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.
While this hardware is compliant with the applicable regulatory EMC requirements, there is no
guarantee that interference will not occur in a particular installation. To minimize the potential for
the hardware to cause interference to radio and television reception or to experience 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, you are encouraged to try to
correct the interference by one or more of 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, for marine use or in heavy industrial areas.
Refer to the hardware’s user 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.
