps provide overviews of the product and its functions from several

viewpoints.

H Reference comprises an encyclopedia of topics (see Overview on page 3--1)

that describe the oscilloscope interface and features, and gives background

and basic information on how to use them. (The online help onboard the

oscilloscope application describes the interface, features, and their usage;

detailed descriptions of all programming commands are found in the

TDS7000 Series & CSA7000 Series Programmer Online Guide manual.)

H Appendices provides additional information including the specifications,

measurements, and cleaning information.

Key Features

H TDS7154 Digital Phosphor Oscilloscope

Differences between the oscilloscopes will be called out when necessary; otherwise, the material applies to all oscilloscopes. The word “oscilloscope” refers to all products.

TDS7000 Series oscilloscopes are high performance solutions for verifying, debugging, and characterizing sophisticated electronic designs. The series features exceptional signal acquisition performance, operational simplicity, and open connectivity to the design environment. Classic analog-style controls, a large touch-sensitive display, and graphical menus provide intuitive control. Open access to the Windows operating system enables unprecedented customization and extensibility. Key features include:

H Up to 4 GHz bandwidth and 20 GS/s real time sampling rate, depending on

the model

H Record lengths up to 32,000,000 samples, depending on option

H Fast acquisition at up to 400,000 acquisitions per second for analog

oscilloscope emulation and isolation of data-dependent failures during

Installation

NOTE. The certificate of authenticity (Windows 98 licence agreement) is attached to the rear of your oscilloscope. This certificate proves your ownership of the Windows operating system in your oscilloscope. Without this certificate, you might have to purchase a new Windows license if the hard disk in your oscilloscope ever needs rebuilding or replacement.

H All the standard and optional accessories that you ordered.

Remember to fill out and send in the customer registration card.

Checking the Environment Requirements

Read this section before attempting any installation procedures. This section describes site considerations, power requirements, and ground connections for your oscilloscope.

Site Considerations

Operating Requirements

Connecting Peripherals

The oscilloscope is designed to operate on a bench or on a cart in the normal position (on the bottom feet). For proper cooling, at least three inches (7.62 cm) of clearance is required on both sides of the oscilloscope, and the bottom requires the clearance provided by the oscilloscope feet.

If you operate the oscilloscope while it is resting on the rear feet, make sure that you properly route any cables coming out of the rear of the oscilloscope to avoid damaging them.

CAUTION. Keep the bottom and sides of the oscilloscope clear of obstructions to ensure proper cooling.

The Specifications in Appendix A list the operating requirements for the oscilloscope. Power source, temperature, humidity, and altitude are listed.

The peripheral connections are the same as those you would make on a personal computer. The connection points are shown in Figure 1--1. See Table 1--1 on page 1--8 for additional connection information.

CAUTION. To avoid product damage, power off the oscilloscope or place the oscilloscope in Standby power mode before installing any accessories except a USB mouse or keyboard to the oscilloscope connectors. (You can connect and disconnect USB devices with the power on.) See Powering Off the Oscilloscope on page 1--9.

Windows 98 display settings to achieve the proper resolution for your monitor. To set up a dual display, see page 1--14.

Printer Connect the printer to the EPP (enhanced parallel port)

connector directly. If your printer has a DB-25 connector, use the adapter cable that came with your printer to connect to the EPP connector. For information on printer usage, see Printing Waveforms on page 3--240.

Rackmount Refer to the Rackmount Installation Instructions for information

on installing the rackmount kit.

possible additional accessory installation information not covered in this manual.

Powering On the Oscilloscope

Follow these steps to power on the oscilloscope for the first time.

1. Either one of the following fuse sizes can be used, each size requires a different fuse cap. Both fuses must be the same type. See Table 1--2 and Figure 1--2.

Installation

CAUTION. Connect the keyboard, mouse, and other accessories before applying power to the product.

2. Connect the power cord.

3. If you have an external monitor, connect the monitor to the oscilloscope (see

Setting Up a Dual Display on page 1--14), connect the power cord, and power on the monitor.

4. Turn the Power switch on at the rear panel. (See Figure 1--2 on page 1--8 for switch location.)

5. If the oscilloscope does not power up, push the On/Standby switch to power on the oscilloscope (see Figure 1--3 for the switch location).

On/Standby

Switch

Figure 1- 3: On/Standby switch location

Shutting Down the Oscilloscope

When you push the front-panel On/Standby switch, the oscilloscope starts a shutdown process (including a Windows shutdown) to preserve settings and then removes power from most circuitry in the oscilloscope. Avoid using the rear-panel power switch or disconnecting the line cord to power off the oscilloscope.

NOTE. If you do not use the On/Standby switch to shut down the instrument before powering off the oscilloscope, the oscilloscope will be in the factory Default Setup when powered on the next time.

To completely remove power to the oscilloscope, perform the shutdown just described, set the power switch on the rear panel to off, and then remove the power cord from the instrument.

Installation

Creating an Emergency Startup Disk

Now that you have completed the basic installation process, you should create an emergency startup disk that you can use to restart your oscilloscope in case of a major hardware or software failure. You should create this disk, and then store it in a safe place.

CAUTION. Create this disk and store it in a safe place. It may allow you to recover your Windows 98 installation without rebuilding the entire oscilloscope hard disk.

The emergency startup disk contains basic files to restart your oscilloscope. It also contains files to check and format the hard disk.

Follow these steps to create the emergency startup disk:

1. Minimize the oscilloscope application by selecting Minimize in the File menu.

Backing Up User Files

2. Click the Windows Start button, point to Settings, and click Control Panel.

3. In the Control Panel window, double-click Add/Remove Programs.

4. Click the tab for the Startup Disk page.

5. Insert a floppy disk into the disk drive and follow the on-screen instructions

to create the startup disk.

You should always back up your user files on a regular basis. Use the Back Up tool to back up files stored on the hard disk. The Back Up tool is located in the System Tools folder in the Accessories folder.

1. If the Windows backup program is not installed on your oscilloscope, perform the following steps:

a. Minimize the oscilloscope application by selecting Minimize in the File

b. Click the Windows Start button, Settings, and then Control Panel

c. Double click Add/Remove Programs to display the dialog box

1- 10

d. Click the Windows Setup tab

e. Under Components, double click System Tools

f. Select the Backup check box and then click OK
