ADVANCED
The DISCOVERY family was specifically designed to meet the requirements of
installers and operators, who have to rapidly adapt to all the new, emerging,
digital technologies: DVB–S, DVB–T, DVB–C, DVB–H and also the new LNB’s
with S.C.R. (Single Cable Router) technologies.
POWERFUL
The DISCOVERY meter is the most powerful, compact and economical
RADIO–TV–SAT analyzer existing on the market and it allows you to carry out
any measurement, on both digital and analog signals, in terrestrial and
satellite bands, with direct SAT TRANSPONDER
navigation and dual LNB pointing.
MORE PERSONAL
SAFETY
The meter’s size and weight (only
2 Kg) facilitate transport and use.
If carried around your neck, the meter
allows perfect viewings and readings,
keeping both hands free. This not only
simplifies operation in normal working
conditions, but also guarantees total personal
safety even in the most critical situations (on roof
tops, ladders, etc.).
FAST and AUTOMATIC
The DISCOVERY meter is the first of its kind to include a built-
in, 32 bit, 100 MHz, ARM-7 microprocessor. This, together with
a high capacity memory, enables you to identify, analyse and
automatically and instantly store the digital and analog TV signals,
according to the relative standard used in your country and the
meter automatically supplies the measurements of the digital
signal quality: FAIL-MARG-PASS.
MORE MEMORY
The high capacity FLASH memory allows you to memorize up to
200 plans, which accommodate many thousands of TV channels
and pre–loaded satellite transponders.
USB PORT
A USB-2 port permits PC control, using special and sophisticated
software, which simplifies the meter’s operation (special, pre-
memorized channel plans, “Data Logger” downloads, implementation
of new software releases via internet, etc.)
DUAL DISPLAY
Two displays, one graphic for spectrum/measurements and one 4”
TFT color for pictures allow you to obtain, simultaneously and
separately spectrum/measurements and full pictures. This guarantees
perfect measurement vision both in full sunlight and in the dark.
FULL OPTIONAL ACCESSORIES
The meters are supplied with a built-in shoulder strap, useful
hard case for transport, batteries with a 3 to 4 hour autonomy
and a charger to charge the batteries from your vehicle or
from mains etc.
COMPLETE AND SIMPLE NAVIGATION
In order to explain the simplicity of the meters’ operation, we describe below
how to navigate in TV and SAT bands.
NAVIGATION IN TV BAND
(including channel PLANS from all over the world).
These meters can operate in three ways:
a) NAVIGATION IN THE CHOSEN COUNTRY PLAN.
By navigating manually in the country’s channel PLAN (for example,
channels 21-22-23, etc.), the meter instantly recognises the type of signal
(analog or digital) and immediately supplies all the various measurements
(level, MER, SNR, BER, NOISE MARGIN, QUALITY) and spectrum analysis.
It also supplies the network name, the bouquet name, the encryption
system and, last but not least, the names of all the programs, services
and audio and video PID’s, contained in the bouquets, even if they are
encrypted. An interesting feature is the possibility of navigating in spectrum,
using channels, and automatically obtain the level measurement and
position the “marker” on the video carrier. In the same way power
measurements are supplied for digital channels and the “marker” is
positioned in the center of the channel.
The DISCOVERY is the only meter that automatically sets the REF LEVEL
(level scale) on the spectrum.
b) NAVIGATION IN THE CUSTOMER PLANS, stored manually using the
meter, or preloaded using a PC, via the USB port.
c) AUTOSCAN (complete automatic auto-memorization function). Basically
when connecting an antenna to the meter and after
setting the minimum threshold at the required
level, the meter automatically recognises,
identifies and stores the various programs
received in this location, generating
an “AUTO” memory plan, which
can be selected from N.1 to N.99,
for each installation or for each town.
NAVIGATION IN SAT BAND
(including the data of the main satellites in Europe/Asia/America and
all their relative transponders).
a) NAVIGATION IN THE CHOSEN SATELLITE TRANSPONDERS (for
example ASTRA 19°, already pre-stored on board).
satellite name and relative orbital position have been
selected, you can navigate directly using the
number of transponders and/or relative
frequency. The transponders are listed in
increasing frequency values and have all
the LNB parameters pre-stored: L.O. and
band, DiSEqC and the new “SCR” LNB’s
for 4 or 8 users (Single Cable Routers),
as well as multi-switches with 4-
8-12 or 18 cables.
b) NAVIGATION IN THE MEMORY
PLAN (for example PLAN 46, stored
manually by the user or using a PC).
This allows you to navigate in the
various programs from 1 to 199
according to the sequence and
settings stored by the user.
In both cases the meters automatically
supply all the power measurements for
digital transponders, and the level for
analog ones, as well as supplying MER,
EVM, BER, NOISE MARGIN, QUALITY
measurements and the network name,
bouquet, the orbital position and encryption
system. Last but not least, the meters supply
the names of all the programs (services) and
Audio and Video PID’s contained in the
bouquet, even if they are encrypted.
Another important feature: it is possible to
navigate in spectrum mode, with
transponders, memory programs or
frequencies.
The meter automatically supplies the level
measurement for analog transponders and
the power measurement for digital transponders, already correlated to the
relative Symbol Rate value (without having to position the band marker), this,
thanks to the quantity of pre-stored data in the meter and excellent calculation
power. It is also the only meter that can automatically set the REF LEVEL
(level scale) of the spectrum.
NOISE MARGIN QUALITY MEASUREMENT (unknown):
this is another exclusive ROVER measurement.
Pointing the antenna and/or satellite dish to the maximum level does not
always mean the maximum signal quality. In fact, in the case of interferences
with the analog TV signal, it is possible to carry out pointing for the best and
clean picture and not always for the maximum level. With digital signals you
should get used to measuring the NOISE MARGIN and increase it to the
maximum value possible (minimum 2 dB for SAT and 6 dB for digital terrestrial)
to guarantee a good and stable reception in time.
