Help System

The oscilloscope has a Help system with topics that cover all the features of the oscilloscope. You can use the Help system to display several kinds of information:

H General information about understanding and using the

oscilloscope, such as Using the Menu System.

H Information about specific menus and controls, such as the

Vertical Position Control.

H Advice about problems you may face while using an oscillo-

scope, such as Reducing Noise.

The Help system provides three ways for you to find the information you need: context-sensitive, hyperlinks, and an index.

Preface

Context-Sensitive

The oscilloscope displays information about the last menu displayed on the screen when you push the HELP front-panel button. The HELP SCROLL LED lights under the HORIZONTAL POSITION knob to indicate the alternative function of the knob. If the topic uses more than one page, turn the HELP SCROLL knob to move from page to page within the topic.

TDS1000/2000-Series Digital Oscilloscope User Manual

Preface

Hyperlinks

Most of the help topics contain phrases marked with angle bracke ts, such as < Autoset>. These are links to ot her topi cs. Turn the HELP SCROLL knob to move the highlight from one link to another. Push the Show Topic option button to display the topic corresponding to the highlighted link. Push the Back option button to return to the previous topic.

Index

Push the front--panel HELP button, then push the Index option button. Push the Page Up or Page Down option buttons until you find the index page that contains the topic you want to view. Turn the HELP SCROLL knob to hi ghlight a help topic. Push the Show Topic option button to display the topic.

NOTE. Push the Exit option button or any menu button to remove the Help text from the screen and return to displaying waveforms.

TDS1000/2000-Series Digital Oscilloscope User Manual

Conventions

This manual uses the following conventions:

H Front-panel buttons, knobs and connectors appear in all

uppercase letters. For example: HELP, PRINT.

H Menu options appear with the first letter of each word in upper

case. For example: Peak Detect, Window Zone.

Preface

Front-panel buttons and

knob labels — All upper case

Option buttons — First letter of

1. Power on the oscilloscope.

Wait until the display shows that all power-on tests passed. Push the DEFAULT SETUP button. The default Probe option attenuation setting is 10X.

2. Set the switch to 10X on the P2200 probe

and connect the probe to channel 1 on the oscilloscope. To do this, align the slot in the probe connector with the key on the CH 1 BNC, push to connect, and twist to the right to lock the probe in place.

Connect the probe tip and reference lead to the PROBE COMP connectors.

3. Push the AUTOSET button. Within a few

seconds, you should see a square wave i n the display of about 5 V peak-to-peak at 1kHz.

Push the CH 1 MENU button twice to remove channel 1, push the CH 2 MENU button to display channel 2, repeat steps 2 and 3. For 4-channel models, repeat for CH 3 and CH 4.

Probe Safety

A guard around the probe body provides a finger barrier for protection from electric shock.

WARNING. To avoid electric shock when using the probe, keep fingers behind the guard on the probe body.

Finger guard

To avoid electric shock while using the probe, do not touch metallic portions of the probe head while it is connected to a voltage source.

Connect the probe to the oscilloscope and connect the ground terminal to ground before you take any measurements.

TDS1000/2000-Series Digital Oscilloscope User Manual

Probe Check Wizard

You can use the Probe Check Wizard to quickly verify that your probe is operating properly. The wizard also helps you adjust the probe compensation (usually adjusted with a screw on the probe body or probe connector) and set the Probe option a ttenuation factor in the vertical menu (for example, the menu that appears when you push the CH 1 MENU button).

You should do this each time you connect a probe to an input channel.

To use the Probe Check Wizard, push the PROBE CHECK button. If your probe is connected properly, compensated properly, and the Probe entry in the oscilloscope VERTICAL menu is set to match your probe, the oscilloscope will display a PASSED message at the bottom of the screen. Otherwise, the oscilloscope will display directions on the screen to guide you in correcting these problems.

Getting Started

NOTE. Probe check is useful for 1X, 10X, and 100X probes; it does not work with the EXT TRIG front-panel BNC.

To compensate a probe connected to the EXT TRIG front-panel BNC, follow these steps:

1. Connect the probe to any channel BNC, such as to CH 1.

2. Push the PROBE CHECK button and follow the directi ons on the

screen.

3. After you verify that the probe functions properly and is

compensated, connect the probe to the EXT TRIG BNC.

TDS1000/2000-Series Digital Oscilloscope User Manual

Probe Attenuation Setting

Probes are available with various attenuation factors which affect the vertical scale of the signal. The Probe Check function verifies that the Probe attenuation option matches the attenuation of the probe.

As an al ternative method to Probe Check, you can push a vertical menu button (such as the CH 1 MENU button), and select the Probe option that matches the attenuation factor of your probe.

NOTE. The default setting for the Probe option is 10X.

Be sure that the Attenuation switch on the P2200 probe matches the Probe option in the oscilloscope. Switch settings are 1X and 10X.

Getting Started

Attenuation switch

NOTE. When the Attenuation switch is set to 1X, the P2200 probe limits the bandwidth of the oscilloscope to 7 MHz. To use the full bandwidth of the oscilloscope, be sure to set the switch to 10X.

Getting Started

Self Calibration

The self calibration routine lets you optimize the oscilloscope signal path for maximum measurement accuracy. You can run the routine at any time but should always run the routine if the ambient tempe rature changes by 5_ Cormore.

To compensate the signal path, disconne ct a ny probes or cable s from the front-panel input connectors. Then, push the UTILITY button, select the Do Self Cal option and follow the directions on the screen.

Understanding Oscilloscope Functions

Setting Up the Oscilloscope

You should become familiar with three functions that you may use often when operating your oscilloscope: Autoset, saving a setup, and recalling a setup.

Using Autoset

The Autoset function obtains a stable waveform display for you. It automatically adjusts the vertical scale, horizontal scale and trigger settings. Autoset also displays several automatic measurements in the graticule area, depending on the signal type.

Saving a Setup

The oscilloscope saves the current setup if you wait five seconds after the last change before you power off the oscilloscope. The oscilloscope recalls this setup the next time you apply power.

You can use the SAVE/RECALL Menu to permanently save up to ten different setups.

Recalling a Setup

The oscilloscope can recall the last setup before power off, any of your saved setups or the default setup. See page 175.
