Main Feature Description

Chapter 4 Main Feature Description

This chapter provides some general information that you need to learn before using an oscilloscope. It cont ains:
1. Oscilloscope setup
2. Trigger
3. Data acquisition
4. Wavefor m sc al ing 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. Hereinaf ter they are introduced one by one.
Autoset: This function can be used to adjust the horizontal and vertical scales of the 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.) You can save 10 settings permanently in the oscilloscope and reset
them as necessary. Recalling a Setup: The oscilloscope can recall any of your saved setups or the default factory
setup. Default Setup: The oscilloscope is preset for normal operations when it is shipped from the
factory. This is the default setup. You may recall this setup at any time for your requirements. To view the default settings, refer to
Section 5.6.3.

4.2 Trigger

The trigger determines when the oscilloscope begins to acquire data and display a waveform. Once a trigger is properly set up, the oscilloscope can convert unstable displays or blank screens to meaningful waveforms. Here introduce some bas i c concepts about trigger.
Trigger Source: Th e trigg er can be ge nerated w ith multi ple sources . The mos t common o ne is th e input channel (alternative between CH1 and CH2). Whether the input signal is displayed or not, it can trigger normal operations. Also the trigger source can be any signal connected to an external
DSO-1062D Digital Oscilloscope User Manual 9
Main Feature Description
Trigger slope can be rising or falling
Rising Edge
Falling Edge
Trigger level can be adjusted vertically
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 t he AC co m mercial 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.
Video T r igger performs a fie ld or l ine trigger through standard video signals.
Pulse Width Trigger can trigger normal or abnorma l pulses t hat meet trigger conditions.
Slope Trigger uses the rise and fall times on the edge of signal for t r iggering.
Overtime Trigger happens after the edge of signal reaches the set time.
Swap Trigger, as a feature of analog oscilloscopes, gives stable displays of signals at
two different frequencies. Mainly it uses a specific frequency to switch between two analog channels CH1 and CH2 so that the channels will generate swap trigger signals through the trigger cir cuitry.
Trigger Mode: You can select the Auto or Normal mode to define how the oscilloscope acquires data when it does not detect a trigger condition. Auto Mode performs the acquisition freely in absence of valid trigger. It allows the generation of untriggered waveforms with the time base set to 80ms/div or slower. Normal Mode updates the displayed waveforms only when the oscilloscope detects a valid trigger condition. Before t his update, the oscilloscope still displays the old waveforms. This mode shall be used when you want to only view the effectively triggered waveforms. In this mode, the oscilloscope displays waveforms only after the first trigger. To perform a single seque nce acquisition, push the SINGLE SEQ button.
Trigger Coupling: Trigger Coupling determines which part of the signal will be delivered to the trigger circuit. This can help to obtain a stable display of the waveform. To use trigger coupling, push the TRIG MENU button, select an Edge or Puls e trigger, and then select a Coupling opti on.
Trigger Position: The horizontal position control establishes the time betw een the trigger position and the screen center.
Slope and Level: The Slope and Level controls help to define the trigger. The Slope option determines whether the trigger point is on the rising or falling edge of a signal. To perform t he trigger slope control, press the TRIG MENU button, select an Edge trigger, and use the Slope button to select rising or falling. The TRIGGER LEVEL knob controls the trigger point i s on whi ch position of the edge.
DSO-1062D Digital Oscilloscope User Manual 10
Main Feature Description

4.3 Data A cquisition

When you acquire an analog signal, the oscilloscope will convert it into a digital one. There are two kinds of acquisition: Real-time acquis ition and Equival ent acquis ition. The real-ti me acquisiti on 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 spac ed intervals to establish the waveform. This mode accurately represents signals in most time. However, it does not acquire rapid variations in the analog signal that may occur between two samples, which can result in aliasing and may cause narrow pulses to be missed. In such cases, you should use the Peak Detect mode to acquire data.
Peak Detect: In thi s ac quisitio n mod e, t he osci llosco pe gets the maximum and minimum values of the input signal over each sample interval and uses these values to display the waveform. In this way, the oscilloscope can acquire and display those narrow pulses that may have otherwise been missed in Normal mode. However, nois e w il l appear to be higher in this mode.
Average: In this acquisition mode, the oscilloscope acquires several waveforms, averages them, and displays the resultin g w aveform. You can use this mode to reduce random noise.
Equivalent Acquisition: This kind of acquisition can be utilized for periodi c signals. In case the acquisition rate is too low when using the real-time acquisition, the oscilloscope will use a fixed rate to acquire data with a stationary tiny delay after each acquisition of a frame of data. After repeating this acquisition for N times, the oscilloscope will arrange the acquired N frames of data by time to make up a new frame of data. Then the waveform can be recovered. The number of times N is related to the equivalent acquis ition rate.
Time Base: The oscilloscope digitizes waveforms by acquiring the value of an input signal at discrete points. The time base helps to control how often the values are digitized. Use the SEC/DIV knob to adjust the time base to a hor iz ontal scale that suits your pur pose.

