DSO1000B Series HandHeld Oscilloscope User Manual 8
Chapter 4 Main Feature Descripti on
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 Oscill oscope Setup
While operating the oscilloscope, you may oft en use thr feature: Autoset.
Autoset: This function can be used to adjust the horizontal and vertical scales of the oscillosc ope
automatically and s et t he trigg er coupling, type, pos ition, s lope, lev el and m ode, et c., 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 proper ly set up, the osc illos c ope can convert unstable dis plays or blank scr eens
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 (alter nat ive bet wee n CH1 and CH2) . W hether the inp ut sig nal is displa y ed or not, it
can trigger normal operations.
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 circ uits for triggering. It happens when the
input trigg er source crosses a specified level in a specified directio n.
Video Trigger performs a field or line tr igger through standard video signals.
Pulse Width Trigger can trigger normal or abnorm al puls es that meet trigger conditions.
Slope Tr igger 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.
Swap Trigger, as a feature of analog os cilloscopes, giv es stable displays of sig nals at
Main Feature Description
DSO1000B 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 g enerate swap trigger signals
thr oug h the trigger circuitry.
Trigger Mode: You can select the Auto or Norm al mode to def ine how the osc illosc ope acq uires
data when it does not detec t a trigger condition. Auto Mode performs t he acquisition freely i n
absence of valid tr igger. It allows the generation of untrig gered wav eforms with the time bas e set
to 80ms/div or slower. Normal Mode updates the displayed waveforms only when the
oscilloscope det ects a valid trigger condition. Before t his update, the oscill oscope still displa ys 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 singl e seq uence acq uisition, push the SINGLE SEQ button.
Trigger Coupling: Trigger Coupling determines which part of the sig nal will be delivered to the
trigger circ uit. 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 t he trigger point is on the risi ng or falling edge of a sig nal. 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 positio n 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 ac quisition. The real-time acquisition
has three modes: Normal, Peak Detect, and Average. The acquisition rate is affected by the
setting of tim e 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 var iations in the analog signal that m ay occur between two sam ples, which can
result in aliasing and may cause narr ow pulses to be missed. In such cases , yo u sho uld 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
Rising Edge
Falling Edge
Trigger level can be
adjusted vertically
Main Feature Description
DSO1000B Series HandHeld Oscilloscope User Manual 10
the input signal over each sam ple interval and uses these values to displa y the waveform. I n this
w ay, the oscilloscope can acquire and display t hose narrow pulses that may have otherwis e been
missed in Normal m ode. However, noise will appear t o be higher in this mode.
Average: In this acq uisition mode, the oscillosc ope acquires several wavef orms, aver ages them,
and displays the resulting waveform. You can use this mode to reduce random noise.
Equivalent Acquisition: This kind of acquisitio n can be utilized for periodic s ignals. In c ase t he
acquisition rat e is too low when us ing t he rea l-tim e acq uisition, the osc illoscope will use a fixed
rate to acquire data with a stationary tiny delay after each acquisition of a frame of data. After
repeating this acq uisition for N times, the oscilloscope will arrange the acquired N fr ames of data
by time to make up a new fram e of data. Then the waveform can be rec overed. 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 t hat suits your purpose.
4.4 Waveform Scal i n g and Positioning
The display of waveforms on the screen can be changed by adjusting their sc ale 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 i ndicator (locat ed on the left of the graticule) ide ntifies each wavef orm on
the screen. It points to the ground level of the waveform record.
Vertical Scale and Position: The vertic al position of a waveform can be changed by moving it up
and down on the screen. T o compare data, you may align a wavef orm over another. W hen 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 PO SITION 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 trigg er position and the screen center .
For example, if you want t o fi nd o ut the ca us e of a glitc h in yo ur tes t cir c uit, you should t rigg er on
the glitch and mak e t he pretr igger period long e nough to capt ure data befor e the gl itc h. Then you
can analyze the pretrigger data and perhaps find the cause. You are allowed to change the
horizontal s cale 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 overs hoot on its rising edge. The oscilloscope
shows the horizontal scale as time per division in the scale readout. S ince all active waveforms
use the same time base, the oscilloscope only displays one value for all the activ e channels.
Main Feature Description
DSO1000B Series HandHeld Oscilloscope User Manual 11
4.5 Waveform Measurement
The oscilloscope dis plays graphs of voltage versus t ime 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 throug h the graticule divisio ns 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 t he 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 m ethod allows you to take measurements by moving the cursors . Cursors always
appear in pairs and the displayed readouts are just their measured v alues. There ar e two kinds of
cursors: Amplitude Curs or and Time Curs or. The amplitude cursor appear as a horizontal brok en
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 gr aticule
and cursor measurements. Automatic measurements show the measurement results by readouts
which are periodical ly updated with the new data acquired by the oscilloscope.

