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.
