Page 15: Introduction To Oscilloscopes And Probes
Introduction to Oscilloscopes and Probes The environment around us contains various energy sources, such as electronic appliances, which generate signals. Oscilloscopes allow you to observe these signals to analyze the performance of their energy sources. This module introduces you to oscilloscopes and the methods to measure electrical signals by using oscilloscopes and associated probes.
Page 16: Getting To Know Oscilloscopes
Introduction to Oscilloscopes and Probes Getting to Know Oscilloscopes This section introduces you to oscilloscopes and describes the different types of oscilloscopes and their functions. The section includes the following topics: • Introduction to Oscilloscopes • Types of Oscilloscopes • Oscilloscope Terminology Introduction to Oscilloscopes You use an oscilloscope to display electrical signals as...
Page 17 Introduction to Oscilloscopes and Probes You can use an oscilloscope to determine the following: • The frequency of an oscillating signal • The malfunctioning component in an electrical circuit • Whether the signal is direct current (DC) or alternating current (AC) •...
Page 18 Introduction to Oscilloscopes and Probes An oscilloscope contains various controls that help you analyze waveforms displayed on a graphical grid called a graticule. The vertical or Y-axis of the graticule typically represents voltage while the horizontal or X-axis typically represents time. Figure 1.1 shows how an oscilloscope displays voltage and time.
Page 19: Types Of Oscilloscopes
Introduction to Oscilloscopes and Probes Types of Oscilloscopes Electronic equipment can be categorized into two types, analog and digital. Analog equipment use variable voltages while digital equipment use binary numbers that represent voltage samples. Similarly, oscilloscopes are categorized into analog and digital. Figure 1.2 shows an analog and a digital oscilloscope.
Page 20 Introduction to Oscilloscopes and Probes Analog Oscilloscopes Let us look at how analog oscilloscopes work. Figure 1.3 shows a block diagram of an analog oscilloscope. Figure 1.3: Block diagram of an analog oscilloscope When you connect an analog oscilloscope to a circuit, the voltage signal from the circuit travels to the vertical deflection plates of the oscilloscope screen, which is a phosphor-coated cathode-ray tube (CRT).
Page 21 Introduction to Oscilloscopes and Probes A positive voltage causes the dot to move up while a negative voltage causes the dot to move down. The signal also travels to a trigger system, which initiates a horizontal sweep. The trigger causes the time base on the X-axis of the display grid to move the glowing dot from left to right across the screen within a specified time interval.
Page 22 Introduction to Oscilloscopes and Probes In analog oscilloscopes, the CRT limits the range of sine wave frequencies that the oscilloscope can display. At low frequencies, the signal appears as a bright, slow-moving dot that does not display the waveform. When signal frequencies exceed the display speed of the CRT, the displayed signal is distorted, attenuated, or both.
Page 23 Introduction to Oscilloscopes and Probes Digital Oscilloscopes In contrast to analog oscilloscopes, digital oscilloscopes use an analog-to-digital converter (ADC). An ADC converts the voltage being measured into a digital format. A digital oscilloscope acquires a waveform as a series of signal samples, which are stored in its memory and then reassembled for viewing on the screen.
Page 24 Introduction to Oscilloscopes and Probes Digital Storage Oscilloscopes In a DSO, an ADC takes samples of a signal at discrete points in time and converts the voltage at these points to digital values called sample points. The DSO contains a sample clock that determines the frequency at which the ADC takes samples.
Page 25 Introduction to Oscilloscopes and Probes Figure 1.5 shows the block diagram of a DSO. Figure 1.5: Block diagram of a DSO A DSO contains a microprocessor (represented by uP in the figure above) that processes the signal, manages display activities, and interprets front panel controls. TDS1000B and TDS2000B Series Oscilloscopes –...
Page 26 Introduction to Oscilloscopes and Probes Digital Phosphor Oscilloscopes A DPO uses electronic Digital Phosphor to display waveforms on the screen. Digital Phosphor is a database that uses separate cells to store information corresponding to each pixel of the oscilloscope display screen. Every time a waveform triggers, the cells that map to the display path of the waveform are updated with intensity information.
