Repeat above steps for CH2 to make sure both channels are functional.
3.4 Adjust your Probes
The Probe supplied is a pair of Passive Probe with x1 and x10 attenuation and it is
adjustable. It’s important to adjust the compensation whenever you use x10 for testing
and reduce the chance to have a wrong measurement. Here are the procedures to you
should follow for the adjustment of compensation.
• Set the attenuation coefficient of your Probe to x10, Switch on your instrument and go
to CH1 MENU, than F3 to change the Probe to 10X. Connect your Probe properly to
built-in 1kz 5V test signal output marked with PROBE COMP, Press AUTOSET to
continue.
• Compare the waveform displayed on your with these reference and make sure your
waveform is not overcompensated or under compensated.
Fig.7 Reference Waveforms
• Repeat this if needed. Adjust the Probe using supplied screw until you get a square
wave looked like reference waveform 2.
Fig.8 Adjust to compensate the Probe.
User’s Manual: OWON Portable Digital Storage Oscilloscope 14
www.owon.co.uk Email: [email protected] Tel: +44 8450 508168 V5.02
3.5 Set correct Attenuation Coefficient for Probes
CAUSTION: The default factory attenuation coefficient set on the instrument for
both Channel 1 and Channel 2 are 10X.
The standard Probes supplied support 1X and 10X. Probes support 100X or 1000x are
available to purchase for an extra cost.
Choosing different attenuation coefficients changes the vertical scale factor of the
display. It’s always important to make sure attenuation coefficient on both the
Channel of the scope and the Probe connected to that channel are matched with the
same settings.
Switch on your Scope and Select the CH1 MENU OR CH2 MENU, under Probe
section, Press F3 to choose Attenuation Coefficient you want to use. Once it is done,
the scope would remember the setting until it is changed.
Check your Probe before connecting to Input Channel and make sure it is set to the
same setting of that Channel on the Oscilloscope. Fig 9 shows you where to change
the settings on your Probe.
Fig.9 Attenuation Switch
CAUSTION: The Probe is limited to work with up to 5mhz signal when using
x1, to use the full bandwidth of the scope, You should always set to use x10.

on Fig.10. Please take caution use the Probe.
Fig.10 Finger Guard
Warning:
• Always keep your finger behind the safety ring while any tests are in operation to
avoid electric shock.
• Do NOT touch any metal Part of the Probe including the tip during any
operations or when it is connected to any power source.
• Always connect the Ground terminal of the Probe to the earth before taking any
measurements.
3.7 Do Self-calibration
All our Oscilloscopes have a built-in function called “Do Self Calibration”. This is to set the
Oscilloscope to its best possible condition to help users for a quick and accurate measurement.
You can do this at any time if you wish to, please make sure to run this function whenever the change
of ambient temperature is 5 or over, this is to ensure you always get the best possible measurements
from your instrument.
Before carrying out a self –calibration, please disconnect all Probes or inputs from the
Oscilloscope. Press “UTILITY” then button F3 which is next to “Do Self Cal”. You will
see a Pop-up yellow box to reminder you to remove any Probes and other attachments to
the inputs of Oscilloscope, once they are all done, Press F3 again. The Oscilloscope would
start its self-calibration route and the yellow box remains to show you the progress till the
process is done.
Warning: DO NOT TOUCH OR CONNECT ANYTHING TO THE INPUTS WHEN
IT IS DOING SELF-CALIBRATION. IT COULD CAUSE POTENTIAL DAMAGE TO
THE INSTRUMENT AS WELL AS THE OPERATOR.

Window options in FFT
There are four options for selecting FFT Window. It is about resolution of frequency and
accuracy of magnitude. Depending on the measurements you are looking for and the
characteristic of your source signal, you can choose different options. Table 4-5 gives you
some basic knowledge on which option you want to choose.
Type Characteristics and use Window
Type
Rectangle
Have best resolution for frequencies measurement, but worst for
magnitude.
Recommend to use for:
• Measure transients or bursts where the signal levels before and after
the event are nearly equal.
• Equal-amplitude sine waves with frequencies that are very close
• Random noise within a broadband with a relatively slow varying
spectrum.
Hamming
Better for frequency measurement than Hanning, and good for
magnitude as well. Recommend to use:
• Measure sine, periodic and narrow banded random noise.
• Work well on transients or bursts where the signal levels before and
after the event are significantly different.
Hanning
Better resolution for measuring magnitude, but OK frequency
measurement. Recommend to use for:
• Measure sine, periodic and narrow banded random noise.
• Work on transients or bursts where the signal levels before and after
the event are significantly different.
Blackman
Best for measuring magnitude, but worst for frequency. Recommend to
use for:
• Measure predominantly single frequency waveforms and look for
higher order harmonics.
Here are examples for measuring sine wave with a frequency of 1Khz under the selection of

