oscilloscope automatically and set the trigger coupling, type, position, slope, level and mode, etc., to acquire a stable waveform display. Saving a Setup: By default, the oscilloscope will save the setup each time before being closed, and automatically recall the setup once being turned on. (Note: If you modify the setup, please wait for more than 5 seconds before turning off the oscilloscope to ensure the proper storage of new settings.
Multi-functional Knob 2.SEC/DIV Knob: Used to change the horizontal time scale so as to magnify or compress the waveform horizontally. If the waveform acquisition is stopped (by using the RUN/STOP or SINGLE SEQ button), the SEC/DIV control will expand or compress the waveform. In dual-window mode, push this knob to select major or minor window. When the major window is selected, this knob provides the same functions as it provides in single-mode window.
Position Volt/div 1. Vertical Position Knob: Move the channel waveform up and down on the screen. In dual-window mode, move the waveforms in both windows at the same time in a same direction. Push this knob to return waveforms to the vertical center position on the screen. Two channels correspond to two knobs. 2. VOLTS/DIV Knob Control the oscilloscope to magnify or attenuate the source signal of the channel waveform.
Probe Attenuation 1X 10X 100X 1000X Selects a value according to the probe attenuation factor so as to ensure correct vertical readouts. Reduce bandwidth to 6MHz when using a 1X probe. Invert Off On Inverts the waveform relative to the reference level. Coupling If the channel adopts a DC coupling mode, you can quickly measure the DC component of the signal by observing the difference between the waveform and the signal ground.
Zoom: Use the FFT Zoom button to adjust the window size. Scale: x1, x2, x5, x10. Note: All selected menus are highlighted in orange. 2.7.2 Math FFT This chapter elaborates how to use the Math FFT (Fast Fourier Transform).
4. Turn the VOLTS/DIV knob to ensure the entire waveform remains on the screen. If the entire waveform is invisible, the oscilloscope may display wrong FFT results by adding high-frequency components. 5. Turn the SEC/DIV knob to provide the resolution you need in the FFT spectrum. 6. If possible, set the oscilloscope to display multiple signal cycles.
2.7.2.2 Displaying FFT Spectrum Push the MATH MENU button to display the Math menu. Use the options to select the Source channel, the Window algorithm and the FFT Zoom factor.

For more information FFT Zoom X1, X2, X5, X10 Change the horizontal magnification of the FFT display.
Applying a window to the YT waveform changes the waveform so that the start and stop values are close to each other, which reduces the discontinuities. The Math FFT function has three FFT Window options. There is a trade-off between frequency resolution and amplitude accuracy for each type of window. You shall determine which one to choose according to the object you want to measure and the source signal characteristics.
2.7.2.5 Eliminating Aliases To eliminate aliases, use the following methods. Turn the SEC/DIV knob to set a faster sample rate. Because the Nyquist frequency increases as you increase the sample rate, the aliased frequency components will be displayed correct. If too many frequency components appear on the screen, you may use the FFT Zoom option to magnify the FFT spectrum. If there is no need to observe the frequency components above 20MHz, set the Bandwidth Limit option to Limited.

again to acquire another waveform. When you acquire an analog signal, the oscilloscope will convert it into a digital one. There are two kinds of acquisition: Real-time acquisition and Equivalent acquisition. The real-time acquisition has three modes: Normal, Peak Detect, and Average. The acquisition rate is affected by the setting of time base. Normal: In this acquisition mode, the oscilloscope samples the signal in evenly spaced intervals to establish the waveform.
Options Settings Comments Acquire and accurately display most waveforms. Normal Detect glitches and eliminate the possibility of Mode Peak Detect aliasing. (Real Time) Average Reduce random or uncorrelated noise in signal HR display. The number of averages is selectable.
Peak Detect: Use this mode to detect glitches within 10ns and to limit the possibility of aliasing. This mode is valid at the SEC/DIV setting of 4µs/div or slower. Once you set the SEC/DIV setting to 4µs/div or faster, the acquisition mode will change to Normal because the sample rate is fast enough that Peak Detect is unnecessary. The oscilloscope does not display a message to tell you that the mode has been changed to Normal.
2.12 DISPLAY The waveform display is affected by settings of the oscilloscope. A waveform can be measured once it is captured. The different styles to display a waveform on the screen give significant information about it. There are two modes to display waveforms Single-window and Dual-window.