Page 27 Introduction to Oscilloscopes and Probes Figure 1.6 shows how a DPO works. Figure 1.6: Block diagram of DPO Similar to a DSO, a DPO also uses a microprocessor for display management, measurement automation, and analysis of the displayed waveforms.

Page 28: Oscilloscope Terminology
Introduction to Oscilloscopes and Probes Oscilloscope Terminology This topic discusses the terminology related to the following categories: • Types of waves • Waveform measurements • Performance terms Types of Waves You use waveform shapes to analyze a signal. Different types of waveforms represent different types of signals. Waveforms are classified into the following groups: •...
Page 29 Introduction to Oscilloscopes and Probes Sine Waves A sine wave is a basic waveform that represents voltage change with time. Signals produced by the oscillator circuit in a signal generator are sine waves. Most AC power sources produce sine waves. Figure 1.7 shows a sine wave. Figure 1.7: Sine wave TDS1000B and TDS2000B Series Oscilloscopes –...
Page 30 Introduction to Oscilloscopes and Probes Square and Rectangular Waves A square wave represents voltage signals that turn on and off at regular intervals. It is a standard wave used for testing amplifiers, televisions, radios, and computer circuits. A rectangular wave represents high and low time periods of a square wave that are unequal.
Page 31 Introduction to Oscilloscopes and Probes Step and Pulse Waves Step and pulse waves are generated only once from a circuit. These signals are also called single-shot or transient signals. A step wave indicates a sudden change in voltage, which may be the result of turning on an electric switch. A pulse wave represents a sudden change in signal level followed by a return to the original level.
Page 32 Introduction to Oscilloscopes and Probes Sawtooth and Triangle Waves Sawtooth and triangle waves represent a linearly changing voltage required to control a device. A sawtooth wave has a rising rate of change, which differs from its falling rate of change. A triangle wave has a rising rate of change equal to its falling rate of change.
Page 33 Introduction to Oscilloscopes and Probes Complex Waves Some waveforms, formed by a combination of the characteristics of sines, squares, steps, and pulses, are called complex waves. Complex waves can represent signal information embedded in the form of amplitude, phase, and/or frequency variations. Figure 1.11 shows a complex wave.
Page 34 Introduction to Oscilloscopes and Probes Waveform Measurements You use waveform measurements to determine specific characteristics of waveforms. Frequency and Period Frequency represents the number of times a signal repeats itself in one second. The frequency of a signal is measured in Hertz (Hz).
Page 35 Introduction to Oscilloscopes and Probes Phase and Phase Shift A sine wave moves through 360° in one cycle. You can use this phase information to calculate the time elapsed since the reference or beginning point of the sine wave. Figure 1.13 shows phase along a sine wave.
Page 36 Introduction to Oscilloscopes and Probes Performance Terms Some terms and concepts related to how oscilloscopes work are discussed below. Bandwidth Bandwidth is the sine wave frequency range of an oscilloscope. By convention, bandwidth specifies the frequency at which the amplitude of the displayed sine wave reduces to 70.7% of the amplitude of the applied sine wave signal.
Page 37: Getting To Know Probes
Introduction to Oscilloscopes and Probes Getting to Know Probes This section describes the different types of probes and their applications. It includes the following topics: • Introduction to Probes • Types of Voltage Probes • How Probes Affect Measurements Introduction to Probes A probe is an input device for an oscilloscope.
Page 38: Types Of Voltage Probes
Introduction to Oscilloscopes and Probes Types of Voltage Probes There are two types of voltage probes, passive and active. Most probes are packaged with standard accessories. These accessories usually include a ground lead clip that you can attach to a ground signal source, a compensation adjustment tool, and one or more probe tip accessories to help connect the probe to test points.
Page 39 Introduction to Oscilloscopes and Probes Passive Voltage Probes Passive voltage probes consist of wires, connectors, resistors, and capacitors. Passive voltage probes typically have attenuation factors of 1X, 10X, and 100X for different voltage ranges. Attenuation factor represents the number of times a probe attenuates a signal.
