BRUEL & KJAER 2006 User Manual

Note: This measuring result is reached on the assumption that the electrical
field is homogeneous and that the antenna is ideal. Therefore, an absolute
accuracy higher than ± 3 dB should not be expected. However, as this
accuracy will be sufficient in most cases, the method proves to be quick
and simple as the 2006 needs only one calibration covering the whole fre-
quency range. So when changing frequency only the antenna need to be
adjusted.
A dipole antenna becomes inpractical for measurements at frequencies lower
than about 50 MHz because of the length that would be required. For these
lower frequencies therefore, it will be found to be much more convenient to
construct a frame antenna and calibrate it in a known field. It should be
mentioned here that should a higher accuracy than ± 3 dB be required then
the method of calibrating the antenna in a known field, whether it be frame
or dipole , should be adopted. Furthermore it should be noticed that the
Heterodyne Voltmeter Type 2006 can only be used as a fieldstrength meter
when the fieldstrength of the measured signal is strong compared to the
other signals at the measuring position. This is to be sure that noise and
false signals from image -a nd cross modulation do not interfere with the
measurement.
