Promax PRODIG-3 Manual Del Usaurio página 78

Being a multistandard instrument, it can be efficiently used in any country of the
world.
Includes a symbol-based keyboard that allows the direct access to the various
functions that are displayed simultaneously on screen.
The PRODIG-3 makes a dynamic exploration of the spectrum, detecting all the
channels in the explored band, this applies for the terrestrial and the satellite
television bands. The meter locates all the channels in the spectrum with no need of
any previous information about the number of channels, the type of signals
transmitted or their characteristics. With the data collected after each exploration, it
creates a register that contains tables of channels that can be independent for each
system or installation. At any time, the measurement sessions using only the
pretuned channels can be repeated. In this way it is possible to optimise the
measurement process.
Shown on the frontal panel is the type of measurement that is being carried
(Terrestrial-Satellite/Analogue-Digital) and the data are presented on a hi-res 4" graphic
TFT display. The equipment incorporates a light sensor that activates the contrast and
luminosity of the display according to the environmental conditions.
The PRODIG-3 is designed to integrate measurements that require different
operating configurations. In this way it incorporates a specific function to facilitate the
alignment of antennas. When activating the alignment function the instrument is set
automatically to offer a fast spectrum sweep and a high sensitivity graphical bar that
allows fine adjust for the maximum signal. In addition it includes a module for the
powering of LNBs and DVB-T antennas to 5 V, and the commands for the
programming of DiSEqC 1.2 devices.
The PRODIG-3 can be updated to new software versions that extend the
available functions in the future. That means it can incorporate new benefits without
additional cost. For example in the test of satellite signals distribution networks, the
use in combination with an IF generator to carry out an easy verification of the
installations before the operation begins.
The spectrum analyser features with high accuracy, resolution, sensitivity and
sweep speed allows the instrument to be very useful for applications as the installation
of antennas or the detection of complex impulsional noise events. It presents an
innovative control system based on four arrows, that makes the use of the spectrum
analyser very intuitive. The arrows allow adjusting the reference level by steps of
10 dB and the frequency margin span on screen.
To enhance its convenience of use, it includes memories to store automatically
the different data acquisitions, i.e.: acquisition name, test points, frequency, channel
plan, etc.,. Moreover, the DATALOGGER function makes it much easier to test systems
in which a large number of measurements have to be made, and enables further
processing of all the information acquired using a computer system.
