1.1 Description
The television explorer US TV EXPLORER II represents an evolutionary step with
respect to the traditional field strength meters. The continuous PROMAX innovation
process in the sector of field strength meter yields an instrument that changes the way
to take and understand television signals measurements.
This equipment incorporates important advances in the functional aspects as
well as in the ergonomics to allow the installers to make their work with maximum
comfort and speed. Simultaneously the instrument is reliable for any possible problem
at the input signal, at the distribution components or the receiver equipment.
The US TV EXPLORER II has been designed to satisfy all the necessities of
measurement during the transition from the analogue transmissions to digital in
terrestrial, satellites and cable systems. Allowing measurements of analogue signals
as well as digital ones. When pressing the auto identification key, it searches and
identifies the signal under test. First it recognizes whether the signal is an analogue
channel or a digital one. When the signal is digital (ATSC, DVB-S/S2,ITU-T J.83/B,
DVB-C, DSS), it analyses for each modulation type 8-VSB / QAM
ANNEX-B / QPSK / 8PSK all the associated parameters: symbol rate, code rate, etc.
and determines the value of the signals under test.
The range of frequencies covered makes this instrument an excellent tool for FM
radio, terrestrial TV, mobile TV, satellite TV and cable TV (where the subband tuning
margin, from 5 to 45 MHz, enables the user to carry out tests on the return channel).
The US TV EXPLORER II adapts itself to the characteristic parameters of the
standard and to the correct automatic system in order to obtain in all the cases an
accurate measuring of the input signal level. It accepts the NTSC TV system and allows
the user to work directly with digital TV signals decoding them, so that the television
image may be viewed, and directly measuring the power, carrier/noise ratio (C/N), the
bit error rate (BER) and the modulation error ratio (MER), as well for ATSC (8-VSB) as
DVB-S (QPSK), DVB-S2 (8PSK), DSS (QPSK), DBV-C (QAM Annex-A) and ITU-T
J.83/B (QAM Annex-B) signals. This instrument allows to obtain besides a graphical
representation of the Constellation Diagram for DVB-S/S2 (QPSK/8PSK),
DVB-C(QAM) and ITU-T J.83/B (64/256-QAM) signals.

USER’S MANUAL. US TV EXPLORER II
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.

USER’S MANUAL. US TV EXPLORER II
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. The equipment is
able to generate automatic measurement reports and to update itself through Internet
by means of PkTools provided software.
Also, this meter incorporates a DiSEqC
2
command generator and permits to
supply different voltages to the external unit (5 V / 13 V / 15 V / 18 V / 24 V) and
includes a SCART-RCA adapter, for audio/video input/output.
The US TV EXPLORER II is powered by rechargeable battery or connected to
the mains through the supplied external DC power charger.
It incorporates a USB port, which enables the communication with a PC and to
download dataloggers and channel plans.
This instrument due to its extreme-compact design, technical specifications and
low cost becomes the industry standard for the installer.

depends on the condition of the battery. If they are very low the recharging period is
about 5 hours. The CHARGER [4] indicator should remain lit.
When the battery charging process is completed with the instrument off, the fan
stops.
IMPORTANT
The instrument battery needs to be kept charged between 30% and 50% of its
capacity when not in use. The battery needs to be fully charged for best results. A
fully charged battery undergoes temperature-related discharge. For example, at a
room temperature of 20 °C, it can lose up to 10% of its charge over 12 months.
