The Physical Layer Pipe con-
cept is being used on the currently
have both hands free while
using the analyzer. Thanks
to the synthetic carrying
case, the HD-T2 is nicely
protected from rain, sprin-
klers and dirt.
A Quick Start Guide leaflet
as well as a detailed user
manual describe in detail
all of the new HD-T2’s func-
tions. All in all, the shipping
package and its workman-
ship left us with a very posi-
tive impression. Horizon has
once again shown their dedi-
cation to quality.
After powering it up, the
background lighting for the
perfectly readable display
comes on that works great
whether you’re in a dark at-
tic or on the roof in bright
sunshine.
The HD-T2 operates with a
total of three labeled buttons
(
ON, OFF and OK) and two
unlabeled buttons whereby
four of them make up a cross
and the OFF button does
more than meets the eye.
Holding down the OFF but-
ton with the analyzer turned
off brings up the configura-
tion display. This method
helps to prevent unknowing
or accidental changes to the
settings.
A multitude of settings
capabilities are available in
the configuration menu. It
all starts with the brightness
and contrast of the display,
measured frequency as identified by the
HD-T2 with the PLP label on the display

The Log All function searches the
entire frequency range and stores all of
the reception parameters of any active
frequency that is found

The Favorites function allows quick
access to the most recently selected
broadcasting location

Three spectrum modes as well as the
constellation diagram are available

The Slope Test function displays both
of the active DVB-T2 frequencies next to
each other in bar graph form
23.
The Slope Test function displays the
signal levels of the two active DVB-T2 fre-
quencies next to each other, the user can
instantly see the difference in the signal
levels

The HD-T2 can supply power to exter-
nal antenna amplifiers with +5V or +12V
