1.12 Emission
measurements All electric and electronic devices are potential generators of Electro-
Magnetic 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 CA0010 is that the instrument
shall be full compliant with all the relevant standards and at the same time
simple and reliable to use, to be the best ancillary for the 9010F Emi
Receiver and to allow the evaluation of any possible other click meter.
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 9010F 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 Click Analysis and PMM Click Generation software packages
allow an immediate use of the instrument without any training or special
difficulties: the operator can concentrate just on analyzing the
measurement results.
Moreover, these pieces of software have also been designed for a fast and
easy installation on a suitable PC running Windows
™ operating system
and with at least one free USB 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 9010: the input signal should not
exceed the maximum level indicated in the main specifications in
chapter 1.
Also do not apply any signal to RF generator output connector.
