Page 31: Setting Up The Oscilloscope
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.
Page 32: Default Setup
Understanding Oscilloscope Functions Default Setup The oscilloscope is set up for normal operation when it is shipped from the factory. This is the default setup. To recall this setup, push the DEFAULT SETUP button. To view the default settings, refer to Appendix D: Default Setup.
Page 33: Source
Understanding Oscilloscope Functions When you push the RUN/STOP or SINGLE SEQ buttons to start an acquisition, the oscilloscope goes through the following steps: 1. Acquires enough data to fill the portion of the waveform record to the left of the trigger point. This is also called the pretrigger. 2.
Page 34: Types
Understanding Oscilloscope Functions Types The oscilloscope provides three types of triggers: Edge, Video, and Pulse Width. Modes You can select a Trigger Mode to define how the oscilloscope acquires data when it does not detect a trigger condition. The modes are Auto and Normal.
Page 35: Position
Understanding Oscilloscope Functions Position The horizontal position control establishes the time between the trigger and the screen center. Refer to Horizontal Scale and Position; Pretrigger Information on page 19 for more information on how to use this control to position the trigger. Slope and Level The Slope and Level controls help to define the trigger.
Page 36: Acquiring Signals
Understanding Oscilloscope Functions 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.
Page 37: Time Base
Understanding Oscilloscope Functions Time Base The oscilloscope digitizes waveforms by acquiring the value of an input signal at discrete points. The time base allows you to control how often the values are digitized. To adjust the time base to a horizontal scale that suits your purpose, use the SEC/DIV knob.
Page 38: Horizontal Scale And Position; Pretrigger Information
Understanding Oscilloscope Functions Horizontal Scale and Position; Pretrigger Information You can adjust the HORIZONTAL POSITION control to view waveform data before the trigger, after the trigger, or some of each. When you change the horizontal position of a waveform, you are actually changing the time between the trigger and the center of the display.
Page 39 Understanding Oscilloscope Functions Time Domain Aliasing. Aliasing occurs when the oscilloscope does not sample the signal fast enough to construct an accurate waveform record. When this happens, the oscilloscope displays a waveform with a frequency lower than the actual input waveform, or triggers and displays an unstable waveform.
Page 40 Understanding Oscilloscope Functions Oscilloscope models with 60 MHz or 100 MHz bandwidth sample at rates up to 1 GS/s. Models with 200 MHz bandwidth sample at rates up to 2 GS/s. In both cases, these maximum sample rates are at least ten times the bandwidth.
Page 41 Understanding Oscilloscope Functions The next table lists the time bases that you should use to avoid aliasing at various frequencies and the respective sample rate. At the fastest SEC/DIV setting, aliasing is not likely to occur due to the bandwidth limitations of the oscilloscope input amplifiers. Settings to avoid aliasing in Sample mode Maximum Time base...

Page 43: Taking Measurements
Understanding Oscilloscope Functions Taking Measurements The oscilloscope displays graphs of voltage versus time and can help you to measure the displayed waveform. There are several ways to take measurements. You can use the graticule, the cursors, or an automated measurement. Graticule This method allows you to make a quick, visual estimate.
Page 44: Cursors
Understanding Oscilloscope Functions Cursors This method allows you to take measurements by moving the cursors, which always appear in pairs, and reading their numeric values from the display readouts. There are two types of cursors: Voltage and Time. When you use cursors, be sure to set the Source to the waveform on the display that you want to measure.

Reference Vertical You can use the vertical controls to display waveforms, adjust vertical scale and position, and set input parameters. Refer to page 93 for the vertical math descriptions. Channel Vertical Menus There is a separate vertical menu for each channel. Each option is set individually for each channel.
Page 132 Reference NOTE. The oscilloscope vertical response rolls off slowly above its bandwidth (60 MHz, 100 MHz, or 200 MHz, depending on the model, or 20 MHz when the Bandwidth Limit option is set to On). Therefore, the FFT spectrum can show valid frequency information higher than the oscilloscope bandwidth.

Page 135: Setting Up The Time-Domain Waveform
Math FFT Setting Up the Time-Domain Waveform Before you use FFT mode, you need to set up the time-domain (YT) waveform. To do so, follow these steps: 1. Push AUTOSET to display a YT waveform. 2. Turn the VERTICAL POSITION knob to move the YT waveform to the center vertically (zero divisions).
Page 136 Math FFT To set up the FFT display, follow these steps: 1. Push the MATH MENU button. 2. Set the Operation option to FFT. 3. Select the Math FFT Source channel. In many cases, the oscilloscope can produce a useful FFT spectrum even if the YT waveform is not triggered.
Page 137: Displaying The Fft Spectrum

Page 139: 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.
Page 140 Math FFT Applying a window to the YT waveform changes the waveform so that the start and stop values are close to each other, reducing the discontinuities. Time-domain (YT) waveform Center 2048 data points × Point-by-point multiply Window function (Hanning) YT waveform after windowing With windowing...
Page 141 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 help you to determine which window to use.
Page 142 Math FFT Nyquist frequency (one-half sample rate) Frequency Aliased frequencies Actual frequencies Eliminating Aliases To eliminate aliases, try the following remedies: H Turn the SEC/DIV 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 should appear at their proper frequency.
Page 143: Magnifying And Positioning An Fft Spectrum
Math FFT H If you do not need to view frequencies components above 20 MHz, set the Bandwidth Limit option to On. H Put an external filter on the source signal to bandwidth limit the source waveform to frequencies below that of the Nyquist frequency.
Page 144 Math FFT When you change the zoom factor, the FFT spectrum is magnified about the center graticule line. In other words, the axis of horizontal magnification is the center graticule line. Turn the HORIZONTAL POSITION knob clockwise to move the FFT spectrum to the right.
Page 145: Measuring An Fft Spectrum Using Cursors
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 V . You can use the cursors to take measurements at any zoom factor.
