Brief Introduction to DSO4000 Series
DSO4000 Series oscilloscopes cover the bandwidths from 70MHz to 200MHz, and provide
the real-time and equivalent sample rates respectively up to 1GSa/s and 25GSa/s. In addition,
they have 7 inch color TFT LCD as well as WINDOWS-style interfaces and menus for easy
operation.
What’s more, the plenty menu information and the easy-to-operate buttons allow you to gain
information as much as possible in measurement; the multifunctional knobs and the powerful
shortcut keys help you save a lot of time in operation; theAutoset function lets you detect sine and
square waves automatically; the Probe Check Wizard guides you to adjust the probe
compensation and set the Probe option attenuation factor. By using the three methods the
oscilloscope provides (context-sensitive, hyperlinks, and an index), you may master all operations
on the device in quite a short time so as to greatly improve your efficiency in production and
development.

1.2 Functional Check
Follow the steps below to perform a quick functional check to your oscilloscope.
1.2.1 Power on the oscilloscope
Plug in the oscilloscope and press the ON/OFF button. Then push the “UTILITY ->F6 ->F6 ->
F6->DEFAULT”button. The default Probe option attenuation setting is 10X.
1.2.2 Connect the oscilloscope
Set the switch on the probe to 10X and connect the probe to Channel 1 on the oscilloscope. First,

DSO4000 Series Digital Storage Oscilloscope 4
align the slot in the probe connector with the protuberance on the CH1 BNC and push to connect;
then, turn to right to lock the probe in place; after that, connect the probe tip and reference lead to
the PROBE COMP connectors. There is a mark on the panel: Probe COMP ~5V@1KHz.
1.2.3 Observe the waveform
Press the AUTOSET button and you should see within a few seconds a square wave of about 5V
peak-to-peak at 1kHz in the display. Press the CH1 MENU button twice to remove Channel 1.
Push the CH2 MENU button and repeat Step 2 and Step 3 to observe Channel 2.
1.3 Probe Examination
1.3.1 Safety
When using the probe, keep your fingers behind the guard on the probe body to avoid electric
shock. Do not touch metallic portions of the probe head while it is connected to a voltage source.
Connect the probe to the oscilloscope and connect the ground terminal to ground before you start
any measurements.
CH1: to connect with the probe
PROBE COMP

DSO4000 Series Digital Storage Oscilloscope 5
1.3.2 Use of Probe Check Wizard
Every time you connect a probe to an input channel, you should use the probe check wizard to
verify that this probe is operating correctly.
Use the vertical menu (for example, push the CH1 MENU button) to set the Probe option
attenuation factor.
1.3.3 Manual Probe Compensation
Upon the first connection of a probe and an input channel, you should manually perform this
adjustment to match the probe to the input channel. Uncompensated or miscompensated probes
may lead to errors or faults in measurement. To adjust the probe compensation, follow the steps
below.
1. Set the Probe option attenuation in the channel menu to 10X. Set the switch on the probe to
10X and connect the probe to Channel 1 on the oscilloscope. If you use the probe hook-tip,
ensure it is firmly inserted onto the probe. Attach the probe tip to the PROBE COMP
~5V@1KHz connector and the reference lead to the PROBE COMP Ground connector.
Display the channel and then press theAUTOSET button.
2. Check the shape of the displayed waveform.
3. If necessary, use a nonmetallic screwdriver to adjust the variable capacity of your probe until
the shape of the waveform turns to be the same as the above figure. Repeat this step as
necessary. See the figure below for the way of adjustment.
Compensated correctly
Overcompensated
Undercompensated

DSO4000 Series Digital Storage Oscilloscope 6
1.3.4 Probe Attenuation Setting
Probes are of various attenuation factors which affect the vertical scale of the signal. The Probe
Check function is used to verify if the Probe attenuation option matches the attenuation of the
probe.
As an alternative method to Probe Check, you can push a vertical menu button (such as the CH 1
MENU button) and select the Probe option that matches the attenuation factor of your probe.
Make sure that the Attenuation switch on the probe matches the Probe option in the oscilloscope.
Switch settings are 1X and 10X.
When the Attenuation switch is set to 1X, the probe limits the bandwidth of the oscilloscope to
6MHz. To use the full bandwidth of the oscilloscope, be sure to set the switch to 10X.
1.4 Self Calibration
The self calibration routine helps optimize the oscilloscope signal path for maximum measurement
accuracy. You can run the routine at any time but should always run it if the ambient temperature
changes by 5℃or more. For a more accurate calibration, please power on the oscilloscope and
wait for 20 minutes until it has adequately warmed up.
To compensate the signal path, disconnect any probes or cables from the front-panel input
connectors. Then, push the UTILITY button, select the Do Self Cal option and follow the directions
on the screen.

See the figure below to find the seven signals connectors and a pair of metal electrodes at the
bottom of the oscilloscope panel.
1. GEN OUT: Waveform Signal Output.
F0: Hide/Show button. Push it to hide the menu options on the right side of the
screen and give a full screen display of waveforms. Push it again to show the menu
options.

corresponding menu options on the screen in different menu modes. For example, in
the UTILITY menu, F1-F5 respectively correspond to ‘System Info’–‘Advance’.
F6: This functional button is mainly used to turn pages and confirm a selection, such
as ‘next page’, ‘previous page’, and ‘press F6 to confirm’appearing when you push
Self Calibration option.
V0: Multi-functional knob. Under different menu options, it supports selecting menu
options (MEASURE), moving cursors and levels (Slope Trigger).
Press this knob to reset data (trigger holdoff, overtime of the overtime trigger and

6. Probe Compensation: Voltage probe compensation output and ground, used to electrically
match the probe to the oscilloscope input circuit. The probe compensation ground and BNC
shields connect to earth ground and are considered to be ground terminals. To avoid
damages, do not connect a voltage source to any of these ground terminals.
2.4 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.
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.
2.5 Default setups
The default setups represent some option parameters that are set before the oscilloscope leaves
factory for normal operations.
When you push “UTILITY->Default”button, the oscilloscope will display the CH1 waveform and
remove all the others. The table below gives the options, buttons and controls that change settings
at default setup.

2.6 Horizontal System
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 change 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. W indicates ‘Window Time Base’. The oscilloscope also has an arrow icon at
the top of the graticule to indicate the horizontal position.
