xvi AFG31000 Series Arbitrary Function Generator User's Manual
Do not disable the power cord grounding connection.
Power disconnect. The power cord disconnects the product from the power source. See
instructions for the location. Do not position the equipment so that it is difficult to operate the power
cord; it must remain accessible to the user at all times to allow for quick disconnection if needed.
Connect and disconnect properly. Do not connect or disconnect instruments while they are
connected to a voltage source.
Use only connectors and adapters supplied with the product, or indicated by Tektronix to be suitable
for the product.
Observe all terminal ratings. To avoid fire or shock hazard, observe all ratings and markings on the
product. Consult the product manual for further ratings information before making connections to the
product. Do not exceed the Measurement Category (CAT) rating and voltage or current rating of the
lowest rated individual component.
Do not apply a potential to any terminal, including the common terminal, that exceeds the maximum
rating of that terminal.
Do not float the common terminal above the rated voltage for that terminal.
Do not operate without covers. Do not operate this product with covers or panels removed, or with
the case open. Hazardous voltage exposure is possible.
Avoid exposed circuitry. Do not touch exposed connections and components when power is
present.
Do not operate with suspected failures. If you suspect that there is damage to this product, have it
inspected by qualified service personnel.
Disable the product if it is damaged. Do not use the product if it is damaged or operates incorrectly. If
in doubt about safety of the product, turn it off and disconnect the power cord. Clearly mark the
product to prevent its further operation.
Examine the exterior of the product before you use it. Look for cracks or missing pieces.
Use only specified replacement parts.
Wear eye protection. Wear eye protection if exposure to high-intensity rays or laser radiation exists.
Do not operate in wet/damp conditions. Be aware that condensation may occur if a unit is moved
from a cold to a warm environment.
Do not operate in an explosive atmosphere.
Provide proper ventilation. Refer to the installation instructions in the manual for details on
installing the product so it has proper ventilation.
Slots and openings are provided for ventilation and should never be covered or otherwise obstructed.
Do not push objects into any of the openings.
Provide a safe working environment. Always place the product in a location convenient for viewing
the display and indicators.

Important safety information
AFG31000 Series Arbitrary Function Generator User's Manual xvii

This section lists the EMC (electromagnetic compliance), safety, and environmental standards with
which the instrument complies.
EMC compliance
EC Declaration of Conformity – EMC
Meets intent of Directive 2014/30/EU for Electromagnetic Compatibility. Compliance was
demonstrated to the following specifications as listed in the Official Journal of the European
Communities:
EN61326-1：2013，EN61326-2-1：2013 EMC requirements for electrical equipment for
measurement, control, and laboratory use1, 2,3.
NOTE. Equipment may not meet the immunity requirements of applicable listed standards when test
leads and/or test probes are connected due to coupling of electromagnetic interference onto those
leads/probes. To minimize the influence of electromagnetic interference, minimize the loop area between
the unshielded portions of signal and associated return leads, and keep leads as far away as possible
from electromagnetic disturbance sources. Twisting unshielded test leads together is an effective way to
reduce loop area. For probes, keep the ground return lead as short as possible and close to the probe
body. Some probes have accessory probe tip adapters to accomplish this most effectively. In all cases,
observe all safety instructions for the probes or leads used.

Pollution degree descriptions
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 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.
