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:
General information about understanding and using the oscilloscope, such as Using the Menu System.
Information about specific menus and controls, such as the Vertical Position Control.
Advice about problems you may face while using an oscilloscope, such as Reducing Noise.
The Help system provides several ways to find the information you need: context-sensitive help, hyperlinks, and an index.
Context-Sensitive Help
The oscilloscope displays information about the last menu displayed on the screen when you push the HELP front-panel button. When viewing help topics, an LED lights next to the multipurpose knob to indicate that the knob is active. If the topic uses more than one page, turn the multipurpose knob to move from page to page within the topic.
Hyperlinks
Most of the help topics contain phrases marked with angle brackets, such as <Autoset>. These are links to other topics. Turn the multipurpose 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.

Installation
Power Cord
Use only the power cord provided with your oscilloscope. Appendix B: Accessories lists the standard and the optional accessories.
Power Source
Use a power source that delivers 90 to 264 VACRMS, 45 to 66 Hz. If you have a 400 Hz power source, it must deliver 90 to 132 VACRMS, 360 to 440 Hz.
Security Loop
Use a standard laptop computer security lock, or thread a security cable through the built-in cable channel to secure your oscilloscope to your location.

Getting Started
Functional Check
Perform this functional check to verify that your oscilloscope is operating correctly.
ON/OFF button
1. Power on the oscilloscope.
Push the DEFAULT SETUP button.
The default Probe option attenuation setting is 10X.
DEFAULT SETUP button
PROBE COMP
2. Set the switch to 10X on the P2220 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 terminals.
3. Push the AUTOSET button. Within a few seconds, you should see a
square wave in the display of about 5V peak-to-peak at 1 kHz.
Push the CH1 MENU button on the front panel twice to remove channel 1, push the CH 2 MENU button to display channel 2, and repeat steps 2 and 3. For 4-channel models, repeat for CH 3 and CH 4.

TDS1000B/2000B Series Oscilloscope User Manual |
Getting Started
Probe Safety
Check and observe probe ratings before using probes.
A guard around the P2220 probe body provides a finger barrier for protection from electric shock.
Finger guard
WARNING. To avoid electric shock when using the probe, keep fingers behind the guard on the probe body.
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.
Voltage Probe Check Wizard
You can use the Probe Check Wizard to verify that a voltage probe is operating properly. The wizard does not support current probes.
The wizard helps you adjust the compensation for voltage probes (usually with a screw on the probe body or probe connector) and set the factor for the Attenuation option for each channel, such as in the CH 1 MENU ► Probe ► Voltage ► Attenuation option.
TDS1000B/2000B Series Oscilloscope User Manual |
5 |
Getting Started
You should use the Probe Check Wizard each time you connect a voltage probe to an input channel.
To use the Probe Check Wizard, push the PROBE CHECK button. If the voltage probe is connected properly, compensated properly, and the Attenuation option in the oscilloscope VERTICAL menu is set to match the probe, the oscilloscope displays a PASSED message at the bottom of the screen. Otherwise, the oscilloscope displays directions on the screen to guide you in correcting these problems.
NOTE. The Probe Check Wizard is useful for 1X, 10X, 20X, 50X, and 100X probes. It is not useful for 500X or 1000X probes, or for probes connected to the EXT TRIG BNC.
NOTE. When the process is complete, the Probe Check Wizard restores the oscilloscope settings (other than the Probe option) to what they were before you pushed the PROBE CHECK button.
To compensate a probe that you plan to use with the EXT TRIG input, follow these steps:
1.Connect the probe to any input channel BNC, such as to CH 1.
2.Push the PROBE CHECK button and follow the directions on the screen.
3.After you verify that the probe functions and is compensated properly, connect the probe to the EXT TRIG BNC.

1.Push the CH 1 MENU ► Probe ► Voltage ► Attenuation option and select 10X. Set the switch to 10X on the P2220 probe and connect the probe to channel 1 on the oscilloscope. If you use the probe hook-tip, ensure a proper connection by firmly inserting the tip onto the probe.
2.Attach the probe tip to the PROBE COMP ~5V@1kHz terminal and the reference lead to the PROBE COMP chassis terminal. Display the channel, and then push the AUTOSET button.
3.Check the shape of the displayed waveform.

4.If necessary, adjust your probe. The P2220 probe is shown.
Repeat as necessary.

Getting Started
Probe Attenuation Setting
Probes are available with various attenuation factors which affect the vertical scale of the signal. The Probe Check Wizard verifies that the attenuation factor in the oscilloscope matches the probe.
As an alternative method to Probe Check, you can manually select the factor that matches the attenuation of your probe. For example, to match a probe set to 10X connected to CH 1, push the CH 1 MENU ► Probe
► Voltage ► Attenuation option, and select 10X.
NOTE. The default setting for the Attenuation option is 10X.
If you change the Attenuation switch on the P2220 probe, you also need to change the oscilloscope Attenuation option to match. Switch settings are 1X and 10X.
Attenuation switch
NOTE. When the Attenuation switch is set to 1X, the P2220 probe limits the bandwidth of the oscilloscope to 6 MHz. To use the full bandwidth of the oscilloscope, be sure to set the switch to 10X.
Current Probe Scaling
Current probes provide a voltage signal proportional to the current. You need to set the oscilloscope to match the scale of your current probe. The default scale is 10 A/V.
For example, to set the scale for a current probe connected to CH 1, push the CH 1 MENU ► Probe ► Current ► Scale option, and select an appropriate value.
8 |
TDS1000B/2000B Series Oscilloscope User Manual |
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 you should always run the routine if the ambient temperature changes by 5 °C (9 °F) or more. The routine takes about two minutes.
For accurate calibration, power on the oscilloscope and wait twenty minutes to ensure it is warmed up.
To compensate the signal path, disconnect any probes or cables from the input connectors. Then, access the UTILITY ► Do Self Cal option, and follow the directions on the screen.
