Radiated emissions

A laboratory of test has been realized inside the building with a plan of metallic reference. A movable antenna in height between 1 and 4 mt in comparison to the plan of reference, and rotating for the horizontal and vertical polarization. The antenna is set to a least distance of 3 mt by the equipment (EUT).
The spectrum analyser mesauress the difference among the total disturbance (EUT+anviromnent) and the present disturbance in the environment. In this way we measure the real emission of the equipment.

Test equipment list :
Antenna bilog Seaward, Antenna biconical Seaward, Spectrum analyser Seaward, Near field probe Seaward, Software Seaward, PC Manitronica S.r.l..

Main terminal interference votage
For this test is used a space inside the building  where there is a table with the LISN (Line Impedance Stabilization Network).

Test equipment list :
Spectrum analyser Seaward, Transient limiter Seaward, Capacitive coupling clamp Seaward, Software Seaward, PC Manitronica S.r.l..

Armonic and Flicker
An only equipmenmt is used for the two measures, with the necessary impedance of reference for the measure of the voltage fluctuations. The system is managed by pc

Test equipment list :
ORB Flicker and armonic analizer Seaward, Resistive load Manitronica S.r.l.,

Burst, Voltage Dip, ESD
An only equipment produces: impulses of burst, voltage dip and electrostatic discharges. The impulses of Burst are injected on the line of feeding and later, through the "capacitive clamp" in the lines of signals, control, etc.

The electrostatic discharges (positive/negative)  are applied to the EUT through the probe for electrostatic discharges in the following ways: in air, for contact.
