All electric and electronic devices are potential generators of Electro-
1.12 Emission
Magnetic Interference (EMI).
measurements
The term EMI thus refers to the electromagnetic energy emitted by a device
which propagates itself along cables or through the air and couples with
other devices that are present in the surroundings.
These electromagnetic fields (conducted or radiated interferences) may
generate interfering currents and voltages into nearby equipment and
therefore can cause possible malfunctions.
In order to prevent and control such interferences there are nowadays a
number of national and international standards, like IEC and CISPR, which
specifies limits and methods of tests. Moreover, within the European Union
the application of several European Norms on Electromagnetic
Compatibility is enforced by law and therefore the commercialization and
use of all the electric and electronic equipment is subject to the
measurement of the EMC characteristics, which must be within well defined
limits.
The design approach adopted for the PMM ER8000 is that the instrument
shall be innovative, full compliant with all the relevant standards and at the
same time simple and reliable to use, to be the base building block for any
possible emission system to measure and evaluate any electric or
electronic device from the very first design stages to the final certification.
The need to precisely measure the conducted and radiated EMI noises
forces the equipment manufactures to use reliable equipment to verify the
limits imposed by the relevant standards and/or enforced by local rules.
In this view the PMM ER8000 receiver is the ideal solution from prototype
debugging to final certification, as it fully meets all the performance criteria
dictated by these standards, although it remains small, lightweight and very
easy to use.
The PMM ER8000 Utility control software permits an immediate use of the
instrument without any training or special difficulties: the operator can
concentrate just on analyzing the measurement results.
Moreover, the PMM ER8000 software has also been designed for a fast
and easy installation on any PC with the Windows™ operating system and
with at least one free USB or Serial Port.
The device under test (DUT) must be installed according to the procedures
indicated in the constructor's manual and normal operating conditions
respected.
Be sure not to overload PMM ER8000: the input signal should not
exceed the maximum level indicated in the specifications (see § 1.7) .
Also do not apply any signal to RF LISN output connector.
