Cleaning
Inspect the oscilloscope and probes as often as operating conditions require. To clean the exterior surface, perform the
following steps:
1. Remove loose dust on the outside of the oscilloscope and probes with a lint-free cloth. Use care to avoid scratching
the display.
2. Use a soft cloth dampened with water to clean the oscilloscope. Use an aqueous solution of 75% isopropyl alcohol
for more efficient cleaning.
CAUTION. Avoid getting moisture inside the unit during external cleaning. Use only enough cleaning solution to dampen
the cloth or swab.
CAUTION. To avoid damage to the surface of the oscilloscope or probes, do not use any abrasive or chemical cleaning
agents.
Connecting Probes
The oscilloscope supports probes with the following:
1. Tektronix Versatile Probe Interface
(TekVPI)
These probes support two-way
communication with the oscilloscope
through on-screen menus and remotely
through programmable support. The
remote control is useful in applications
like ATE where you want the system to
preset probe parameters.
2. Tektronix Versatile Probe Interface
(TekVPI) for Passive Probes
These probes build upon the functionality
of the TekVPI interface. Each probe
is matched with its corresponding
oscilloscope channel, allowing the
oscilloscope to optimize the signal input
path. This provides AC compensation
across the frequency band.

Compensating a TPP0250, TPP0500B or TPP1000 Passive Voltage Probe
The MDO3000 Series oscilloscopes can automatically compensate T PP0250, TPP0500B and TPP1000 probes. This
eliminates the need for manual probe compensation, as is typically performed with other probes.
Each compensation generates values for a specific probe and channel combination. If you want to use the probe on another
channel and desire to compensate the new probe-channel pair, you must run a new set of compensation steps for that new
ination.

When compensating TPP0250/TPP0500B/TPP1000 probes on the MDO3000 S eries oscilloscopes:
Each compensation generates values for a specific probe and channel combination. If you want to use the probe on
another channel and desire to compensate the new probe-channel pair, you must run a new set of compensation steps.
Installation
Each channel can store compensation values for 10 individual probes. If you try to compensate an 11th p robe on a
channel, the oscilloscope will delete the values for the least recently used probe and add the values for the new probe.
The oscilloscope w
ill assign default compensation values to a TPP0250, TPP0500B or TPP1000 probe connected to
the Aux In channel.
NOTE. A factory calibration will delete all stored compensation values
NOTE. A probe com
pensation failure is most likely due to intermittent connection of the probe tip or ground connection
during the probe compensation operation. If a failure occurs, the oscilloscope will re-use the old probe compensation values,
if they existed prior to the failed probe compensation operation.
Compensating a non-TPP0250, non-TPP0500B or non-TPP1000 Passive
Voltage Probe
Whenever you attach a passive voltage probe for the first time to any input channel, compensate the probe to match it to
the corresponding oscilloscope input channel.
If you are interested in using the automatic probe compensation procedure described above for the TPP0250, TPP0500
and TPP1000 probes (See page 11, Compensating a TPP0250, TPP0500B or TPP1000 Passive Voltage Probe.). On a
non-TPP0250/TPP0500B/TPP1000 Tektronix passive probe, check the instruction manual for your probe to see if it qualifies.
Otherwise, to properly compensate your passive probe:
1. Follow the steps for the functional
check. (See page 10, FunctionalCheck.)

Application Module Free Trial
A 30-day free trial is available for all application m odule licenses not installed in your oscilloscope. The trial period begins
when you power on the oscilloscope for the first time.
After 30 days, you must purchase the module if you want to continue using the application. To see the date when your
free trial period expires, push Utility on the front panel, push Utility Page on the lower menu, turn the Multipurpose a
knob to select Config, and push About on the lower menu.
Installing an Application M odule
CAUTION. To avoid damage to the oscilloscope or application module, observe ESD (electrostatic discharge) precautions.
(See page 9, Powering on the Oscilloscope.)
Turn off the oscilloscope power while removing or adding an application module.
(See page 10, Powering off the Oscilloscope.)
14MDO3000 Series Oscilloscopes User Manual
Installation
Optional application module packages extend the capability of your oscilloscope.
You can physically install up to two application modules at one time. Application modules can go into the slots with a window
in the upper right corner of the front panel. One additional slot is directly behind the one that you can see. To use the hidden
slot, install the module with the label facing away from y ou.
Some of the modules have licenses that allow you to transfer the license between your application modules and the
oscilloscope. You can keep each license in the module, which will allow you to move the module from one instrument to
another. Alternatively, you can move the license from the module to the oscilloscope. This approach will allow you to store
the module separately from the oscilloscope for safe keeping. This approach will also allow you to use more than two
applications on your oscilloscope simultaneously. To transfer a license from a module to your oscilloscope or from your
oscilloscope to a module:
1. Turn off the power to the oscilloscope. Insert the application modules into the oscilloscope. Turn on the power.
2. Push Utility on the front panel. If needed, push Utility Page on the lower menu and turn the Multipurpose a knob to
select Config. Push Manage Modules and Options on the lower menu, and then push License Type on the side menu
until “Modules” is selected. The licenses contained in the oscilloscope will be listed in the side menu. Push the button
next to the appropriate license to transfer. You may transfer up to two licenses at one time.
3. After you turn off the power to the oscilloscope, you can remove the physical application module from the oscilloscope.
Refer to the MDO3000 Series Oscilloscopes Application Module Installation Manual that came with your application module
for instructions on installing and testing an application module.
NOTE. If you transfer a license from a module to an oscilloscope, the module will not work on another oscilloscope until
you transfer the license back from the oscilloscope to the module. Consider putting the physical module in an envelope
or other storage with a label recording the date, module name, model and serial number of the oscilloscope which holds
the license. This will help prevent confusion later if someone finds the module, installs it in some other oscilloscope,
and wonders why it does not work.

Signal Path Compensation
Signal Path Compensation (SPC) corrects for DC inaccuracies caused by temperature variations and/or long-term drift.
Run the compensation whenever the ambient temperature has changed by more than 10 °C (18 °F) or once a week
if you use vertical settings of 5 mV/division or less. Failure to do so may result in the instrument not meeting warranted
performance levels at those volts/div settings.
Signal Path Compensation for Time and Frequency Domains
To compensate the signal path:
1. Warm up the oscilloscope for at least
20 minutes. Remove all input signals
(probes and cables) from channel inputs.
Input signals with AC components adversely
affect SPC.

7. Push Delay on th
On when you want to delay the acquisition
relative to the trigger event.
With Delay set to On, turn the Horizontal Position knob counterclockwise to increase the delay. The trigger point will move
to the left and ultimately outside of the acquired waveform. Then you can adjust the Horizontal Scale knob to acquire more
detail around the area of interest at the center of the screen.
When this delay is on, the trigger point separates from the horizontal expansion point. T he horizontal expansion point
stays at the center of the screen. The trigger point can move off the screen. When this happens, the trigger marker turns
to point in the direction of the trigger point.
Use the delay feature when you want to acquire waveform detail that is separated from the trigger event by a significant
interval of time. For example, you can trigger on a sync pulse that occurs once every 10 ms and then look at high-speed
signal characteristics that occur 6 ms after the sync pulse.
When the delay feature is s et to Off, the expansion point is tied to the trigger point so that scale changes are centered
around the trigger point.
