Radiated Emission and Immunity testing
3-5
3.3 Environmental
testing
The PMM BC-01, BL-01, LP02, LP03, LP-04 and DR-01 antenna can also
be used on environmental testing for narrow band electromagnetic field
exposure testing.
The wide frequency range and the low VSWR both allow accurate tests
with linear polarization.
For this kind of test the antenna must be used according to the following
test setup, the receiver must have a good selectivity performance and must
be tunable on the frequency or frequencies under investigation, a spectrum
analyzer can be used instead.
The RF attenuator is normally installed as closest as possible to the
antenna to improve the VSWR performances and then the precision of the
measurement.
