Page 59: Application Examples
Application Examples This chapter presents six common oscilloscope applications: Taking simple measurements Analyzing signal detail Taking FFT measurements Triggering on a video signal Capturing a single-shot signal Saving data to a USB ﬂash drive TDS3000C Series Oscilloscope User Manual...
Page 60: Taking Simple Measurements
Application Examples Each application example highlights different features of the oscilloscope and gives you ideas about using the oscilloscope to solve test problems. Taking Simple Measurements You need to see a signal in a circuit, but you do not know the signal amplitude or frequency.
Page 61 Application Examples Selecting Automatic Measurements The oscilloscope can take automatic measurements of most displayed signals. To measure signal frequency and peak-to-peak amplitude, follow these steps: Push the Meas button to see the Select Measurement menu. Push the channel 1 button and then push the Select Measurement for Ch1 screen button.
Page 62 Application Examples To display the signals connected to channels 1 and 2, follow these steps: Push the channel 1 and 2 buttons to activate both channels. Push the Autoset button. To select measurements for the two channels, follow these steps: Push the Meas button to see the Select Measurement menu.
Page 63 Application Examples Calculate the ampliﬁer gain using the following equations: Customizing Your Measurements In this example you want to verify that the incoming signal to a piece of digital equipment meets its speciﬁcations. Speciﬁcally, the transition time from a low logic level (0.8 V) to a high logic level (2.0 V) must be 10 ns or less.
Page 64 Application Examples To select the rise time measurement, follow these steps: Push the Meas button to see the Select Measurement menu. Push the channel 1 button and then the Select Measurement for Ch1 screen button. Select the Rise Time measurement. Rise time is typically measured between the 10% and 90% amplitude levels of a signal;...
Page 65 Application Examples Next you want to see the pulses in the Measuring Speciﬁc Events. incoming digital signal, but the pulse widths vary so it is hard to establish a stable trigger. To look at a snapshot of the digital signal, follow this step: Push the Single Seq button to capture a single acquisition.
Page 66: Analyzing Signal Detail
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. TDS3000C Series Oscilloscope User Manual...
Page 67 Application Examples 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: Push the Acquire Menu button. Push the Mode bottom button. Select the Peak Detect acquisition mode.
Page 68 Application Examples Averaging reduces random noise and makes it easier to see detail in a signal. In the next example, a ring shows on the rising and falling edges of the signal when the noise is removed. Taking Cursor Measurements You can use the cursors to take quick measurements on a waveform.
Page 69 Application Examples Using Delay You are analyzing a pulse waveform and use the + Width measurement to measure the waveform pulse width. You notice that the measurement is not stable, which implies that there is jitter in the pulse width. TDS3000C Series Oscilloscope User Manual...
Page 70 Application Examples To use delay to see the jitter, follow these steps: Push the Delay button. Adjust the horizontal Position control to set the delay close to the nominal pulse width (210 μs). Push the Coarse button to make delay adjustments more quickly. Push the Coarse button again to ﬁne tune the delay time.
Page 71 Application Examples Adjust the horizontal Scale to a faster time base setting and increase the Waveform Intensity to see the jitter in the pulse width. NOTE. You can toggle the delay function on and off to view signal details at two different areas of interest.
Page 72 Application Examples Measuring Jitter To measure the peak-to-peak jitter, follow these steps: Push the Cursor button. Push the Function screen button. Select the V Bars cursors. Push the Bring Both Cursors On Screen screen button to quickly locate the cursors. Place one cursor at the ﬁrst falling edge and place the other cursor at the last falling edge.
Page 73: Taking Fft Measurements
Application Examples Taking FFT Measurements You can take FFT measurements to determine if low-level distortion is present, or to ﬁnd the source of noise in a mixed circuit. Detecting Distortion A pure sine wave can be input into an ampliﬁer to measure distortion; any ampliﬁer distortion will introduce harmonics in the ampliﬁer output.
Page 74 Application Examples Identifying the Source of Noise Noise in mixed digital/analog circuits can be easily observed with an oscilloscope. However, identifying the sources of the observed noise can be difﬁcult. The FFT waveform displays the frequency content of the noise. You may then be able to associate those frequencies with known system frequencies, such as system clocks, oscillators, read/write strobes, display signals, or switching power supplies.
Page 75 Application Examples In the next ﬁgure, notice the component at 31 MHz (ﬁgure label 1). This coincides with a 31 MHz memory strobe signal in the example system. There is also a frequency component at 62 MHz (label 2), which is the second harmonic of the strobe signal.
Page 76: Triggering On A Video Signal
Application Examples Triggering on a Video Signal You are testing the video circuit in a piece of medical equipment and need to display the video output signal. The video output is an NTSC standard signal. Use the video trigger to obtain a stable display. To trigger on the video ﬁelds, follow these steps: Push the Trigger Menu button.
