Over the years our people have gained significant insight to the proper methods of testing
and have set new standards for performance testing of RF Shielded test facilities and anechoic test chambers. ATSI has worked on numerous
shielding projects worldwide and can test any facility regardless of size or location. We have tested countless enclosures constructed
of demountable panel systems such as those manufactured by Universal Shielding Corporation and Ray-proof Shielding Systems, and many
large welded steel facilities. Although these systems are designed to meet the most stringent attenuation requirements specified by
the US Government, there are always some minor problems, which can only be identified during the testing process. We are consistent
in finding these problems and offering the correct solutions for the customer. Other inexperienced testing companies and/or
personnel may not have the necessary expertise to identify such problems.
In addition to testing large government
owned facilities, ATSI also provides RF testing services to the Magnetic Resonance Imaging (MRI) industry. We have tested
MRI facilities all across the nation and stand ready to respond within 24 hrs to any location in the continental United States. ATSI also provides troubleshooting services for clients experiencing a problem with their MRI images. Most times the RF shield
is suspect of leaking RF and causing imaging artifacts to the MRI. ATSI can determine if the shield is the cause of the problem
or if other RF/EM interference may be the culprit.
ATSI has performed various EMI and EMC tests from MIL STD 461 field
testing the V-22 Osprey Flight Simulator, a 35 million dollar unit, to conducting EM Interference studies on mobile and stationary
MRI units. We have also provided troubleshooting efforts to EMC test chambers that are experiencing outside interference. We have located and corrected these problems for both commercial and government clients. ATSI has also conducted numerous certifications
of test chambers for ANSI C63.4 Site Attenuation and IEC 61000-4-3 Field Uniformity Measurements. The chambers ranged from pre-compliance
chambers, FCC and Canadian listed chambers, to
Anechoic chambers used for government test facilities. These chambers ranged in
size from small 12’L x 20’W x 12’H high control rooms and test chambers to the extraordinary EMC test facility for testing military
aircraft, that is 180’L x 180’W x 80’H.
ATSI staff members have provided
RF shielding effectiveness testing for HEMP facilities since 1993. The RF Shielding effectiveness radiated testing and
SELDS testing associated with large steel RF shielded HEMP facilities encourages innovative methods for testing these large facilities. ATSI’s innovative staff has always been able to come up with unique solutions to difficult testing problems on these extremely large
HEMP and EMI facilities. ATSI has been the quality control and certifying agency on HEMP/EMI projects nationwide, including
SENSITIVE COMPARTMENTED INFORMATION FACILITIES (SCIF)
