For Edge and Pulse triggers, the oscilloscope counts the rate at which trigger events occur to determine trigger frequency. The oscilloscope displays the frequency in the lower right corner of the screen. Source You can use the Trigger Source options to select the signal that the oscilloscope uses as a trigger.
Understanding Oscilloscope Functions Rising edge Falling edge Trigger level can be adjusted vertically Trigger can be rising or falling Acquiring Signals When you acquire a signal, the oscilloscope converts it into a digital form and displays a waveform. The acquisition mode defines how the signal is digitized, and the time base setting affects the time span and level of detail in the acquisition. Acquisition Modes There are three acquisition modes: Sample, Peak Detect, and Average. Sample.
Understanding Oscilloscope Functions Scaling and Positioning Waveforms You can change the display of waveforms by adjusting the scale and position. When you change the scale, the waveform display will increase or decrease in size. When you change the position, the waveform will move up, down, right, or left. The channel indicator (located on the left of the graticule) identifies each waveform on the display. The indicator points to the ground reference level of the waveform record.
Understanding Oscilloscope Functions the oscilloscope displays a waveform with a frequency lower than the actual input waveform, or triggers and displays an unstable waveform. Actual high-frequency waveform Apparent low-frequency waveform due to aliasing Sample points The oscilloscope accurately represents signals, but is limited by the probe bandwidth, the oscilloscope bandwidth, and the sample rate.

Understanding Oscilloscope Functions 28 TBS1000 Series Oscilloscopes User Manual
Application Examples This section presents a series of application examples. These simplified examples highlight the features of the oscilloscope and give you ideas for using it to solve your own test problems.
Application Examples Taking Simple Measurements You need to see a signal in a circuit, but you do not know the amplitude or frequency of the signal. You want to quickly display the signal and measure the frequency, period, and peak-to-peak amplitude. Using Autoset To quickly display a signal, follow these steps: 1. Push the 1 (channel 1 menu) button. 2. Push Probe ► Voltage ►Attenuation ► 10X. 3. If using P2220 probes, set their switches to 10X. 4. Connect the channel 1 probe tip to the signal.
Application Examples Taking Automatic Measurements The oscilloscope can take automatic measurements of most displayed signals. NOTE. If a question mark (?) appears in the Value readout, the signal is outside the measurement range. Adjust the Vertical Scale knob (volts/division) of the appropriate channel to decrease the sensitivity or change the horizontal Scale setting (seconds/division).
Application Examples CH1 Freq 1.000kHz CH1 Period 1.000ms CH1 Pk-Pk 5.04V CH1 Rise Time 2.611µs? CH1 Pos Width 500.
Application Examples Measuring Two Signals If you are testing a piece of equipment and need to measure the gain of the audio amplifier, you will need an audio generator that can inject a test signal at the amplifier input. Connect two oscilloscope channels to the amplifier input and output as shown next. Measure both signal levels and use the measurements to calculate the gain. CH1 Pk-Pk 2.
Application Examples 7. Push the second option button from the top; the Measure 2 Menu appears. 8. Push Source ► CH2. 9. Push Type ► Pk-Pk. 10. Push the Back option button. Read the displayed peak-to-peak amplitudes for both channels. 11.
Application Examples Using Autorange to Examine a Series of Test Points If you have a machine that is malfunctioning, you may need to find the frequency and RMS voltage of several test points, and compare these values to ideal values. You are not able to access front-panel controls since you need to use both hands when probing test points that are difficult to physically reach. 1. Push the 1 (channel 1 menu) button. 2.
Application Examples Taking Cursor Measurements You can use the cursors to quickly take time and amplitude measurements on a waveform. Measuring Ring Frequency and Amplitude To measure the ring frequency at the rising edge of a signal, follow these steps: 1. Push the Cursor button to see the Cursor Menu. 2. Push Type ► Time. 3. Push Source ► CH1. 4. Push the Cursor 1 option button. 5. Turn the multipurpose knob to place a cursor on the first peak of the ring. 6. Push the Cursor 2 option button. 7.
