Emissions
testing involves the measurement of radiated and conducted RF energy generated
by an electrical apparatus. In almost all markets, permissible electromagnetic
energy is limited to a defined level. Products that intentionally
transmit RF energy often require formal certification by a National authority,
while most other electronic devices must meet a general limit for unintentional
RF noise.
Product
Safety Engineering (PSE) maintains two open area test sites(OATS) for emissions
testing, one used primarily for diagnostic and engineering work while the second
is dedicated to formal testing. Open area testing is still the preferred method
by agencies worldwide. Unfortunately unwanted RF signals (ambient noise)
from outside sources such as TV stations or "downtown city" noise can
hinder the efficiency of an OATS. PSE overcame this hurdle by constructing
our custom test site on over 125 acres of land far from any significant sources
of noise. Located amidst the cow pastures and orange groves of central
Florida between Tampa and Orlando, PSE maintains a premium location for open
area 3
to 30 meter RF testing.
It
is not uncommon for a product to exceed the limits for unintentional
emissions. In some cases the non-conformance can be overcome with very
simple modification, while other devices may require a significant
re-design. In all cases, the expert engineering team at PSE can
help. Many of our clients have commented on the importance of a trusting,
long-term relationship with an expert emissions engineer who can assist them in
overcoming the hurdles of regulatory compliance. At PSE we strive to build
relationships, not just perform tests.
