Main Feature Description Chapter 4 Main Feature Description This chapter provides some general information that you need to learn before using an oscilloscope. It contains: 1. Oscilloscope setup 2. Trigger 3. Data acquisition 4. Waveform scaling and positioning 5. Waveform measurement 4.1 Oscilloscope Setup While operating the oscilloscope, you may often use three features: Autoset, saving a setup and recalling a setup. Hereinafter they are introduced one by one.
Main Feature Description trigger channel or the AC power line (only for Edge triggers). The source with the AC power line shows the frequency relationship between the signal and the AC commercial power. Trigger Type: The oscilloscope has six types of triggers: Edge, Video, Pulse Width, Slope, Overtime and Swap. Edge Trigger uses the analog or digital test circuits for triggering. It happens when the input trigger source crosses a specified level in a specified direction.
Main Feature Description 4.3 Data Acquisition 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.
Main Feature Description 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 position and the screen center. For example, if you want to find out the cause of a glitch in your test circuit, you should trigger on the glitch and make the pretrigger period long enough to capture data before the glitch.
Main Feature Description Cursor Cursor Automatic Measurement: The oscilloscope performs all the calculations automatically in this mode. As this measurement uses the waveform record points, it is more precise than the graticule and cursor measurements.
Basic Operation Chapter 5 Basic Operation The front panel of the oscilloscope is divided into several functional areas. In this chapter we will give a quick overview of all control buttons and knobs on the front panel as well as the displayed information on the screen and relative testing operations. The figure below illustrates the front panel of the DSO-1062D-VGA digital oscilloscope. Front Panel of DSO-1062D-VGA 5.

Basic Operation Dual-window Mode (Full Screen) Location of expanded window data in memory Major Window Minor Window (Expanded Window) Multi-functional Knob 3.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.
Basic Operation 1. For more information of the trigger holdoff, see Section Trigger Controls. 2. In single-window mode, press F0 to hide or show the menus on the right side. The dual-window mode does not support the menu hiding function. 5.2.1 Scan Mode Display (Roll Mode) With the SEC/DIV control set to 80ms/div or slower and the trigger mode set to Auto, the oscilloscope works in the scan acquisition mode.
Basic Operation 20MHz Bandwidth Limit Unlimited Limited VOLTS/DIV Coarse Fine 1X 10X 100X 1000X Off On Probe Attenuation Invert Limits the bandwidth to reduce display noise; filters the signal to eliminate noise and other unnecessary HF components. Selects the resolution of the VOLTS/DIV knob. Coarse defines a 1-2-5 sequence. Fine changes the resolution to small steps between the Coarse settings. Selects a value according to the probe attenuation factor so as to ensure correct vertical readouts.
Basic Operation 5.3.1 Math FFT This chapter elaborates how to use the Math FFT (Fast Fourier Transform). You can use the Math FFT mode to convert a time-domain (YT) signal into its frequency components (spectrum), and to observe the following types of signals: Analyze harmonics in power cords; Measure harmonic content and distortion in systems; Characterize noise in DC power supplies; Test impulse response of filters and systems; Analyze vibration.
Basic Operation 2. Set the Operation option to FFT; 3. Select the Math FFT Source channel. In many situations, the oscilloscope can also generate a useful FFT spectrum despite the YT waveform not being triggered. This is especially true if the signal is periodic or random (such as noise). Note: You should trigger and position transient or burst waveforms as close as possible to the screen center.
Basic Operation 1 Fundamental frequency component Frequency component 5 2 3 4 1. Frequency at the center graticule line 2. Vertical scale in dB per division (0dB=1VRMS) 3. Horizontal scale in frequency per division 4. Sample rate in number of samples per second 5. FFT window type 5.3.1.3 Selecting FFT Window Using windows can eliminate the spectral leakage in the FFT spectrum. The FFT algorithm assumes that the YT waveform repeats all the time. When the number of cycles is integral (1, 2, 3 ...
Basic Operation 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.
Basic Operation 5.3.1.4 FFT Aliasing Problems occur when the time-domain waveform acquired by the oscilloscope contains frequency components higher than the Nyquist frequency. The frequency components above the Nyquist frequency will be undersampled and displayed as lower frequency components that ‘fold back’ from the Nyquist frequency. These erroneous components are called aliases. 5.3.1.5 Eliminating Aliases To eliminate aliases, use the following methods.
Basic Operation the marker M (math waveform reference point on the left edge of the screen). Turn the VERTICAL POSITION knob clockwise to move up the spectrum. 5.3.1.7 Using Cursors to Measure FFT Spectrum You may use cursors to take two measurements on the FFT spectrum: amplitude (in dB) and frequency (in Hz). Amplitude is referenced to 0db that equals 1VRMS here. You may use cursors to measure at any zoom factor. Push the CURSOR button, choose the Source option and then select Math.
Basic Operation 1. Level It sets the amplitude level the signal must cross to cause an acquisition when using the Edge or Pulse Width trigger. 2. Set to 50% The trigger level is set to the vertical midpoint between the peaks of the trigger signal. 3. Force Trigger Used to complete an acquisition regardless of an adequate trigger signal. This button becomes useless if the acquisition is already stopped. 4. TRIG MENU Push this button to display trigger menus. The edge trigger is in common use.
Basic Operation Options Trigger Type Edge Video Pulse Slope Swap Overtime Settings Source CH1 CH2 EXT EXT/5 AC Line Mode Auto Normal Coupling AC DC HF Reject LF Reject Comments By default the oscilloscope uses the edge trigger which triggers the oscilloscope on the rising or falling edge of the input signal when it crosses the trigger level (threshold). Select the input source as the trigger signal. CH1, CH2: No matter the waveform is displayed or not, a certain channel will be triggered.
Basic Operation Note: When you choose Normal Polarity, the trigger always occurs on negative-going sync pulses. If the video signal contains positive-going sync pulses, use the Inverted Polarity option. Pulse Width Trigger You can use it to trigger on aberrant pulses. Options Settings Comments With Pulse highlighted, the trigger occurs on pulses that meet the trigger condition (defined by the Source, When and Set Pulse Width options).
Basic Operation or not equal to the specified pulse width. ＜, ＞: Triggers the oscilloscope when the source signal pulse width is less than or greater than the specified pulse width. Slope Trigger: Judges trigger according to the time for rising or falling, more flexible and accurate than the Edge trigger. Options Settings Comments Slope Source CH1 CH2 EXT EXT5 Select the input source as the trigger signal. Slope Rising Falling Select the slope type of signal.
