Fast spectrum
Espectro rápido e estável:
- up to 110 sweeps per minute against 50
of other meters will allow an easy and quick
dish alignment .
- 0.1 dB measurement stability at every refresh
compared to 2 dB of other meters.

SAFE
Shoulder strap supplied, so
that both hands are free
(more safety on rooftops)
and to allow an excellent
visibility of the displays.

SAT HELP
Press the HELP key and in a few seconds the
meter tunes and downloads pictures and
services of any unknown satellite carrier.

SAT FINDER
The satellite finder function is automatic.
Simply select three satellite transponders from
a satellite of your choice, slowly turn the
satellite dish and the meter will immediately
signal when it has found the required satellite.

DUAL SAT
This is the only one available on the market (tested by Eutelsat) it
allows you to quickly point multi-feed satellite dishes with two or more
LNB’s simultaneously, for example: HOT BIRD 13°and EUR OBIRD
9°, ATLANTIC BIRD 5°and ASTRA 19°, HOT BIRD 13°and
EUROBIRD 9°or any other combination of satellites.

ECHO
This analyzes the interference
hidden in DVB–T and DVB–H
digital channels (impulse
response) and supplies the
amplitude, the delay and the
distance in Km, from the
interference in order to be able
to minimize it.

BAR Spectrum
This allows you to visualize and measure, quickly and accurately,
the level and modulation (digital or analogue) of up to 100 channels
simultaneously. This is a unique feature in the market.

AUTOMEMORY
99 plans of 99 channels each. ROVER meters carry out an automatic
search of all TV channels, whether digital COFDM or QAM or analogue
simultaneously (other meters in the market do only COFDM or only
QAM separately).
15
MANUAL MEMORY
99 plans of 199 channels each, to allow you to memorize, manually or
by PC, any SAT-TV-CABLE-RADIO program/channel on a single
memory plan. For example: Radio, COFDM digital TV, QAM digital TV,
analogue TV, 8PSK digital SAT, QPSK digital SAT, analogue SAT.

AUTODISCOVERY
This automatically and instantaneously identifies, selects and
measures analogue or digital signals, without having to press
keys or wait 20 seconds.

including positioning functions and they
can also activate the spectrum when
the dish is moving.