Page 40 Introduction to Oscilloscopes and Probes Active Voltage Probes Active voltage probes contain active components such as transistors. Often, the active device is a field-effect transistor (FET). An active FET voltage probe can provide a very low input capacitance. As a result, active FET probes have predefined bandwidths ranging from 500 MHz to more than 4 GHz.
Page 41: How Probes Affect Measurements
Introduction to Oscilloscopes and Probes How Probes Affect Measurements To display a signal on an oscilloscope, the signal is diverted to the oscilloscope input circuit. Depending on the relative impedance values, the addition of a probe to a test point can cause loading of the signal source.
Page 42 Introduction to Oscilloscopes and Probes To minimize this loading effect, you can try the following remedies: • Use a higher impedance probe. • Measure the signal at a test point where the impedance is lower. For example, cathodes, emitters, and sources, have lower impedances than plates, collectors, and drains.
Page 43 Introduction to Oscilloscopes and Probes Capacitive Loading An increase in signal frequency or transition speed decreases the reactive impedance of a capacitive element. Consequently, capacitive loading increases the rise and fall times on fast transition waveforms and decreases the amplitude of high frequency details in waveforms. When the output of a pulse generator is tested, the probe input capacitance and resistance will interact with the pulse generator impedance.
Page 44 Introduction to Oscilloscopes and Probes Bandwidth Consideration Bandwidth measurement system issues include the bandwidth of both the probe and the oscilloscope. Bandwidth is a sine wave specification. Bandwidth specifies the maximum frequency of a sine wave that can appear on the oscilloscope display with a maximum of 29.3% decrease in amplitude.

Page 66: Probe Compensation
Getting Started with the TDS1000B and TDS2000B Series Oscilloscopes Probe Compensation When you attach a passive voltage attenuation probe to an oscilloscope, the capacitances of both the probe cable and the oscilloscope’s input combine. This combined capacitance must match the capacitance of the input attenuation circuit of the probe.
Page 67 Getting Started with the TDS1000B and TDS2000B Series Oscilloscopes The following procedure enables you to balance the capacitive and resistive effects of a probe and an oscilloscope by compensating the probe. This procedure assumes that the oscilloscope retains the settings from the previous preliminary functional check procedure (page 2-13).

VERTICAL control knobs The VERTICAL controls for each channel consist of two knobs, the VOLTS/DIV knob and the POSITION knob. VOLTS/DIV knob You use the VOLTS/DIV knob to set and change the vertical voltage scale for the displayed waveform.
Page 163 Using VERTICAL Controls Figure 3.1 shows the VERTICAL control sections of a 2-channel and a 4-channel oscilloscope respectively. Figure 3.1: TDS1012B and TDS2024B VERTICAL control section TDS1000B and TDS2000B Series Oscilloscopes – Operator Training Kit...
Page 164: Setting Up Vertical Controls
Using VERTICAL Controls Setting Up VERTICAL Controls Before you use the VERTICAL controls, you must ensure that the oscilloscope is set up for the VERTICAL controls. To set up a TDS1000B/TDS2000B oscilloscope for the VERTICAL controls, follow these steps: 1. Connect two P2220 probes to the CH1 and CH2 BNC input connectors on the front panel.
Page 165 Using VERTICAL Controls In the VERTICAL section, turn the VOLTS/DIV and POSITION knobs for CH1 2.00V in the top half of the display, and CH2 2.00V in the bottom half of the display. 5. In the TRIGGER section, use the LEVEL knob to set the trigger level readout at the bottom right of the display for CH1 (+slope symbol) 1.60V.
Page 166: Switching The Input Coupling
Using VERTICAL Controls After you set up your oscilloscope for VERTICAL controls, you can perform various procedures, such as switching the input coupling of a signal, modifying the vertical scale, and changing the vertical position of a waveform. Switching the Input Coupling Coupling is the method you use to connect an electrical signal from one device to another.
