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 thr feature: Autoset.
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.
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 basic concepts about trigger.
Trigger Source: The trigger can be generated with multiple sources. The most common one is the
input channel (alternative between CH1 and CH2). Whether the input signal is displayed or not, it
can trigger normal operations.
Trigger Type: The oscilloscope has six types of triggers: Edge, Video, Pulse Width, Slope,
Overtime and Alter.
➢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 Trigger performs a field or line trigger through standard video signals.
➢Pulse Width Trigger can trigger normal or abnormal pulses that meet trigger conditions.
➢Slope Trigger uses the rise and fall times on the edge of signal for triggering.
➢Overtime Trigger happens after the edge of signal reaches the set time.
➢Alter Trigger, as a feature of analog oscilloscopes, gives stable displays of signals at

Main Feature Description
DSO8000E Series HandHeld Oscilloscope User Manual 9
two different frequencies. Mainly it uses a specific frequency to switch between two
analog channels CH1 and CH2 so that the channels will generate alter trigger signals
through the trigger circuitry.
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 this 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 sequence 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 Pulse trigger, and then select a Coupling option.
Trigger Position: The horizontal position control establishes the time between 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 the
trigger slope control, press the TRIG MENU button, select an Edge trigger, and use the Slope
button to select rising or falling. The LEVEL button controls the trigger point is on which position of
the edge.
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. 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 this acquisition mode, the oscilloscope gets the maximum and minimum values of
Trigger slope can be rising or falling

Falling Edge
Trigger level can be
adjusted vertically

Main Feature Description
DSO8000E Series HandHeld Oscilloscope User Manual 10
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, noise will appear to be higher in this mode.
Average: In this acquisition mode, the oscilloscope acquires several waveforms, averages them,
and displays the resulting waveform. You can use this mode to reduce random noise.
Equivalent Acquisition: This kind of acquisition can be utilized for periodic 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 acquisition 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
TIME/DIV button to adjust the time base to a horizontal scale that suits your purpose.
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 will increase or decrease in size. Once the position
changes, the waveform will move up, down, right, or left.
The channel reference indicator (located on the left of the graticule) identifies each waveform on
the screen. It points to the ground level of the waveform record.
Vertical Scale and Position: The vertical position 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 you
push the VOLTS button to change the vertical scale of a waveform, the waveform display will
contract or expand vertically to the ground level.
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 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 clicking the TIME/DIV button. For example, you may want
to see just one cycle of a waveform to measure the overshoot on its rising edge. The oscilloscope
shows the horizontal scale as time per division in the scale readout. Since all active waveforms
use the same time base, the oscilloscope only displays one value for all the active channels.

Main Feature Description
DSO8000E Series HandHeld Oscilloscope User Manual 11
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 measurement.
Graticule: This method allows you to make a quick, visual estimate and take a simple
measurement through the graticule divisions and the scale factor.
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 follows:
6 divisions x 50mV/division = 300mV.
Cursor: This method allows you to take measurements by moving the cursors. Cursors always
appear in pairs and the displayed readouts are just their measured values. There are two kinds of
cursors: Amplitude Cursor and Time Cursor. The amplitude cursor appear as a horizontal broken
line, measuring the vertical parameters. The time cursor appear as a vertical broken line,
measuring the horizontal 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.
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. Automatic measurements show the measurement results by readouts
which are periodically updated with the new data acquired by the oscilloscope.

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 sampling 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 XY format.