four different window for FFT.
Fig.21 Rectangle window Fig.22 Hamming window
Fig.23 Hanning window Fig.24 Blackman window
Notes for using FFT:
• Use Zoom function for FFT waveform if it is necessary.
• Use dBVrms for details of multiple frequencies measurement
• Use Linear rms to compare frequencies.
• DC or offset affect magnitude of waveform, Use AC mode on source signal instead of DC.
• Set acquisition mode to “AVERAGE” to reduce effect of random noise
What is Nyquist frequency?
The Nyquist frequency is half the sampling frequency of Digital Oscilloscope. It is sometimes known as
the folding frequency of a sampling of DSO. The aliasing can be avoided if the Nyquist frequency is
greater than the maximum frequency of the signal being sampled.

4.3 Use Trigger Controls
You are already familiar with trigger controls after reading Chapter 3. These are TRIG
LEVEL, SET TO 50%, FORCE TRIG, SET TO ZERO and TRIG MENU. We now are
going through each of these controls in details and use them for test.
Your oscilloscope can collect data and plot waveform simultaneously. The waveform would
not be stable and meaningful unless a proper trigger is set up. Very often in the tests, users
are interested in events/data after incoming signal has been triggered. Once your
Oscilloscope detects a trigger, it starts to acquire data and plot waveform from this particular
point, it is what we call- trigger point.
4.3.1 Trigger Menu for PDS5022S、、、、PDS6042S、、、、PDS6062S、、、、PDS6062T
There are two types of trigger for models mentioned above-Edge Trigger and Video
Trigger. Each type has its function menu for users to set them up. Press Trigger Menu to
active your trigger settings. Press F1 next to the display to switch trigger from one type to
another.
Use Edge Trigger
Edge trigger is one of the common triggers you would find on Oscilloscope. The Trigger
happens when the input signal going over a threshold of Voltage on the set direction. You
can choose Rising edge or Falling edge for how you want the trigger to start. Here is the
Edge Trigger Menu shown as Fig. 30.

5.2 Example: Working out the Gain of a Amplifier in a Metering Circuit
The purpose of this example is to work out the Gain of an Amplifier in a Metering Circuit. First we
use Oscilloscope to measure the amplitude of input signal and output signal from the circuit, then
to work out the Gain by using given formulas.
Step 1
Go to Both CH1 MENU and CH2 MENU and then their Probe menu to set attenuation coefficient
as 10X, turn the switch on the Probes to 10X as well.

5.3 Example: Capturing a Single pulse
It’s quite easy to use Digital Oscilloscope to capture non-periodic signal, such as a pulse
and burr etc. But the common problem is how to set up a trigger if you have no knowledge
of the signal? With various functions supported by our Oscilloscope, user can solve this
problem by taking an easy approach. First to run your test using auto trigger to find out the
closest trigger level and trigger type, this helps user to make few small adjustments to
achieve a proper trigger level and mode. Here is how we achieve this.
Step 1
Go to Both CH1 MENU and CH2 MENU and then their Probe menu to set attenuation coefficient
as 10X, turn the switch on the Probes to 10X as well.
Step 2
Connect the Probe1 through Channel 1 to its signal source and adjust VOLTS/DIV and SEC/DIV
controls to set up a proper range of Voltage and time base for the signal.
Step 3
Press ACQUIRE to use ACQUIRE MODE, then F2 to select Peak Detect.
Step 4
Press TRIG MENU to activate Trigger MODE, F1 to select Single, F2 to choose CH1
as a source, F3 to select Edge for the type, F4 to set Rising for the slope and finally adjust
the trigger level to the roughly 50% of the incoming signal.
Step 5
Check the Trigger State Indicator on the top of the screen, if it is not Ready, push down
RUN/STOP and start Acquire, wait for trigger to happen, if not adjust the level repeat
Step 5 again until a sampled signal captured and display on the screen.
By using this approach, a random pulse can be easily captured. For instance, if we want to
find a burst burr of high amplitude, set the trigger level to a slightly higher value of the
average signal level, Press RUN/STOP and wait a trigger, once it happens, a triggered
waveform would be captured. User also can change the Horizontal triggering position to
have more details of how and when the burr happens. (Fig.66 gives you more details).