5.3.1 Math FFT
This chapter elaborat es 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 f requency com ponents (s pectr um), and to
observe the followi ng types of signals:
Analyze harmonics in power cords;
Meas ure harmonic content and distortion in systems;
Characterize noise in DC power supplies;
Test impulse response of filters and systems;
Basic Operation
DSO1000B Series HandHeld Oscilloscope User Manual 19
Analyze vibration.
To use the Math FFT mode, perform the following tasks:
Set the source (time-domain) waveform;
Display the FFT spectrum;
Choos e a type of FFT window;
Adjust the sample rate to display the fundamental frequenc y and harmonics without aliasing;
Us e zoom controls to magnify the spectrum;
Use cursors to measure the spectrum.
5.3.1.1 Setting Time-domain Waveform
It is necessary to set the time-domain (YT) waveform before using the FFT mode. Follow the steps
below.
1. Push the AUTO button to display a YT waveform.
2. Click the Vertical Position key to vert ically m ove the YT waveform to the center (zer o division)
so as to ensure the FFT will display a tr ue DC value.
3. Click t he Hor iz o ntal Pos it io n ke y t o pos ition the part of the YT waveform to be analyzed i n the
center eight divisions of the screen. The oscilloscope uses the 2048 center points of the
time-domain waveform to calculate the FFT spectrum.
4. Click the VOLTS Key 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 comp onents.
5. Click the TIME/DIV key to provide the resolution you need in the FFT spectrum.
6. If possible, set the oscilloscope to display multiple signal cycles.
If you Click the TIME/DIV key to select a faster setting (fewer cycles), the FFT spectrum will
display a larger frequency range and reduce the poss ibility of FFT aliasing.
To set the FFT display, follow the steps below.
1. Push the M/R button;
2. Set the Operation optio n 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 trigg ered. This is especially true if the signal is periodic or random (such as
noise).
Note: You should trigger and position transient or burst wavef orms as cl ose as possible t o
the screen center.
Nyquist Frequency
Basic Operation
DSO1000B Series HandHeld Oscilloscope User Manual 20
The highest freq uency that any rea l-t im e digital osc illosc ope can m easure wit hout err or s is half of
the sample rate, which is called the Nyquist frequenc y. Frequency information beyond the Nyquist
fr equenc y is und ers ample d whic h bri ngs abo ut the F FT alia sing . The m ath func tio n can co nvert
the center 2048 points of the time-domain waveform to an FFT spectrum. The resulting FFT
spectrum contains 1024 points from DC (0Hz) to the Nyquist frequency. Usually, the screen
compresses the FFT spect rum horizontal ly t o 250 points, but you ca n use the FFT Zoom functio n
to expand the FFT spectrum so that you can clearly view the frequency components at each of the
1024 data points in the FFT spectrum.
Note: The oscilloscope’s verti cal response is a little bit larger than its bandwidth (60MHz,
100MHz or 200MHz, depending on the model; or 20MHz when the Bandwidth Limit option is
set to Limited). Therefore, the FFT spectrum can displ ay vali d frequen cy information above
the oscilloscope bandwidth. However, the amplitude information near or above the
bandwidth will not be accurate.

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 ...), the YT waveform starts and ends at the sam e amplitude and there are no dis continuit ies i n
the signal shape.
If the number of cycles is nonintegral, the YT waveform starts and ends at different amplitudes and
transitions betwee n the star t and end points will ca use disc ontinuit ies i n the signal that i ntrod uces
high-frequency transients.
Applying a window to the YT waveform changes t he waveform so that the start and stop values
are close to each other, which reduces the discontinuities.
Basic Operation
DSO1000B Series HandHeld Oscilloscope User Manual 22
The Math FFT function has three FFT Window options. There is a trade-off between frequenc y
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.

