REGULATORY NOTES

 

 

FCC PART 18

 

 

This device complies with part 18 of the FCC rules for non-consumer industrial, 

scientific and medical (ISM) equipment.

This instrument is enclosed in a rugged metal chassis and uses a filtered power entry 

module (where applicable). The main output signal is provided on a shielded connector 

that is intended to be used with shielded coaxial cabling and a shielded load. Under 

these conditions, the interference potential of this instrument is low.

If interference is observed, check that appropriate well-shielded cabling is used on the 

output connectors. Contact Avtech ([email protected]) for advice if you are unsure

of the most appropriate cabling. Also, check that your load is adequately shielded. It 

may be necessary to enclose the load in a metal enclosure.

If any of the connectors on the instrument are unused, they should be covered with 

shielded metal “dust caps” to reduce the interference potential.

This instrument does not normally require regular maintenance to minimize interference

potential. However, if loose hardware or connectors are noted, they should be 

tightened. Contact Avtech ([email protected]) if you require assistance.