Page 167 Using VERTICAL Controls You can change the type of input coupling to view the various components of a signal. For example, you can use vertical AC coupling to view an AC signal, such as ripple, which is riding on a large DC offset. AC coupling allows you to view such signals without any special offset controls.
Page 168 Using VERTICAL Controls 3. Push the appropriate side-screen menu button to select Coupling AC. The waveform shifts down because AC coupling blocks the DC component of the signal. However, the ground reference arrow and the trigger level reference arrow at the left and right of the display, respectively, do not shift from their initial positions.
Page 169 Using VERTICAL Controls 6. Push the appropriate side-screen menu button to select Coupling DC. 7. Turn the CH1 POSITION knob counterclockwise to set the vertical position at 0.00 divs (0.00V). Notice that the flatness of the probe compensation waveform changes when you switch from AC coupling to DC coupling.
Page 170 Using VERTICAL Controls You can see the positive peaks of the waveform with 100 divisions of position offset, as shown in Figure 3.3. This allows you to analyze signal details that would otherwise not be visible. Figure 3.3: Vertical display, with 100 divisions of offset This procedure is applicable to scenarios where you need to observe the change in amplitude of a square wave inverter or a DC power supply when load is applied.
Page 171 Using VERTICAL Controls This high DC offset capability of the oscilloscope also allows logic pulses that are referenced away from ground to be positioned on screen for accurate measurements. This allows you to view logic signals, such as ECL, that have their high and low levels biased several volts from ground.
Page 172: Vertical Control Menu Buttons
Using VERTICAL Controls VERTICAL Control MENU Buttons You use the various side-screen menu buttons of VERTICAL controls to select special functions, such as the input coupling for the signal, the bandwidth limit of the oscilloscope, and the probe attenuation factor.

Page 202: Trigger Controls
Using TRIGGER Controls Trigger Controls Triggering a signal at the correct point is essential to ensure the proper display of a waveform. You can use the TRIGGER controls on the front panel to stabilize repeating signals as well as to capture single-shot waveforms. Figure 5.1 shows the TRIGGER control sections on the front panel.
Page 203 Using TRIGGER Controls The TRIGGER controls on the front panel consist of the following: LEVEL knob You use this knob to set the triggering level while using the edge trigger. TRIG MENU button You use this button to display the trigger menu. The trigger menu contains various options such as trigger type, trigger source, and trigger mode.
Page 204: Trigger Menu Controls
Using TRIGGER Controls TRIG VIEW button You use this button to display the trigger waveform instead of the channel waveforms. You use this button to check how trigger settings, such as trigger coupling, affect the triggering signal. You need to keep this button pressed to view the trigger waveform.
Page 205 Using TRIGGER Controls You use Video triggering to trigger on the fields or lines of an NTSC, a PAL, or a SECAM standard video signal. When you choose video triggering on a TDS1000B/TDS2000B oscilloscope, the trigger is automatically referenced to the negative part of the video signal.
Page 206 Using TRIGGER Controls 4. On the top of the front panel, push the AUTOSET button. 5. In the HORIZONTAL section, turn the SEC/DIV knob to set the time base setting on the display for M 2.50us. 6. In the TRIGGER section, push the TRIG MENU button. This step is for you to see that Edge is selected by default.
Page 207 Using TRIGGER Controls You will see a display showing the Edge triggering setup similar to that shown in Figure 5.2. Figure 5.2: Edge triggering TDS1000B and TDS2000B Series Oscilloscopes – Operator Training Kit...
Page 208: Selecting The Signal Coupling For A Trigger
Using TRIGGER Controls Selecting the Signal Coupling for a Trigger You can select the coupling type for a trigger when you choose Edge triggering. You can choose to select DC, Noise Reject, HF Reject, LF Reject, or AC coupling for a trigger.
Page 209 Using TRIGGER Controls This procedure assumes that the oscilloscope retains the settings from the previous procedure. To select a coupling type for a trigger, follow these steps: 1. In the TRIGGER section, push the TRIG MENU button. 2. Push the appropriate side-screen menu button to select Coupling HF Reject.
