3.6. AT3000 calibration
This passive device does not contain any parts whose characteristics deteriorate over time, however the
recommended calibration interval depends on intensity of use or on undesired accidental events (falling, crushing,
contact with liquids). Generally the calibration procedure is carried out against the sample in an environment free
of interfering field. Calzavara - Clampco Sistemi supplies the antenna complete with a calibration certificate issued
by its radio-electric laboratory. This is obtained in controlled environments (TEM cell and anechoic chamber) by
comparison with the laboratory primary samples, calibrated in SIT accredited or equivalent (EA) laboratories.
The correct position is represented in the figure below. Rotate the antenna on its axis until the dipole axis is in a
horizontal plane. In Figure 9, the
X
antenna is ready to be calibrated supposing that a horizontal polarization
launch is used. Now the other two antenna factors (K
Y
, K
Z
) can be measured in sequence by manually rotating the
support through 120° in relation to the base of the support.