Application Examples Type Amplitude Source CH1 ΔV 640mV Cursor 1 1.46V Cursor 2 820mV Measuring Pulse Width If you are analyzing a pulse waveform and you want to know the width of the pulse, follow these steps: 1. Push the Cursor button to see the Cursor Menu. 2. Push Type ► Time. 3. Push Source ► CH1. 4. Push the Cursor 1 option button. 5. Turn the multipurpose knob to place a cursor on the rising edge of the pulse. 6. Push the Cursor 2 option button. 7.
Application Examples Type Time Source CH1 Δt 500.0µs 1/Δt 2.000kHz ΔV 1.38V Cursor 1 0.00s 0.98V Cursor 2 500µs -1.00V NOTE. The Positive Width measurement is available as an automatic measurement in the Measure Menu. (See page 88, Taking Measurements.) NOTE. The Positive Width measurement also displays when you select the Single-Cycle Square option in the AutoSet Menu. (See page 81, Square Wave or Pulse.
Application Examples 11. Turn the multipurpose knob to place a cursor at the point where the waveform crosses the second graticule line below center screen. This is the 10% level of the waveform. 12. Push the Cursor 2 option button. 13. Turn the multipurpose knob to place a cursor at the point where the waveform crosses the second graticule line above center screen. This is the 90% level of the waveform. The Δt readout in the Cursor Menu is the rise time of the waveform.
Application Examples Analyzing Signal Detail You have a noisy signal displayed on the oscilloscope and you need to know more about it. You suspect that the signal contains much more detail than you can now see in the display. Looking at a Noisy Signal The signal appears noisy and you suspect that noise is causing problems in your circuit. To better analyze the noise, follow these steps: 1. Push the Acquire button to see the Acquire Menu. 2. Push the Peak Detect option button.
Application Examples Averaging reduces random noise and makes it easier to see detail in a signal. In the example below, a ring shows on the rising and falling edges of the signal when the noise is removed. Capturing a Single-Shot Signal The reliability of a reed relay in a piece of equipment has been poor and you need to investigate the problem. You suspect that the relay contacts arc when the relay opens.
Application Examples Optimizing the Acquisition The initial acquisition shows the relay contact beginning to open at the trigger point. This is followed by a large spike that indicates contact bounce and inductance in the circuit. The inductance can cause contact arcing and premature relay failure. You can use the vertical, horizontal, and trigger controls to optimize the settings before the next single-shot event is captured.
Application Examples Measuring Propagation Delay You suspect that the memory timing in a microprocessor circuit is marginal. Set up the oscilloscope to measure the propagation delay between the chip-select signal and the data output of the memory device. Type Time Source CH1 Δt 20.00ns 1/Δt 50.00MHz ΔV 0.28V Cursor 1 50.0ns -0.20V Cursor 2 70.0ns 0.08V To set up to measure propagation delay, follow these steps: 1. Push the AutoSet button to trigger a stable display. 2.
Application Examples 8. Push the Cursor 2 option button. 9. Turn the multipurpose knob to place the second cursor on the data output transition. The Δt readout in the Cursor Menu is the propagation delay between the waveforms. The readout is valid because the two waveforms have the same horizontal scale (seconds/division) setting. Triggering on a Specific Pulse Width You are testing the pulse widths of a signal in a circuit.
Application Examples 1. Push the When option button to select ≠, <, or >. If there are any aberrant pulses that meet the specified When condition, the oscilloscope triggers. NOTE. The trigger frequency readout shows the frequency of events that the oscilloscope might consider to be a trigger, and may be less than the frequency of the input signal in Pulse Width trigger mode.
Application Examples NOTE. Most video systems use 75 ohm cabling. The oscilloscope inputs do not properly terminate low impedance cabling. To avoid amplitude inaccuracy from improper loading and reflections, place a 75 ohm feedthrough terminator (Tektronix part number 011-0055-02 or equivalent) between the 75 ohm coaxial cable from the signal source and the oscilloscope BNC input. Triggering on Video Fields Automatic. To trigger on the video fields, follow these steps: 1. Push the AutoSet button.