5.3.1.4 FFT Aliasing
Problems occur when the time-domain waveform acquired by the oscilloscope contains frequency
components higher than t he Nyquist frequency. The frequency components abov e the Nyquist
frequency will be undersampled and displayed as lower frequency components that ‘fold back’
from the Nyquist frequency. These erroneous components are called ali ases.
5.3.1.5 Eliminating Aliases
To eliminate aliases, use the followi ng methods.
Click the TIME/DIV key to set a faster sample rate. Bec ause the Nyquist fr eq uency increas es
as you increase the sample rate, the aliased frequency components will be displayed c orrect.
If too many frequency com ponents appear on the sc r een, you may use the FFT Zoom option
to magnify the FFT spectrum.
If t here is no need to observe the frequency components above 20MHz, set the Bandwidth

the rig ht is at the N yquist frequency.
You magnifies the FFT spect rum to the center gratic ule line when you change the zoom factor.
That is, the axis for horizontal magnification is the center graticule line. Click the Horizontal
Position Key to move the FFT spectrum to the right.
Vertical Zoom and Position
When the FFT spectrum is being displayed, the channel vertical keys become the zoom and
position controls corresponding to their respective channels. The VOLTS key provides the
following zoom f actors: X1(default), X 2, X5 and X10. T he FFT spectr um is magnified v ertic ally to

Normal: For the oscillosc ope model with the bandwidth of 100 MHz, the maxim um sample rate is
1GS/s. For time base with insufficient sample rate, you may use the Sine Interpolation Algorithm to
interpolate points between sampled points to produce a complete waveform record (4K by
default).
Peak Detect: Use this m ode to detect glitches w ithin 10ns and to l imit the poss ibility of aliasi ng.
This mode is valid at the TIME/DIV setting of 4µs/div or slower. Once you set the TIME/DIV setting
to 4µs/div or faster, the acquisition mode will change to Norm al because the sample rat e is fast
enough that Peak Detect is unnecessary. The oscilloscope does not display a mess age to tell you
that the mode has been changed to Normal.
Average: Use this mode to reduce random or uncorr elated noise in the signal to be displayed.
Acquire data in Normal mode and then average a great number of waveforms. Choose the
number of acquisitio ns (4, 16, 64 or 128) to average for the waveform.
Stopping the Acquisition: When you are running the acq uisition, the waveform displa y is live.

Chapter 8 Troubleshooting
8.1 Probl em Set t lement
1. If the oscilloscope does not start up at power on, fo ll ow these steps:
1） Check the power cord to verify it has been connect ed properly;
2） Check the power on/off button to ensure it has been pushed;
3） Then restart the oscilloscope.
Contact your local HANTEK distributor or directly keep touch with HANTEK Technical Support
department if the osc illos cope still can not be turned o n normally.
2. If there is no display of waveforms on the screen when the osci lloscope is turned on,
follow these steps:
1） Check the probe to assure its proper connection to the input BNC;
2） Check the channel swit ch (s uch as CH1, CH2 menu buttons) t o make sure it has been turned
on;
3） Check the input s ignal to verify it has been c onnected to the probe correctly;
4） Affirm that all measured circuits have sig nals to output;
5） Turn up the magnitude for DC sig nals with large magnitude;
6） In addition, you may press the Auto Measure button to perform an automatic detection of
signals a t first.
Contact HANTEK Technical Support department in time if t here is still no display of waveforms.
3. If the waveform of the i nput signal is distorted seriou sly, follow these steps:
1） Check the probe to assure its proper connect ion to t he channel BNC ;
2） Check the probe to assure its good connection to the m easured object;
3） Check the probe t o verify it has been well calibrat ed. Otherwise, refer to t he content about
calibration desc ribed in this manual.
4. If the waveform is rolling continuously on the screen but can not be triggered, follow
these steps:
1） Check the trigger source to make sure it consistent with the input chan nel;
2） Check the trigger level to assure its correct adjustment.
3） Check the tr igger mode to confirm it is a right choice for the input signal. The default tr igger
mode is edge trigger. However, it is not suitable for all kinds of input signals.