Page 210 Using TRIGGER Controls You will see a waveform similar to that shown in Figure 5.3. This trigger signal has a slower rise time and is the result of the low pass HF reject filter. This trigger selection rejects the high-speed components in the triggering signal. Figure 5.3: Triggering waveform with HF Reject coupling 5-10 TDS1000B and TDS2000B Series Oscilloscopes –...
Page 211 Using TRIGGER Controls HF Reject only allows signal components below 50 kHz to pass to the trigger circuit. This helps to reduce the effects of high frequency noise that might cause triggering problems. Noise Reject allows all components of a signal to pass to the trigger circuit, but increases the peak-to-peak signal required to trigger the signal.
Page 212: Using An External Trigger
Using TRIGGER Controls Using an External Trigger You can select various sources, such as an input channel or the power source of the oscilloscope, to trigger a displayed signal. Consider an example where you have a circuit that uses a clock signal as a reference.
Page 213 Using TRIGGER Controls The following procedure enables you to use an external trigger source or an unused channel, other than the displayed acquisition input channels, to trigger a displayed signal. You can use the external trigger input (or an unused channel) to trigger on certain unique aspects of this trigger signal, such as pulse width and edge level.
Page 214 Using TRIGGER Controls 4. On the top of the front panel, push the AUTOSET button. 5. Connect a (10X passive) probe to the EXT TRIG input connector. 6. Connect the external trigger probe tip to the CLK 20MHz signal on pin 2 and the external trigger probe ground lead to GND on pin 1 of the Training 1 signal board.
Page 215 Using TRIGGER Controls Figure 5.4: Eye Diagram display of pseudo random signal triggered by external clock signal TDS1000B and TDS2000B Series Oscilloscopes – Operator Training Kit 5-15...
Page 216 Using TRIGGER Controls This eye diagram display shows that the positive and negative transition edges of the signal are all synchronized with the clock, as is expected. When the edges are not stable relative to the clock, then jitter is occurring. This is a very important issue for communications signals.
Page 217: Triggering On A Specific Pulse Width
Using TRIGGER Controls Triggering on a Specific Pulse Width A TDS1000B/TDS2000B oscilloscope can be set to trigger on a pulse based on its width. This feature can be used to isolate and analyze a unique pulse in a complex data stream.
Page 218 Using TRIGGER Controls You will see a waveform similar to that shown in Figure 5.5. Figure 5.5: Pseudo random communications signal without holdoff 4. In the TRIGGER section, push the TRIG MENU button. 5. Push the appropriate side-screen menu button to select Type Pulse.
Page 219 Using TRIGGER Controls 6. Push the appropriate side-screen menu button to select Source CH1. This option may already be selected by default. 7. Push the appropriate side-screen menu button to select When =. This option may already be selected by default. 8.
Page 220 Using TRIGGER Controls You should see a display similar to the following Figure 5.6. Figure 5.6: Unique Pulses with pulse widths of approximately 297 ns This special pulse triggering condition shows the unique pulse in this signal that is very close to 300 ns in width. Pulse triggering allows you to trigger on and isolate pulses that are less than, equal to, greater than, or not equal to the pulse width value that you select.
Page 221 Using TRIGGER Controls This procedure is useful in scenarios where you need to trouble shoot disc drives and remote controls. A typical command signal of remote control has a 0.5 ms presignal pulse followed by a delay of 3 ms and then followed by a 7 ms six-bit biphase code word.
Page 222: Capturing A Single-Shot Signal
Using TRIGGER Controls Capturing a Single-shot Signal Noise from the signal, probes, and ground leads can cause signal distortions. For example, probe tips and ground leads have inductance. This inductance can interact with the probe and circuit capacitance to cause a damped sinusoidal variation on pulses with fast edge transitions.
Page 223 Using TRIGGER Controls To perform the step response procedure, follow these steps: 1. Connect the CH1 probe tip to the FAST RISE TIME signal on pin 16 and the CH1 ground lead to GND on pin 1 of the Training 1 signal board. 2.
