Pollution Degre e Description

A measure of the contaminants that could occur in the environment around and within a product. Typically the internal
environment inside a p roduct is considered to be the same a s 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 clean 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 conductive 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 corresponding
oscilloscope channel, allowing the
oscilloscope to optimize the signal input
path. This provides AC compensation
across the frequency band.

Installation

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 (MSO4000B Series

only)
The P6616 probe provides 16 channels

of digital (on or off state) information.

For more information on the many probes available for use with MSO4000B and DPO4000B Series oscilloscopes, visit the

Compensating a TPP0500B or TPP1000 Passive Voltage Probe

The MSO4000B and DPO4000B can automatically compensate 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 specifi c 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.

Application Module Free Trial

A 30-day free trial is available for all application module 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 c ontinue 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, use multipurpose knob a to select

Config, and push About on the lower menu.

Installing an Application Module

CAUTION. To avoid damage to the oscilloscope or application module, observe ESD (electrostatic discharge) precautions.

(See page 11, Powering on the Oscilloscope.)

Turn off the oscilloscope power while removing or adding an application module.

(See page 12, Powering off the Oscilloscope.)

Installation

Optional application module packages extend the capability of your oscilloscope.

You can physically install up to four application modules at one time. Application modules go into the two slots with windows
in the upper ri
slots, install the module with the label facing away from you.

Each module has a license, which you can optionally transfer between your application modules and oscilloscope. You can
keep each license in the module, which w ill 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 f
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 m odules in the oscilloscope. Turn on the power.

2. Push Utility on the front panel. If needed, push Utility Page on the lower menu, and turn multipurpose knob a to select

Config. Push Manage modules & Options on the lower menu and the appropriate side menu buttons to transfer

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 (or immediately after running the Self Test routine on the instrument). Failure to do
so may result in the instrument not meeting warranted performance levels at those volts/div settings.

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. 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.

When and Why to Turn On MagniVu

For MSO4000B Series only, MagniVu allows you to have higher resolution to accurately determine edge placement. This

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 a cquisition is complete and the holdoff time has expired.

Untrigg

ered display

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 waveform 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 wav eform 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 Force Trig on the front panel.

The part of the record that occurs before the trigger is the pretrigger portion. The part that occurs after the trigger is the
posttrigger portion. Pretrigger data can help you troubleshoot. For example, to find the cause of an unwanted glitch in
your test circuit, you can trigger on the glitch and make the pretrigger period large enough to capture data before the
glitch. By analyzing w hat happens before the glitch, you may uncover information that helps you find the source of the
glitch. Alternatively, to see what is happening in your system because of the trigger event, make the posttrigger period
large enough to capture data after the trigger.
