Getting Started with the Tektronix 4000 Series
The following instructions will quickly guide you through basic controls and capabilities of the DPO4000 and MSO4000 Series
oscilloscopes. Learn about more advanced capabilities by reading the Tektronix 4000 Series User Manual (071-2121-XX).
NOTE. This manual works with DPO4000 and MSO4000 Series oscilloscopes with firmware version 2.XX. 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 020-2694-XX demo kit. The kit includes a demo board, this manual, and a USB cable.

Getting Started with the Tektronix 4000 Series
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.
2. Connect the other end of the cable to
the device port on the demo board. (See
page 102, Operating the Demo Board.)
3. Confirm that the LED labeled USB POWER
is lit on the demo board.

4. Connect a P6139A probe to channel 1.
Then connect the ground lead of the
P6139A probe to a point labeled GND on
the demo board. Attach the probe tip to
the square pin on the demo board labeled
CNT CLK.
NOTE. CNT CLK is a clock used for a
synchronous counter.
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.

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.

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 20 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
the acquisition you are looking at on the
screen.

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.

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. Push the Set to 50% button. This
automatically sets the trigger level to the
midpoint of the signal for a stable trigger.

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.

Getting Started with the Tektronix 4000 Series
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 100 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.
