"Antenna Analyzer plus" is a multifunctional measuring instrument, most useful for
amateur radio activity. Its size allows you to easily take it for relocation as well. The
panel size is 115 x 75 mm fitting into a small box of
size eg. 125 x 80 x 25 mm. Its main function is put
into effect by the two RF impedance meters - called
together the antenna analyzer - which can measure
phase true complex impedance between the main
antenna poles, ranging
from 100kHz to
200MHz and 425MHz
to 445MHz. Numeric
results are also displayed graphically. In addition to the
detailed measurement of antenna parameters, it can be
used as an inductance and capacitance meter as
well, with which you
can measure parts
from 10nH or 1pF. Another interesting feature
available is
spectrum display
function, with
which you can
visualize the full
output spectrum
of the transmitter within the whole 100kHz to
200MHz and 425MHz to 445MHz frequency
interval.
Furthermore, the device includes a dual-channel
signal generator, which can produce sine signal from 100Hz to 200MHz and 425MHz
to 445MHz, freely set for the two independent channels
with a frequency resolution of 1 Hz. Moreover, the
relative phase shift between signals of the two channels
can be controlled by 1 degree increments from 0 to 360
degrees. Perhaps the most interesting part of the
instrument is the
control and display of
measurement results.
On the instrument
itself, there is no
display and no
controls, so it can be
placed directly on
the antenna base point while remote
controlled from a distance up to 50m, including
evaluation of the results. Control of the instrument is possible using any WiFi
enabled device with installed web browser. This could be notebook, tablet or even a
smartphone, and the solution adopted is "platform" independent, so it should not
matter if the controlling device is running Windows, Linux, Android or iOS operating
system.
