Everyday use
No test report is complete
without finding out what a
device is worth in the real
world. Coincidentally, analog
terrestrial broadcasting was
switched off in April in Por-
tugal and our test center was
still without a DVB-T antenna.
So using the DS2400T for
aligning our rooftop antenna
was the logical choice. To
be frank, I can cut this long
story very short because with
a top-notch signal meter like
that all I had to do was en-
ter the required channel (754
MHz, irrespective of the lo-
cation in Portugal thanks to
a Single Frequency Network
DVB-T system) and in less
than one minute the antenna
was perfectly aligned.
Ironically, this brilliant re-
sult even caused some prob-
lems for my real-world test
– how can you possibly show
screenshots of MER and BER
measurements when there
are virtually no errors in the
signal? All you get is a line
hovering around the zero
value. In the end I had to use
my good old stub antenna
again, not for achieving bril-
liant reception but for receiv-
ing a less than perfect signal
for test purposes. In addition,
I used the DS2400T for meas-
uring all antenna sockets in
my house and even detected
a faulty antenna cable that
had caused noise with some
channels.
Conclusion
I am absolutely convinced
by this meter and can recom-
mend it without reservation.
It’s a small, lightweight device
that still offers all options a
professional installer will ever
need for DVB-T, DVB-C and
CATV. The range of features
and measurement functions
is truly unique and will help
you detect potential flaws
quickly and reliably. But you
don’t need to be on the hunt
for problems in order to fully
appreciate the capabilities of
the DS2400T. Routine instal-
lation jobs become child’s play
too and thanks to the supplied
Toolbox software it is even
possible to draw up compre-
hensive documentation or to
monitor a reception system
in real time. This can also be
done remotely via the Internet
with the help of Remote Desk-
top Protocol. While the meter
itself is awe-inspiring, it’s also
the small additional things
that propel the DS2400T right
to the top of our pick list: The
battery pack supports mobile
use for hours on end, and the
supplied charging unit replen-
ishes the battery in as little as
two to three hours. We used
this handheld on and off for
about three weeks and not
once did we experience any
malfunction. It just worked as
advertised. To be honest, it
exceeded our expectations by
far. We’d be hard pressed to
come up with some criticism,
and the only thing we were
missing was watching the TV
channel on the meter’s dis-
play. But let’s be honest, this
is a feature that professional
installers simply don’t require
and Deviser has stayed true
to its motto for the DS2400T:
A top-notch and feature-rich
meter for professional use,
delivering accurate measure-
ment results rather than use-
less gadgets and eye-candy.
This is exactly what the
DS2400T is all about. We can
wholeheartedly recommend
this meter for all DVB-T, DVB-
C and CATV jobs.
