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.