Page 77 Application Examples Select Odd. Adjust the horizontal Scale to see a complete ﬁeld across the screen. Push the Acquire Menu button. Push the Horizontal Resolution screen button. Select Normal acquisition resolution. Normal acquisition resolution is the best choice to acquire a video ﬁeld signal because the signal contains a great amount of horizontal detail.
Page 78 Application Examples NOTE. The optional TDS3VID and TDS3SDI application modules add new video functions such as a video QuickMenu, video Autoset, trigger on custom scan rates, trigger on speciﬁc video lines, vectorscope (vectorscope supports component video only), video picture, trigger on analog HDTV signals, and view 601 digital video signals (TSD3SDI only).
Page 79: Capturing A Single-Shot Signal
Application Examples 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. The fastest you can open and close the relay is about once per minute so you need to capture the voltage across the relay as a single-shot acquisition.
Page 80 Application Examples The Single Seq button sets trigger parameters to the correct settings for a single-shot acquisition. Optimizing the Acquisition The initial acquisition shows the relay contact beginning to open at the trigger point. This is followed by a large spikes that indicate contact bounce and inductance in the circuit.
Page 81 Application Examples Using the Horizontal Zoom Function If you want to take a close look at a particular spot on the acquired waveform, use the horizontal zoom function. To look closely at the point where the relay contact ﬁrst begins to open, follow these steps: Push the zoom button Use the horizontal Position to place the expansion point close to where the relay contact begins to open.
Page 82: Saving Data To A Usb Flash Drive
Application Examples The zoom function works equally well when acquisition is running or is stopped. Horizontal position and scale changes affect only the display, not the next acquisition. Saving Data to a USB Flash Drive You need to do some work inside a remote site. You expect to use the oscilloscope to look at signal waveforms, to bring the waveform information back to the ofﬁce to complete a report, and to perform additional analysis.
Page 83 Application Examples When you need to capture screen images, it may be most convenient to ﬁrst save them to a USB ﬂash drive. Once on the USB ﬂash drive, you can load the screen images into a PC, print hard copies with a printer attached to your PC, or import the screen images into desktop publishing software to produce a report.
Page 84 Application Examples Naming Files. You should give ﬁles descriptive names so you can recognize them when you get back to the ofﬁce. You will be saving images of the control signal so you decide if CNTRL is a logical target ﬁle name to use.
Page 85 Application Examples Running the Test. To capture the control signal every few minutes, follow these steps: Display the signal, measurements, and menus as you want them to appear in the screen images. Push the hard copy button Repeat step 2 every few minutes until you are ﬁnished with the test. When you are ﬁnished, push Utility to see the list of sequential ﬁles that have been saved.
Page 86 Application Examples Select Spreadsheet File Format. The default target ﬁle, TEK?????.CSV, is now automatically highlighted. Push the Save To Selected File screen button to save the waveform. Push the File Utilities screen button to see the saved waveform ﬁle TEK00000.CSV in the USB ﬂash drive directory. TDS3000C Series Oscilloscope User Manual...

This setting determines the record length that is acquired and affects the other factors shown in the next table. Factor Normal Fast trigger Record length 10,000 points 500 points...
Page 96 Reference WaveAlert Waveform Anomaly Detection. WaveAlert provides a way to detect when a waveform deviates from a steady-state condition. WaveAlert monitors the current waveform acquisition and compares it to the previous DPO waveform acquisitions, using a sensitivity value to adjust the comparison tolerance. If the current acquisition exceeds the comparison tolerance, the oscilloscope considers the current acquisition as an anomaly.
Page 97 Reference Use the general purpose knob to set the comparison sensitivity value. As signal noise and intensity levels affect the displayed waveform, you will need to experiment with the sensitivity setting to reduce the number of false anomalies due to signal noise. Use the Waveform Intensity front-panel button to adjust the persistence of the anomaly waveform.
Page 98: Cursor

Page 144 Reference Alternating trigger uses the current trigger settings to trigger on all active channels; there is not a separate trigger setup for each channel. Therefore, the trigger settings must be able to trigger on all active signals in order to produce a stable triggered display. If one or more of the source signals do not meet the trigger settings, the oscilloscope either waits for that source channel to trigger (Normal trigger mode) or autotriggers (Auto trigger mode).
Page 145 Reference Logic Triggers Edge triggering can trigger on most signals, and is the default trigger type. Edge triggering sets the oscilloscope to trigger (acquire signal data) when a signal meets a speciﬁed signal slope and a single voltage-threshold condition. However, there are times when you need to trigger the oscilloscope on a more complex signal, or when two signals meet a condition to troubleshoot a problem.
Page 146 Reference Logic State. The actual state (true or false) of a signal depends on how you deﬁne its signal logic setting, which can be either high-true or low-true. Deﬁning a signal as high-true (H) means that signal levels above (more positive than) the threshold level are true, and signal levels below (more negative than) the threshold level are false.
Page 147 Reference The four logical comparison functions are AND, OR, NAND, and NOR: The AND function means that if both signal logic states are true, the condition is true, otherwise the condition is false. The OR function means if either or both signal logic states are true, the condition is true, otherwise the condition is false.
