Pollution Degree Description
A measure of the contaminants that could occur in the environment around and within a product. Typically the internal
environment inside a product is considered to be the same as the external. Products should be used only in the environment
for which they are rated.
Pollution Degree 1. No pollution or only dry, nonconductive pollution occurs. Products in this category are generally
encapsulated, hermetically sealed, or located in c lean rooms.
Pollution Degree 2. Normally only dry, nonconductive pollution occurs. Occasionally a temporary conductivity that is
caused by condensation must be expected. This location is a typical office/home environment. Temporary condensation
occurs only when the product is out of service.
Pollution Degree 3. Conductive pollution, or dry, nonconductive pollution that becomes conductive due to condensation.
These are sheltered locations where neither temperature nor humidity is controlled. The area is protected from direct
sunshine, rain, or direct wind.
Pollution Degree 4. Pollution that generates persistent conductivity through c onductive dust, rain, or snow. Typical
outdoor locations.
Pollution Degree
Pollution Degree 2 (as defined in IEC 61010-1). Note: Rated for indoor use only.

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 c orresponding
oscilloscope channel, allowing the
oscilloscope to optimize the signal input
path. This provides AC compensation
across the frequency band.
3. TPA-BNC Adapter
The TPA-BNC Adapter allows you to
use TEKPROBE II probe capabilities,
such as providing probe power, and
passing scaling and unit information to
the oscilloscope.
4. BNC Interfaces
Some of these use TEKPROBE
capabilities to pass the waveform signal
and scaling to the oscilloscope. Some
only pass the signal and there is no other
communication.
5. Logic Probe Interface
The P6616 probe provides 16 channels
of digital (on or off state) information.
6. The TPA-N-VPI Adapter allows you to
use TekVPI probes in the RF input.
For more information on the many probes available for use with MDO4000 Series oscilloscopes, refer to www.tektronix.com.

Compensating a TPP0500 or TPP1000 Passive Voltage Probe
The MDO4000 Series oscilloscopes can automatically compensate TPP0500 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
combination.

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 Domain s
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.

Signal Path Compensation for Frequency Domain Only
The signal path compensation (SPC) described above runs on both the time and the frequency domain inputs. If you only
want to compensate the RF input, you can save time by running SPC only on the RF input and skipping the time domain
part. You can do this as follows:
1. As with the time and frequency calibration,
warm up the oscilloscope for at least
20 minutes. Remove all input signals
(probes and cables) from the RF input.
2. Push RF to bring up the Frequency Domain

Connecting Your Oscilloscope to a Computer
Connect your oscilloscope directly to a computer to let the PC analyze your data, collect screen images, or to control your
oscilloscope. (See page 163, Saving a Screen Image.) (See page 164, Saving and Recalling Waveform and Trace D ata.)
Three ways to connect your oscilloscope to a computer are through the VISA drivers, the e*Scope Web-enabled tools, and
a socket server. Use VISA to communicate with your oscilloscope from your computer through a software application,
such as Tektronix OpenChoice Desktop®. Use e*Scope to communicate with your oscilloscope through a Web browser,
such as Microsoft Internet Explorer.

Quick Tips
To position the waveform appropriately, Autoset may change the vertical position. Autoset always sets vertical offset
to0V.
If you use Autoset when no channels are displayed, the instrument turns on channel 1 and scales it.
If you use Autoset and the oscilloscope detects a video signal, the oscilloscope automatically sets the trigger type to
video and makes other adjustments to display a stable video signal.

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. The 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 set to Off, the expansion point is tied to the trigger point so that scale changes are centered
around the trigger point.

NOTE. The oscilloscope displays the decode traces and event tables for all buses with the MSB on the left and LSB
on the right.
For example, an RS-232 signal (after the start bit) might be high, high, high, low, high, low, low, and high. Since the RS-232
protocol uses high for zero and low for one, this value would be 0001 0110.

When and Why to Turn On MagniVu
Te ktronix MagniVu acquisition technology allows you to have higher timing resolution so that you can more accurately
determine edge placement and make more precise timing measurements on digital edges. Using MagniVu, you can see
up to 32 times more detail than you can using normal digital channel sampling.
The MagniVu record is acquired in parallel to the main digita l acquisition and is available at any time, running or stopped.
MagniVu provides an ultra high resolution view of your data sampled at a maximum resolution of 60.6 ps for 10,000 points
centered around the trigger.
NOTE. MagniVu centers itself around the trigger point. If you turn MagniVu on while using a large record length and you are
looking somewhere other than the trigger point, then the digital signal may be off screen. In most of these cases, you can find
the digital record by looking for the digital signal in the upper overview and panning accordingly.
NOTE. You should turn on MagniVu when light gray shading is displayed to indicate the uncertainty of the edge position. If
the shading is not displayed, you do not need to use MagniVu. (See page 108, Viewing Digital Channels.)

Resolution Bandwidth
The resolution bandwidth (RBW) determines the level to which the oscilloscope can resolve individual frequencies in
the frequency domain. For example, i f the test signal contains two carriers separated by 1 kHz, you will not be able to
discriminate between them unless the RBW is less than 1 kHz.
The views below both show the same signal. The difference between them is their RBW.
Lower (narrower) RBWs take longer to process,
but have finer frequency resolution and a lower
noise floor.
Higher (wider) RBWs take less time to process, but have less frequency re solution
and a higher noise floor.

Trigger Setup
Trigger Setup
This section contains concepts and procedures for setting up the oscilloscope to trigger on your signal.
Triggering Concepts
Trigger Event
The trigger event establishes the time-reference point in the waveform record. All waveform record data is located in time
with respect to that point. The instrument continuously acquires and retains enough sample points to fill the pretrigger portion
of the waveform record. That is the part of the waveform that is displayed before, or to the left of, the triggering event on
screen. When a trigger event occurs, the instrument starts acquiring samples to build the posttrigger portion of the waveform
record, that is, the part displayed after or to the right of the trigger event. After a trigger is recognized, the instrument will not
accept another trigger until the acquisition is complete and the holdoff time has expired.
Untrigg
ered display
Trigger
ed display
Trigger Modes
The trigger mode determines how the instrument behaves in the absence of a trigger event:
Normal trigger mode enables the instrument to acquire a w aveform only when it is triggered. If no trigger occurs, the last
waveform record acquired remains on the display. If no last waveform exists, no waveform is displayed.
Auto trigger mode enables the instrument to acquire a waveform even if a trigger does not occur. Auto mode uses a
timer that starts when the acquisition is started, and the pretrigger information is obtained. If a trigger event is not
detected before the timer times out, the instrument forces a trigger. The length of time it waits for a trigger event
depends on the time base setting.
Auto mode, when forcing triggers in the absence of valid triggering events, does not synchronize the waveform on the
display. The waveform will appear to roll across the screen. If valid triggers occur, the display will become stable.
You can also force the instrument to trigger by pushing the front-panel Force Trig button.
