4.11 Additional
functions provided
by EHP200-TS EHP-200A electromagnetic field analyzer provides Electric and Magnetic
field selective measurement in the 9kHz – 30MHz frequency range.
Even though there is no difference from EHP-50G regarding minimal
physical overall dimensions and sensor positioning, a high frequency
selective receiver is housed within this product.
Additional settings and functions are therefore available.
Regarding settings, Span can be set as desired within the entire frequency
range and required RBW filter can be selected down to 1kHz allowing thus
optimum selectivity.
As requested by reference standards, Average value can be automatically
calculated over 6 minutes as well as over customer defineable time periods.
An important advantage, which is provided thanks to the Dual (E and H),
Tri-axial sensor technology implemented in EHP-200A is the new concept
of power density calculation which, unlike common practice, makes use of
both E and H real measurements providing thus accurate results which are
still valid in both Near and Far Field conditions.

Both electric and magnetic fields can be displayed on the same graph.
Fig.4-9
Power density spectrum is calculated over real electric and magnetic field
measurement and therefore applicable to both far and near field conditions.
