Getting Started with the MSO/DPO2000, MSO/DPO3000, and MSO/DPO4000 Series Oscilloscopes
Getting Started with the MSO/DPO2000, MSO/DPO3000, and
MSO/DPO4000 Series Oscilloscopes
These instructions quickly guide you through basic controls and capabilities of the MSO/DPO2000, MSO/DPO3000, and
MSO/DPO4000 series oscilloscopes. To learn about more advanced capabilities, read the corresponding oscilloscope user manual.
NOTE. The MSO4000 and DPO4000 series oscilloscopes described in this manual require firmware version 2.XX or higher. To
check the firmware version number, push the Utility front panel button and view the Version. If your oscilloscope uses firmware
version 1.XX, download new firmware and update your oscilloscope using procedures described in your oscilloscope user manual.
NOTE. This manual is part of the Tektronix 020-2924-XX Demo 2 board kit. The kit includes a Demo 2 board, this manual, and
a USB cable.
Demo 2 Board Instruction Manual 1

Getting Started with the MSO/DPO2000, MSO/DPO3000, and MSO/DPO4000 Series Oscilloscopes
Demo I: Acquiring a Signal
1. Connect the host side of the USB cable to
the USB port on the lower-left corner of the
oscilloscope front panel — or to either of
the two USB host ports on the rear panel
of some models.
2. Connect the other end of the cable to the
device port on the Demo 2 board.
3. The POWER LED will light on the Demo 2
board.

4. Connect a probe to channel 1, such as
the P2221 with the MSO/DPO2000 or
the P6139A with the MSO/DPO3000 or
MSO/DPO4000. Then connect the ground
lead of the probe to a point labeled GND
on the Demo 2 board. Attach the probe
tip to the square pin on the Demo 2 board
labeled CNT CLK.
NOTE. CNT CLK is a clock used for a
synchronous counter.

Getting Started with the MSO/DPO2000, MSO/DPO3000, and MSO/DPO4000 Series Oscilloscopes
5. Push Default Setup to put the oscilloscope
back to a known starting point. In general,
this is a good thing to do any time you are
starting a new task.
6. Push Autoset.
Autoset automatically adjusts the
horizontal, vertical, and trigger parameters
to give a usable display of the signal of
interest. You should now see several
cycles of the clock signal.

Getting Started with the MSO/DPO2000, MSO/DPO3000, and MSO/DPO4000 Series Oscilloscopes
Demo II: Using Vertical Controls
1. Turn the front-panel channel 1 Vertical
Scale knob in both directions and observe
how the display changes. Also, notice the
channel 1 readout on the lower left of the
display shows the current volts/div setting.
Set the Vertical Scale to 1 V/div.
2. Turn the front-panel channel 1 Vertical
Position knob in both directions and
observe how the display changes. Position
the waveform in the center of the display.

3. Push the front-panel channel 2button to
turn on channel 2. Push it again to turn off
channel 2.

Demo III: Using Horizontal Controls
1. Turn the front-panel Horizontal Scale
knob in both directions and observe the
display. Also, notice the horizontal readout
indicating the current time/div setting. Set
the Horizontal Scale to 200 ns/div.
2. Turn the front-panel Horizontal Position
knob both directions and observe the
display. Notice that this affects the trigger
position icon (the big T on an orange
background). Return the trigger position
icon to center screen.
3. Take a look at the graphic shown above
the graticule. The long yellow bar
represents the overall acquisition while
the gray brackets indicate the portion of
theacquisitionyouarelookingatonthe
screen.

Getting Started with the MSO/DPO2000, MSO/DPO3000, and MSO/DPO4000 Series Oscilloscopes
Demo IV: Using Run/Stop Controls
1. Push the Run/Stop button. This stops
acquisitions with the last acquired
waveform on the display.
2. Push Single to have the oscilloscope
acquire a single waveform and then stop.
3. Push the Run/Stop button again to restart
acquisitions.
Demo V: Using Trigger Controls
1. Turn the Trigger Level knob in both
directions and observe the display. Turn it
far enough to move the trigger level off the
waveform.
Demo 2 Board Instruction Manual 9

Getting Started with the MSO/DPO2000, MSO/DPO3000, and MSO/DPO4000 Series Oscilloscopes
Notice that the oscilloscope loses its stable
trigger and the waveform now appears to
randomly scroll by.
2. Push the Force Trig button once and
notice that the oscilloscope shows a single
acquisition for a moment. This gives you
an idea of what the waveform looks like
so you can set an appropriate and stable
trigger.

3. On the MSO/DPO4000, push the Set to
50% button. This automatically sets the
trigger level to the midpoint of the signal
for a stable trigger.
On the MSO/DPO2000 and
MSO/DPO3000, push the Level
knob. This will set the trigger level to the
midpoint.

Demo VI: Using Cursors
1. Push the front-panel Cursors button.
Two vertical bar cursors now appear in
the graphic above the graticule. The
corresponding cursor readout displays
the time of each cursor relative to the
trigger and amplitude along with the deltas
between the cursors.
2. Using the multipurpose aand bknobs,
bring the cursors on screen.
12 Demo 2 Board Instruction Manual

Getting Started with the MSO/DPO2000, MSO/DPO3000, and MSO/DPO4000 Series Oscilloscopes
Hint: To move the cursors faster, turn off
fine mode by pushing the Fine button,
if lit, on the front panel between the two
multipurpose knobs.
3. Place one cursor at the midpoint of the
first falling edge. Place the other cursor at
the midpoint of the second falling edge to
measure the signal’s period. The cursor
readout should show a difference between
the cursors of approximately 800 ns.
Hint: To move the cursors more slowly, turn
the fine mode back on by pushing the Fine
button, if unlit, on the front panel between
the two multipurpose knobs.
