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 US TV EXPLORER II 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 optimize 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
transflective 6.5" graphic
TFT display with panoramical format. The equipment
incorporates a light sensor that activates the contrast and luminosity of the display
according to the environmental conditions.
The US TV EXPLORER II is an ideal size to hold with a hand . The instrument
can be held to the body with the carrying bag or transport belt, which at the same time
protects it from the rain. Because it is designed for outdoor use, it includes an
anti-
shock protector that completely covers the instrument, and optionally can be supplied
with a strong transport case. As well, the front panel does not have any keys nor gaps
to avoid accidental water ingress.
The US TV EXPLORER II 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 the commands for the programming of DiSEqC
1.2 and SatCR devices .
The US TV EXPLORER II 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 ,
used in combination with an IF generator to carry out an easy verification of the
installations before commissioning.
The spectrum analyzer features with high accuracy, resolution, sensitivity and
sweep speed allows the instrument to be very useful for applications as the antenna
installation 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 5 or
10dB and the frequency margin span on screen.
