General Information
DB7002 is a revolutionary solution that combines in a single, high-precision tool the most
important functionalities of two separate types of product. To achieve that, our engineers have
equipped this model with two independent tuners - one for FM and one for DAB/DAB+, allowing
for the device to perform both FM and DAB/DAB+ monitoring in parallel. It provides detailed and
accurate measurement of all of the most important signal parameters and also boasts two loggers
with 24 channels apiece for FM and DAB/DAB+. The recorded information is stored in log les
on an SD card for easy future analysis and can easily be downloaded via a standard FTP client.
As a product that incorporates DAB/DAB+ monitoring capabilities, DB7002 fully meets the
ETSI EN 300 401 DAB standard and oers support for Program Associated Data (PAD), as well
as all standard bitrates and VBR, and automatically displays live metadata.
As an FM monitoring tool, DB7002 also provides powerful signal processing capabilities
through sophisticated DSP algorithms and oers a Loudness Meter, which allows for measurements
to be shown as dened by ITU BS.1770-4 and EBU R128 recommendations.
To make sure the transmission is not interrupted, there are local alarm options and online
notications via rear-panel alarm GPOs, E-mail and SNMP in case there is audio loss or a change
in the signal.
DB7002 can also be managed without eort. It is easy to program via the front-panel menu or
remotely through your PC, tablet or smart phone via a standard web browser; iOS and Android
devices are also supported. The high-resolution OLED graphical display and the ultra-bright LED
bar graph indicators allow for easy reading of the main signal parameters. A user-friendly front
panel menu in addition to the set of four soft buttons provides easy navigation and quick access to
each function.
DB7002 is denitely a must-have. Its two independent tuners set it apart from any other product,
while its eectiveness and precision make it the perfect monitoring tool.

Before you start
SAFETY WARNING
After removing any housing parts and electronic assemblies it is possible to get access to live
parts. It is essential to ensure that the subsequent safety rules are strictly observed:
• Servicing of electronic equipment must be performed by qualied personnel only.
• Before removing covers the equipment has to be switched o and the mains cable unplugged.
• When the equipment is open the power supply capacitors have to be discharged by the help
of a suitable resistor. During servicing unprotected and operating equipment:
- never touch bare wires or circuitry;
- use insulated tools only;
- never touch metal semiconductor cases because they may carry high voltages;
• For removing and installing electronic components, please follow the recommendations
concerning the handling of MOS components.
ATTENTION: DB7002 uses internal Lithium battery. Do not try to re-charge this battery!!!
In case you have to change the battery, please contact us for detailed instructions and more
information for the battery type.

OPERATING ENVIRONMENT RECOMMENDATIONS
For the normal and reliable operation of the DB7002 device and reaching better measurements
we recommend to follow the next list of instructions:
• Please, install the unit only in places with good air conditioning. The unit has been designed
for operation within an ambient temperature range extending from 10 to 50°C. But because
adjacent, less ecient equipment may radiate substantial second-hand heat, be sure that the
equipment rack is adequately ventilated to keep its internal temperature below the specied
maximum ambient temperature.
• We do not recommend installation in rooms with high humidity, dusty places or other
aggressive conditions.
• Although it is expected that a DB7002 will be installed close to exciters (or transmitters of
even higher-power!), please practice reasonable care and common sense in locating the unit
away from abnormally high RF elds.
• Please, use only already checked power supply cables and sources. The shielded cables
usage is strongly recommended.
• We strongly recommend connecting the device only to reliable power supply sources. In
case of unstable power supply, please use UPS (Uninterruptible Power Supply).
• Please, use the device only with placed top cover to avoid any electromagnetic anomalies
which may cause problems of the normal functionality of the unit.
• Please, connect DB7002 only to good quality Internet connection. This is very important for
the normal remote operation of the unit.
• Please, check if your network settings pass through all the data trac required for the
normal operation of the DB7002 unit.

INSTALLATION SPECIFICATIONS AND PRECAUTIONS
REGARDING THE RF ENVIRONMENT.
ANTENNA CONSIDERATION.
Attentively observing of the RF Environment, in which DB7002 is disposed and is functioning,
is necessary for ensuring of the normal and reliable working of the system. Best conditions in
accordance with the standards listed below must be provided for functioning of the system.
Depending on the application, the DB7002 monitoring receiver can be installed very close to
high power FM transmitters. Usually its antenna port is directly connected to any FM transmitter
monitor output or to directional coupler on the output of any combiner system. The typical RF
output level of such sources is too high for the normal operation of the DB7002 receiver. We
strongly recommend using external RF attenuators with attenuation value between 20 – 90dB for
reaching optimal RF output level in the 55-60 dBµV range.
Using external antenna is required when the DB7002 receiver is used for o air monitoring
too far from any transmitters or transmitter site. Very important step in such case is selecting the
proper outdoor FM antenna, antenna location and direction. The three most popular antenna types
are: omni directional, unidirectional dipole and directional multi-element array antenna.
The omni directional Antenna is not a good choice for using with DB7002, because of the low
antenna gain, the very bad signal to noise ratio (compared to any directional antenna) and its high
multipath interferences reception.
The other type antennas: unidirectional dipole and directional multi-element array antenna have
some directivity and antenna gain. These factors make these antennas much proper for your needs.
We recommend the usage of factory made antenna or antenna system, manufactured especially for
the currently selected FM Band - 87.1-108 MHz (CCIR).
After selecting the antenna type that will meet your needs, the next step is the installation of the
antenna. You must follow several important principles:
- Install the antenna far enough from any walls, roofs, buildings or any transmitting equipment;
- The minimum spacing between the antenna and the closest object must be more than 3 meters.
One DB7002 monitoring receiver is usually used for the monitoring of one transmitter site,
transmitting more than one program. In such cases the best antenna that can be used is a directional
antenna directed exactly to this site.
If you would like to monitor more than one transmitter site, we recommend using antenna
system with separate antennas for each of the monitored directions.
