Today, society is heavily reliant on electronic devices. The convenience provided by them has made life easier is many ways. EMC testing of electronic equipment is vital to ensure their smooth functioning as well as determine the effects they have on other devices and the environment. We, Com-Power Corporation, have been manufacturing a wide range of testing equipment that provide accurate measurements and help meet regulatory requirements. We are a leading Manufacturer and Exporter of a wide range of EMC Test Equipment and EMC Test Instruments including but not limited to Near Field Probes, Absorbing Clamps, Power Amplifiers, Surge Generators, Telecom Test System and Immunity Systems. In order to keep providing our customers with the very best, we have set up a research laboratory that is tasked with product evolution and process optimization.
What Is EMC?
compatibility or EMC is the ability of electronic products to perform
in their intended environments. The test checks how well an equipment
holds up and performs while under the influence of electromagnetic
energy from other products. EMC provides information regarding
electromagnetic emissions of various equipment and how they interfere
with other machines. The test equipment we manufacture such as Antennas
and Comb Generators help check various regulatory standards regarding
noise and a machines ability to sustain performance while being
interfered with by electromagnetic emissions from other products. Our
equipment can be used to detect the cause and effects of various noise
on electronic products. The difficulty in understanding EMC lay in the
noise levels that may vary over a large range. The other major issue
faced by EMC tests is that electromagnetic emissions can be caused by
both radiated noise and conduction. Noise is thus able to travel as
radiated noise, conducted noise or a combination of the two.
History Of EMI, RFI and EMC
use of electronic products started the problems concerning
electromagnetic emissions. In order to deal with electromagnetic
disturbances on field telegraphs, the Germans passed the Law off
telegraph in the German empire. The interference in the early days were
most caused by radio frequencies and were thus termed as RFI. It was
later understood that noise could be caused at any frequency and the
term RFI was broadened into EMI. The source of the noise was termed as
the culprit whereas the affected circuit was called the victim. Affected
circuits needed to be redesigned in order to make them capable of
functioning under the influence of electromagnetic emissions. It was
found that in some cases the source and affected circuits would belong
to the same device, thus their would be no culprit and victim circuits.
EMC & Product Reliability
was not until 1940 that the effects of interference were not completely
realized, when the electronic equipment used on naval ships witnessed
an increase. Sensitive receivers and powerful transmitters began to be
used close together. This not only led to various problems but also
provided a deeper understanding about the effects of noise on various
Performance of various electronic products can be severely impaired by
electromagnetic emissions, thus taking EMC into account is vital. This
holds true for both complicated electronic circuitry such as those used
in aircrafts and ships as well as those used in televisions, mobile
phones, etc. Such problems related to electromagnetic disturbances can
be disastrous in places such as chemical plants. A deeper understanding
of noise and its related issued by conducting EMC tests can help design
products that perform well under their influence.
EMC-Compliance Testing & Its Benefits
electronic equipment produce noise that can result in electromagnetic
interference in other equipment and in circuits within it. Improper
design of circuits can lead to problems in their functioning if they
come under the influence of electromagnetic noise. Furthermore, if a
device acts as a source of noise, it could lead to interference with the
functioning of other electronic equipment. Compatibility with the noise
produced by other devices is known as EMC. Thus EMC testing is vital to
any and all electronic equipment and provides consumers with
information regarding their use.
from performance related benefits, EMC testing helps meet requirements
specific to each industry. Various compliance standards such as CISPR
22, MIL-STD-461, etc. that are necessary for doing business can be met
using these tests. Regular test can help create integrated systems,
mitigate risk and eliminate overdesign issues. Testing can be performed
in-house, depending on whether the client is a manufacturer or a seller
of the product. The CE mark is used as a self declaration in Europe. The
accreditations for North America may include Industry Canada testing
and FCC. Pre-compliance testing can help save money as most electronic
devices tend to fail their first EMC test.
EMC Compliance Testing Equipment & Calibration
testing can be broadly classified into two categories, namely, immunity
and emissions testing. As the name suggest, emissions test help analyze
the noise being produced whereas immunity testing provides an insight
into how the device handles exposure to electromagnetic interference.
Some of the various benefits of using our equipment are as follows:
at Com-Power, manufacture equipment for both types of testing such as
tuned antennas and Comb Generators that are used to check both emissions
and immunity of devices.
