the antenna we finally catch a
signal, but is it really beamed
from the satellite we’re aim-
ing at? The CB200 HD has a
solution for that scenario –
it’s called Automatic Satellite
Detection and works like a
charm. Thanks to the meter’s
pre-stored satellite and tran-
sponder database the device
is capable of identifying the
source satellite of an incom-
ing signal almost instantly.
Of course we tried out that
feature several times and
can confirm that it worked
surprisingly reliably, even
though you should always
bear in mind that the CB200
HD can only detect those
satellites that are included
in the pre-stored list or have
been entered manually. So
if you work with some less
widely received positions
chances are the meter might
not be able to identify those.
The DiSEqC search feature
turned out to work just as
smoothly in our test – us-
ing it allows the CB200 HD to
read out the entire configu-
ration of a DiSEqC 1.0 or 1.1
switch. In combination with
multi-focus antennas this is
a great benefit and a hugely
welcome tool. DiSEqC detec-
tion helped us save valuable
time, which in the real world
translates into money that
can be saved. Not a bad deal,
don’t you think?
Then there is a menu item
with the somewhat mysteri-
ous description Packet Con-
trol. What’s that all about?
We believe it hides an ex-
tremely helpful feature that
allows you to monitor signal
level and signal quality of up
to eight transponders at a
time. If you’re dealing with
complex distribution setups,
for example, Packet Control
will quickly identify any sig-
nal tilt on one of the tran-
sponders. How does signal
tilt appear in the first place?
Coax cables exceeding a
certain length unfortunately
tend to cause more attenu-
ation on higher frequencies
than on lower frequencies,
which in turn may prompt a
low-threshold satellite tuner
to over-modulate those lower
frequencies. With the help of
the CB200 HD and its simul-
taneous presentation of up to
eight transponders this prob-
lem can be detected right at
the outset and can be recti-
fied using a sat slope, for ex-
ample. A sat slope is a com-
ponent that is looped into the
coax cable in order to add low
frequency attenuation so that
in the end you arrive at a per-
fectly balanced distribution
signal.
The CB200 HD can be used
to control a DiSEqC motor
using both the DiSEqC 1.2
and DiSEqC 1.3 protocols,