5.4 Example: Noise analysis and reduction
Noise is very common inside most of the electronic signal. To find out what’s inside the
noise and reduce the level of noise is very important function our oscilloscope is capable
to offer.
Noise Analysis
The level of noise sometime indicates a failure of electronic circuit. The Peak Detect
functions acts an important role to help you to find out the details of these noise. Here is
how we do it:
Step 1
Apply Square waveform to CH1 as source signal, Press ACQUIRE button to activate
ACQU MODE menu.
Step 2
Press F2 to select Peak Detect function. The signal displayed on the screen containing
some noise, by turning on Peak Detect function and changing time base to slow down the
incoming signal, any peaks or burr would be detected by the function. (See Fig.67).
Fig.67 Signal with Noises
User’s Manual: OWON Portable Digital Storage Oscilloscope 59
www.owon.co.uk Email: [email protected] Tel: +44 8450 508168 V5.02
Reduce the effect of noise from your signal
When focusing on signal itself, the important thing is to reduce the noise level as lower as
possible, this would enable user to have more details about the signal. The Average
function offered by our Oscilloscope can help you to achieve this.
Here are the steps for how to enable Average function.
Step 1
Apply square waveform to CH1 as a source signal. Press ACQUIRE button to bring up
ACQU MODE menu.
Step 2
Press F3 select Average, Press F4 to select number of data points for average. Available
choices of number are 16, 32, 64 and 128. The higher the number, the better result user
will get.
User would see a much reduced random noise level and make it easy to see more details of
the signal itself. As it is in Fig. 68, after applying Average, user can easily indentify the
burrs on the rising and falling edges of some part of the signal (see Fig.68).

5.5 Example: Examine the Phase shift between two related signals
X-Y mode is a very useful when examining the Phase shift of two related signals. This
example takes you step by step to check out the phase change of the signal after it passes a
specified circuit. Input signal to the circuit and output signal from circuit are used as
source signals.
Step 1
Set up attenuation coefficient to 10X through Probe menu for both CH1 and CH2. Switch
Probes to 10X. For source signals, CH1 takes in input signal to the circuit and CH2 takes
in output signal from circuit.
Step 2
Press AUTOSET, Adjust the VOLTS/DIV for both CH1 and CH2 to the same amplitude
level to get an ellipse.
Step 2
Press DISPLAY to activate DISP SET menu, then F3 to select XY mode. Now the
waveform is displayed as Lissajou’s curve, adjust VOLTS/DIV and VERTICAL
POSITION to get the best possible display, work out the phase shift as in Fig. 69
Fig.69 Lissajous Graph
Sine (q) =A/B or C/D
Where q is the angle of phase shift, A, B, C, and D as them in Fig .69.
The angle of phase shift q =± arcsine (A/B) or ± arcsine (C/D).
The signal must be
centered and are kept in
the horizontal direction.

6. Troubleshooting
• Oscilloscope is powered on but no Display.
Check power socket/power are connected and make sure all switches are on. If the
problem persists, please contact our Customer Support & Service Team.
• Oscilloscope is powered on, the backlight is on, but can’t see anything as screen is too
bright or dark. (Model PDS5022s, PDS6042s and PDS6062s)
Brightness level of display is wrong. Please adjust the brightness control under the display
to the right level.
• Oscilloscope is powered on and application is running, only two flat lines, but no
waveform displayed.
First to check Probes contact to make sure the connections are OK and the signals are
coming through BNC connector. Second to check the source signal is connected properly
to Probes.
• The Voltage reading is 10 times or 1/10 of the actual value.
Look at the attenuation coefficient for the input channel and the attenuation ration of the
probe, to make sure they are match.
• There is a wave form displayed on the screen, but jumping up and down.
Check your trigger settings to make sure you are using the right source and right choice of
settings.
• Waveform stops and no change whatsoever when pressing RUN/STOP.
Check the Polarity settings in TRIG MODE menu and make sure the trigger level is
within the range of your input signal. Or Press AUTOSET for a quick check.
• The displaying of waveform seems getting slow after increasing AVERAGE value in
ACQU MODE or a longer time is set in the DISP MODE.
It’s normal as the Oscilloscope is working hard on many more data points you’ve included.
