DIGITAL TERRESTRIAL TELEVISION HUNTER
TVHUNTER+
TVHUNTER+: Aligning antennas fast and easily
External antenna power
The meter includes a power supply for
external active antennas or preampli-
fiers. It is possible to select 5 V, 12 V,
18 V or 24 V depending on the require-
ments of the external device.
The TVHUNTER+ is a small handheld easy to use meter, that has
been designed for the installation of Digital Terrestrial Television
for DVB-T, DVB-T2 and ISDB-T/TB systems. The TVHUNTER has
become a widely popular tool for DVB-T antenna alignment. The key
factors have been its small pocket size and ease of use, still offering
proper measurements. As a natural evolution, TVHUNTER+ is now
available allowing full compatibility with DVB-T2 and ISDB-T/TB
standards for the High Definition digital terrestrial TV broadcasting.
It detects signals from any analogue or
digital terrestrial broadcast with the
built-in wide band detector. In this mode
the meter shows information about the
received signal power in the form of two
graphic bars with two different time cons-
tants and an audible indicator to help
align the aerial to the optimum detection.
SCAN.- The TVHUNTER+ allows a
broadcast search in DVB-T and DVB-T2.
Easy to use
In this mode the TVHUNTER+ shows information about the received digital channel
and programmes included in the service list as well.
2.- Identification
1.- Detection
It allows fine pointing the reception antenna, to optimise the digital measurements such as
channel power, MER, VBER and CBER on preselected channels. All information is
displayed on the screen in a very convenient way so that optimising the aerial alignment
becomes really easy. MER in particular is shown numerically and through a graphic bar as
well. VBER and CBER can be shown together or graphically.
