One of the First
DVB-T2 Signal Analyzers
TEST REPORT
DVB-T2 Signal Analyzer
The transmission of high-
resolution channels (HDTV)
using the classic terrestrial
distribution method in DVB-T
is only possible on a limited
basis. Thanks to the sub-op-
timal bandwidth usage only
a few HD channels can be
broadcast on those few fre-
quencies.
It’s for this reason that
DVB-T’s successor DVB-
T2 is gaining popularity in
many countries: this stand-
ard guarantees not only the
highest possible error cor-
rection and thereby a very
small likelihood of interfer-
ence in the transmitted sig-
nal, but also very efficient
bandwidth usage allowing
providers to achieve much
higher data transmission
rates on a single frequency.
It only makes sense then
that signal analyzer manu-
facturers have to keep pace
with these developments
and upgrade their products
to the latest technology.
Horizon has once again
taken charge and is one of
the first companies in the
world to market a DVB-T2
compatible signal analyzer.
Horizon has stayed true to
form in terms of the appear-
ance of this new signal ana-
lyzer; it resembles all of the
other analyzers that have
been made over the years.
It consists of a plastic
housing 17 x 16.5 x 6 cm in
size with a 5 x 2.5 cm LCD
display (128 x 64 pixels) on
the front side. Alongside the
display are five buttons to
operate the analyzer and an
“
F” jack on the front serves
as the DVB-T/T2 signal in-
put (naturally the analyzer is
also backwards compatible
to DVB-T).
Power to the analyzer is
supplied by two connections,
one is a normal AC connec-
tion on the back of the ana-
lyzer that is rated for 100-
240
VAC, and the other is a
12
VDC jack on the right side
of the housing which can be
used with the included ciga-
rette lighter adapter. In this
way you can use any power
outlet with the HD-T2 as well
as the power outlet in your
car.
And while we’re on the
subject of power sources,
obviously, power doesn’t
need to be connected while
the analyzer is in use; it has
an internal Li-Ion battery
rated at 2.4 Ah that reliably
powers the analyzer any-
where you need it.
The rechargeable battery
is located on the underside
of the unit and is easy to
access behind a flap. This
makes it simple to swap out
the battery if needed or to
completely remove the bat-
tery in case of longer peri-
ods of inactivity.
Thanks to this intelligent
construction and the two
charging methods, Horizon
can virtually guarantee that
the user won’t wake up to a
dead battery or run into any
surprises while on the job.
And last but not least,
there’s also a USB interface
for connection to a PC.
The analyzer needs about
2-3
hours for it to be com-
pletely charged. Before us-
ing it for the first time, Ho-
rizon recommends charging
the HD-T2 at least for this
time, perhaps one or two
hours more if possible. This
makes sure that the as-yet-
unused battery can provide
its full capacity.
At only 1200 grams (2.6
Lbs), the new Horizon sig-
nal analyzer is comfortably
light and is delivered from
the manufacturer in a black
synthetic carrying case that
can be fitted with a carry-
ing strap also included in the
package.
This allows the user to
