SPECTRUM ANALYSER
EMC Prequalification
Spectrum Analyser and Near-field Probes
Use near-field probes
The different fields measured this type probe can used locate source high-
frequency electromagnetic fields which can cause disturbances.). Insensitive external disturbances, these
probes measure the intensity the field directly associated with the current flowing the conductors.
In "radiated mode", proximity probe can used measure all the electromagnetic fields present the air
(example 2).
Active H-field probes operate observing the disturbance currents.

Above: use the proximity probe. They can
be used with spectrum analyser equipped with Peak Q-Peak detection modes. It
is ideal for detecting disturbances originating from surfaces which are difficult access.fr
. also possible observe very slight disturbances.
Inspection printed circuit board identify
emission frequencies and levels relation the EMC
standards
Below: use the contact probe and use of
the amplifier connected directly the MTX 1050. For greater accuracy, these HX0082 probes can coupled with HX0083 amplifier (dB) reduce
the noise floor level.
These modes allow measurements the context EMC prequalification tests.
In "conducted mode", contact probe will used detect magnetic fields emitted vertically from flat surfaces
(example 1). can used for precise measurements clearly-defined areas (floorplan, trace, screening, etc.metrix
