11.13 Emission
measurements
All electric and electronic devices are potential generators of
ElectroMagnetic Interference (EMI).
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 9030/9060/9180 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 9030/9060/9180 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 9010 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 9010 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 9030/9060/9180: the input signal should
not exceed the maximum level indicated in the main specifications in
chapter 11.
Also do not apply any signal to the 9010 or 9010/03P/30P/60P input
and generator output connectors.
