Two major advantages of using an accredited test house are confidence in and wide acceptance of the test reports, and faster Time to Market for your products. Accreditation is formal recognition of a test laboratory's:

• Technical competence to perform the tests covered by its Scope of Accreditation
• Quality system to ensure that it complies, and will continue to comply, with all the pertinent national/ international laws and standards.

The A2LA has Mutual Recognition Agreements (MRA's) with other Accreditation Bodies, countries, and economies around the world. Under these MRA's, these groups agree to accept testing/calibrations done by any A2LA-accredited test house/laboratory within its Scope of Accreditation as though they had done the work themselves. So you can legally enter many worldwide markets by preparing a simple Declaration of Conformity (DoC), backed up by the appropriate safety, electromagnetic compatibility (EMC)/ electromagnetic interference (EMI)/ electrostatic discharge (ESD), and other pertinent test reports, without having to retest your product for each market. For example, the FCC permits companies to market Class B personal computers and peripherals under a DoC if the EMC testing is done by an accredited laboratory.

Four major concerns when running EMC/ EMI/ ESD tests are:

1. Accuracy.
2. Thoroughness.
3. Speed.
4. Documentation.

We use the facilities and equipment of an A2LA-Accredited EMC laboratory that is associated with a major electronics manufacturer. We run FCC-/ CISPR- compliant Radiated Emissions tests in 10m and 5m Semi-Anechoic Chambers, that are available 365 days a year, and at any time of the day or night. For special Radiated Emissions tests-- weather permitting-- we can also use an Open Air Test Site (OATS) during first shift Monday to Friday. We run Radiated Immunity tests in a 3m Semi-Anechoic Chamber. We run all other tests in shielded rooms. Most tests are done under software control for repeatability and consistent data- collection/ reduction.

dBi Corporation also does:

• Consulting in EMC/EMI/ESD.
• Training in Design for EMC/EMI/ESD.
• Consulting and serves as an expert witness in legal cases that may involve EMC/EMI/ESD.

We like to become involved with products early in the design cycle, preferably before printed circuit board (PCB) layout begins. From our extensive experience in putting electronic products into mass production, both in designing products and in designing production testers for products, we can recommend:

• Simple, cheap ways to minimize emissions, and maximize immunity to noise, software bugs, and other disturbing factors.
• Safety and EMC/EMI/ESD standards you should strive to meet, so that your product(s) can be marketed worldwide.
• Ways to make your product(s) safe and reliable.
• Ways to design your product(s) so that they can be manufactured, tested, repaired, and serviced economically.
• Ways to choose components and manufacturing processes to give your product(s) a reasonable production lifetime.
• Ways to make your product(s) easy to bring up and debug.
• Ways to make your product(s) flexible, so that you can meet new and changing design requirements without massive redesign.
• Ways to design cables and PCB's to meet all of the above requirements at low cost and with low risk.

We can also help you find and fix many problems that arise during:

• The development of products and equipment.
• The transition to production.
• In the field.

1. Work.
2. Are safe and reliable.
3. Can be manufactured, tested, repaired, and serviced economically.
4. May be sold and used worldwide.
5. Can be easily adapted/enhanced to meet new and changing requirements.

Our President, John R. Barnes, is a Professional Engineer (PE) licensed in the state of Kentucky, a NARTE-Certified Electromagnetic Compatibility Engineer (NCE), a NARTE-Certified Electromagnetic Compatibility Technician (NCT), a NARTE-Certified Electrostatic Discharge Control Engineer (ESDC Eng), a NARTE-Certified Electrostatic Discharge Control Technician (ESDC Tech), a NARTE-Certified Product Safety Engineer (PSE), a Senior Member of the IEEE (SM IEEE), and an Advanced-class amateur radio operator. He has written three books: Electronic System Design: Interference and Noise Control Techniques, which was published in English in 1987 and in Russian in 1990; and Robust Electronic Design Reference Book, Volumes I and II, which came out in 2004. John has also written articles on designing electronics for electrostatic discharge (ESD) immunity for Printed Circuit Design and Conformity magazines.