Application Examples Triggering on Video Lines Automatic. You can also look at the video lines in the field. To trigger on the video lines, follow these steps: 1. Push the AutoSet button. 2. Push the top option button to select Line to sync on all lines. (The AutoSet Menu includes All Lines and Line Number options.) Manual. An alternative method requires more steps, but may be necessary depending on the video signal. To use this method, follow these steps: 1.
Application Examples Using the Window Function to See Waveform Details You can use the window (zoom) function to examine a specific portion of a waveform without changing the main display. If you want to view the color burst in the previous waveform in more detail without changing the main display, follow these steps: 1. Push the Horiz button to see the Horizontal Menu and select the Main option. 2. Push the Window Zone option button. 3. Turn the horizontal Scale (seconds/division) knob and select 500 ns.
Application Examples Analyzing a Differential Communication Signal You are having intermittent problems with a serial data communication link, and you suspect poor signal quality. Set up the oscilloscope to show you a snapshot of the serial data stream so you can verify the signal levels and transition times. Because this is a differential signal, you use the Math function of the oscilloscope to view a better representation of the waveform. NOTE. Be sure to first compensate both probes.
Application Examples 6. Push the Operation option button and select -. 7. Push the CH1-CH2 option button to display a new waveform that is the difference between the displayed waveforms. 8. To adjust the vertical scale and position of the Math waveform, follow these steps: a. Remove the channel 1 and channel 2 waveforms from the display. b. Turn the channel 1 and channel 2 Vertical Scale and Vertical Position knobs to adjust the vertical scale and position of the Math waveform.
Application Examples To view the input and output of the circuit in an XY display, follow these steps: 1. Push the 1 (channel 1 menu) button. 2. Push Probe ► Voltage ►Attenuation ► 10X. 3. Push the 2 (channel 2 menu) button. 4. Push Probe ► Voltage ► Attenuation ► 10X. 5. If using P2220 probes, set their switches to 10X. 6. Connect the channel 1 probe to the input of the network, and connect the channel 2 probe to the output. 7. Push the AutoSet button. 8.
Application Examples 11. Turn the vertical Scale and vertical Position knobs to optimize the display. 12. Push Persist ► Infinite. As you adjust the ambient temperature, the display persistence captures the changes in the characteristics of the circuit. Data Logging You want to use the oscilloscope to record data from a source over time.
Application Examples Limit Testing You want to use the oscilloscope to monitor an active input signal against a template and to output pass or fail results by judging whether the input signal is within the bounds of the template. 1. Push the front-panel Utility button. 2. Select Limit Test from the resulting side menu to bring up the limit testing menu. 3. Select Source from the side menu to define the source of the waveform to compare against the limit test template. 4.
Application Examples of waveforms, number of violations, or the time in seconds at which to stop. You can also choose to stop the testing manually. 8. Push the Run/Stop Test button to toggle between starting and ending the limit test. After you end the test, the oscilloscope will display the test statistics on the screen. This includes the number of cases tested, the number of cases passed, and the number of cases failed.
Math FFT This chapter contains detailed information on how to use the Math FFT (Fast Fourier Transform). You can use the FFT Math mode to convert a time-domain (YT) signal into its frequency components (spectrum).
Math FFT 4. Turn the Vertical Scale (volts/division) knob to ensure that the entire waveform remains on the screen. The oscilloscope may display erroneous FFT results (by adding high frequency components) if the entire waveform is not visible. 5. Turn the Horizontal Scale (seconds/division) knob to provide the resolution you want in the FFT spectrum. 6. If possible, set the oscilloscope to display many signal cycles.
