Electromagnetic Compatibility Information
This hardware has been tested and found to comply with the applicable regulatory requirements
and limits for electromagnetic compatibility (EMC) as indicated in the hardware’s Declaration
of Conformity (DoC)
1
. These requirements and limits are designed to provide reasonable
protection against harmful interference when the hardware is operated in the intended
electromagnetic environment. In special cases, for example when either highly sensitive or noisy
hardware is being used in close proximity, additional mitigation measures may have to be
employed to minimize the potential for electromagnetic interference.
When this symbol is marked on a product, refer to the hardware documentation for
information about precautions to take.
This hardware complies with the applicable regulatory EMC requirements, but some
interference may occur in particular installations. To minimize interference with radio and
television reception and to prevent unacceptable performance degradation, install and use this
hardware in strict accordance with the instructions in the hardware documentation and the DoC
1
.
If this hardware does cause interference with licensed radio communications services or other
nearby electronics, which can be determined by turning the hardware off and on, NI recommends
that you try the following measures:
•
Reorient the antenna of the receiver (the device suffering interference).
•
Relocate the transmitter (the device generating interference) with respect to the receiver.
•
Plug the transmitter into a different outlet so that the transmitter and the receiver are on
different branch circuits.
Some hardware may require the use of a metal, shielded enclosure (windowless version) to meet
the EMC requirements for special EMC environments such as marine and heavy industrial areas.
Refer to the hardware documentation and the DoC
1
for product installation requirements.
When the hardware is connected to a test object or to test leads, the system may become more
sensitive to disturbances or may cause interference in the local electromagnetic environment.
Operation of this hardware in a residential area is likely to cause harmful interference. Users are
required to correct the interference at their own expense or cease operation of the hardware.
Changes or modifications not expressly approved by National Instruments could void the user’s
right to operate the hardware under the local regulatory rules.