4.4 Waveform Scaling and Positioning

The display of waveforms on the screen can be changed by adjusting their scale and position. Once the scale changes, the waveform display w ill increase or decrease i n siz e. Once the position changes, the waveform will move up, dow n, r ight, or left.
The channel reference indicator (located on the left of the graticule) identifies each waveform on the screen. It points to the ground lev el o f the waveform record.
Vertical Scale and Posi t ion: The vertical posit ion of a waveform can be changed by moving it up and down on the screen. To compare data, you may align a waveform over another. When yo u push the VOLTS/DIV button to change the vertical scale of a waveform, the waveform display will contract or expand vertica lly t o t he gr ound level.
Horizontal Scale and Position: Pretrigger Information
DSO-1062D Digital Oscilloscope User Manual 11
Main Feature Description
You can adjust the HORIZONTAL POSITION control to view waveform data before the trigger, after the trigger, or some of eac h. When you change the horiz ontal pos ition of a wav eform, you ar e actually changing the time bet ween 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. Then you can analyze the pretrigger data and perhaps find the cause. You are allowed to change the horizontal scale of all the waveforms by turning the SEC/DIV knob. For exam ple, you may want to see just one cycle of a waveform to measure the overshoot on its rising edge. The osci lloscope shows the horizontal scale as time per division in the scale readout. Since all active waveforms use the same time base, the osc il loscope only displays one value for all the active channels.

4.5 Waveform Measurement

The oscilloscope displays graphs of voltage versus time and can help to measure the displayed waveform. There are several ways to take measurements, using the graticule, the cursors or performing an automatic me asurement.
Graticule: This method allows you to make a quick, visual estimate and take a simple measurement through the graticule divisions and the sc al e fa c t or .
For example, you can take simple measurements by counting the major and minor graticule divisions involved and multiplying by the scale factor. If you counted 6 major vertical graticule divisions between the minimum and maximum values of a waveform and knew you had a scale factor of 50mV/division, you could easily calculate your peak-to-peak voltage as fo llows:
6 divisions x 50mV/division = 300mV. Cursor: This method allows you to take measure m ent s by moving the cursors. Cursors always
appear in pairs and the displayed r eadouts are just their measur ed values. There are two kinds of cursors: Amplitude Curs or and Time Cursor. The am plitude cursor appear as a horizontal broken line, measuring the vert ical parameters. The time cur s or appear as a vertical broken line, measuring the horizonta l parameters.
When using cursors, please make sure to set the Source to the waveform that you want to measure on the screen. To use cursors, push the CURSOR button.

5.1.1 XY Format

The XY format is used to analyze phase differences, such as those represented by Lissajous patterns. The format plots the voltage on CH1 against the voltage on CH2, where CH1 is the horizontal axis and CH2 is the vertical axis. The oscilloscope uses the untriggered Normal acquisition mode and displays data as dots. The sampling rate is fixed at 1 MS/s.
The oscilloscope can acquire waveforms in YT format at any sam pling rate. You may view the same waveform in XY format. To perform this operation, stop the acquisition and change the display format to XY.
The table below shows how to operate some controls in X Y format.

5.2 Horizontal Controls

Use the horizontal controls to change the horizontal scale and position of waveforms. The horizontal position readout shows the time represented by the center of the screen, using the trigger time as zero. When you c hange the horizontal scale, the waveform will expand or contract to the screen center. The readout near the upper right of the screen shows the current horizontal position in second. M represents ‘Main Time Base’, and W indicates ‘W indow Time Base’. The oscilloscope also has an arrow icon at the top of the graticu le to indicate the horizontal p osition.

5.3.1 Math FFT

This chapter elaborates how to use the Mat h 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 t ypes of signals:
Analyze harmonics in power cords; Measure harmonic content and distort i on i n s ystems; Characterize noise in DC power sup pl ies; Test impulse response of filters and systems; Analyze vibration.
To use the Math FFT mode, perfor m the following tasks:
Set the source (time-domain) wav ef or m; Display the FFT spectrum; Choose a type of FFT window; Adjust the sample rate to display the fu ndamental frequency and harmonics without aliasing; Use zoom controls to magnify t he spect r um; Use cursors to measure the spectr um.
5.3.1.1 Setting Time-domain Waveform
It is necessary to set the time-domain (YT) waveform before us ing the FFT mode. Fol low the step s below.
1. Push the AUTOSET but ton to display a Y T waveform.
2. Turn the VERTICAL POSITION knob to vertically move the YT waveform to the center (zero division) so as to ensure the FFT will display a tr ue D C value.
3. Turn the HORIZONTAL POSITION knob to position the part of the YT waveform to be analyzed in the center eight divisions of the screen. The oscilloscope uses the 2048 center points of the time-dom ain waveform to calculate the FFT spectrum.
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 SE C/DIV knob to provide the resolution you need in the FFT spectrum.
6. If possible, set the oscillos cope t o display multiple signal cycles.
If you turn the SEC/DIV kn ob to se lect a faster set ting ( fewer cycl es), the FF T s pectru m will display a larger frequency range and r educe the possibility of FFT aliasing.
To set the FFT display, follow t he st eps below.
1. Push the MATH MENU bu t ton;