Page 224 Using TRIGGER Controls 7. In the TRIGGER section, turn the LEVEL knob to set the trigger level to 200mV. 8. On the front panel, push the SINGLE SEQ button. The word Ready will appear at the top of the display. 9.
Page 225 Using TRIGGER Controls You will see a waveform similar to that shown in Figure 5.7. Figure 5.7: Step response waveform with a ground lead Overshoot and ringing are caused by the inductance of the probe ground and signal tip leads that interact with the probe and circuit capacitance.
Page 226 Using TRIGGER Controls To view the step response signal without overshoot and ringing, follow these steps: 1. Pull the probe tip out of the probe tip lead. 2. Insert exposed probe tip into the probe socket on the Training 1 signal board. 3.
Page 227 Using TRIGGER Controls You will see a waveform similar to that shown in Figure 5.8. Figure 5.8: Step response waveform without a ground lead Note that no ringing occurs in the step response when the probe ground and signal tip leads are kept short. This procedure points out the importance of keeping probe leads short when analyzing signals with fast rise and/or fall times.
Page 228: Trigger Holdoff Controls
Using TRIGGER Controls Trigger Holdoff Controls A complex repeating signal is difficult to trigger on and see as a stable waveform display. You can use advanced pulse triggering to capture the signal details of interest, or you can trigger on a different signal, if it is available. You can also use trigger holdoff to stabilize a complex repeating waveform.
Page 229: Assigning Trigger Holdoff To A Pseudo Random Signal
Using TRIGGER Controls Assigning Trigger Holdoff to a Pseudo Random Signal The following procedure enables you to assign a holdoff time for the trigger generated by the PSEUDO RANDOM signal from pin 5 of the Training 1 signal board. This enables you to see a stable waveform display.
Page 230 Using TRIGGER Controls Figure 5.10: Stable display of pseudo random communications signal by using trigger holdoff Observe that assigning a trigger holdoff time can stabilize the display of a repeating signal. You can also modify the horizontal scale of a displayed waveform by adjusting the SEC/DIV setting.
Page 231: Assigning Trigger Holdoff To An Am Signal
Using TRIGGER Controls You can assign a trigger holdoff to either Edge or Video triggering. In addition, you can assign a trigger holdoff when the oscilloscope is in the Normal or Auto trigger mode. It may be difficult to see a stable display for a repeating digital signal, such as a pseudo random signal, on an oscilloscope because edge transitions occur at many places within the waveform.
Page 232 Using TRIGGER Controls Figure 5.11 shows the updating overlay of the amplitude modulation region of an amplitude modulated (AM) signal. Figure 5.11: Complex AM signal without holdoff To observe a stable display of the amplitude modulation of a complex repeating signal, you must adjust the trigger level within the amplitude modulation region of the displayed waveform.
Page 233 Using TRIGGER Controls The next procedure enables you to analyze the amplitude modulation region of a complex repeating signal by assigning a trigger holdoff in the amplitude modulation region of the signal. To assign a trigger holdoff for an AM signal, follow these steps: 1.

Page 242: Acquire Menu Function Controls
Using Menu Function Controls ACQUIRE Menu Function Controls You use the acquisition modes of a TDS1000B/TDS2000B oscilloscope to control how waveforms are acquired and displayed from the sample points taken on a signal. A TDS1000B/TDS2000B oscilloscope acquires 2500 sample points for each active channel during every acquisition of the respective signals.
Page 243 Using Menu Function Controls The Sample acquisition mode is the default acquisition mode. In this mode, the oscilloscope samples the signal in evenly spaced intervals to construct the waveform. You use the Peak Detect acquisition mode to detect glitches and high-speed noise in fast moving signals at slow time base settings.
Page 244: Using The Peak Detect Acquisition Mode
Using Menu Function Controls Using the Peak Detect Acquisition Mode You need to use Peak Detect when high-speed interference couples with electronic signals. Consider a situation where you need to test a complex signal that controls a mechanical robot. Glitches caused by various sources, such as light dimmers, motor controls, and design flaws, can interfere with the control signal and cause the robot to malfunction.