Math FFT Displaying the FFT Spectrum Push the Math button to display the Math Menu. Use the options to select the Source channel, Window algorithm, and FFT Zoom factor. You can display only one FFT spectrum at a time. Math FFT option Settings Comments CH3 1, CH4 1 Source CH1, CH2, Window Hanning, Flattop, Rectangular Selects the FFT window type; (See page 58, Selecting an FFT Window.
Math FFT Selecting an FFT Window Windows reduce spectral leakage in the FFT spectrum. The FFT assumes that the YT waveform repeats forever. With an integral number of cycles (1, 2, 3, ...), the YT waveform starts and ends at the same amplitude and there are no discontinuities in the signal shape. A non-integral number of cycles in the YT waveform causes the signal start and end points to be at different amplitudes.
Math FFT The Math FFT function includes three FFT Window options. There is a trade-off between frequency resolution and amplitude accuracy with each type of window. What you want to measure and your source signal characteristics will help you to determine which window to use.
Math FFT 60 TBS1000 Series Oscilloscopes User Manual
Math FFT Eliminating Aliases To eliminate aliases, try the following remedies: Turn the Horizontal Scale (seconds/division) knob to set the sample rate to a faster setting. Since you increase the Nyquist frequency as you increase the sample rate, the aliased frequency components appear at their proper frequency. If too many frequency components are shown on the screen, you can use the FFT Zoom option to magnify the FFT spectrum.
Math FFT Measuring an FFT Spectrum Using Cursors You can take two measurements on FFT spectrums: magnitude (in dB), and frequency (in Hz). Magnitude is referenced to 0 dB, where 0 dB equals 1 VRMS. You can use the cursors to take measurements at any zoom factor. To do so, follow these steps: 1. Push the Cursor button to see the Cursor Menu. 2. Push Source ► MATH. 3. Push the Type option button to select Magnitude or Frequency. 4. Use the multipurpose knob to move cursors 1 and 2.

Reference Maximum of 500 MS/s for 25 MHz and 40 MHz models Maximum of 1 GS/s for 60 MHz, 100 MHz or 150 MHz models At 100 ns and faster settings, this sample rate does not acquire 2500 points. In this case, a Digital Signal Processor interpolates points between the sampled points to make a 2500 point waveform record. Peak Detect. Use Peak Detect acquisition mode to detect glitches as narrow as 10 ns and to limit the possibility of aliasing.
Reference Single Button. Push the Single (single sequence) button when you want the oscilloscope to acquire a single waveform and then stop. Each time you push the Single button, the oscilloscope begins to acquire another waveform. After the oscilloscope detects a trigger it completes the acquisition and stops.
Reference The following conditions cause autorange to adjust settings: Too many or too few waveform periods for a clear display of the trigger source (except when in Vertical Only) Waveform amplitude too large or too small (except when in Horizontal Only) Ideal trigger level changes When you push the AutoRange button, the oscilloscope adjusts controls to produce a usable display of the input signal.
Reference The Autorange function is usually more useful than Autoset in the following situations: Analyzing a dynamically changing signal Quickly comparing a sequence of several signals without adjusting the oscilloscope. This is very useful if you need to use two probes at the same time, or if you need to use a probe in one hand and are holding something else in the other.
Reference Function Setting Vertical coupling DC (if GND was previously selected); AC for a video signal; otherwise, unchanged VOLTS/DIV Adjusted The Autoset function examines all channels for signals and displays corresponding waveforms. Autoset also determines the trigger source based on the following conditions: If multiple channels have signals, the oscilloscope displays the channel with the lowest frequency signal.
Reference Square Wave or Pulse When you use the Autoset function and the oscilloscope determines that the signal is similar to a square wave or pulse, the oscilloscope displays the following options: Square wave or Details Multi-cycle square Displays several cycles with appropriate vertical and horizontal scaling; the oscilloscope displays Pk-Pk, Mean, Period, and Frequency automatic measurements Single-cycle square Sets the horizontal scale to display about one cycle of the waveform; the oscilloscop
Reference Cursor Push the Cursor button to display the measurement cursors and Cursor Menu, and then use the multipurpose knob to change the position of a cursor.
