1 GENERAL
1.1 Description
The television explorer TV EXPLORER HD / HD
LE represents an evolutionary step
with respect to the traditional field strength meters. This new jewel of the PROMAX
range will become a reference in the industry for being the very first meter of its kind to
actually meet the requirements to be called a real HDTV instrument. 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 .
Millions of people in Europe are now served with digital TV broadcasting only.
Analogue switch off is history for them. For these and those who still are in the migration
process from analogue to digital, the use of digital TV distribution equipment will be more
frequent every day. The typical high definition formats used in nowadays broadcast are
1080i (1920x1080 pixels) and 720p (1280x720 pixels). Most of the TV programmes
using these video resolutions are being broadcasted compressed in MPEG-4. The
TV EXPLORER
HD / HD
LE is able to display those TV programmes thanks to its state of
the art electronics.
HDTV content is expensive to produce and therefore it is usually protected by
encryption. Once again the TV EXPLORER
HD / HD
LE is setting new standards with its
CAM interface that allows the encrypted high definiton programmes to be displayed as
well.

USER’S MANUAL. TV EXPLORER HD / HDLE
The TV EXPLORER HD has an HDMI

connector (High-Definition Multi-media
Interface) which allows the use of standard, enhanced or high definition video, as well as
8 audio digital channels without compression. With no doubt, it will become the digital
replacement for analog standards such as the Euroconnector (SCART).
The TV EXPLORER
HD also has a DVB-ASI

standard interface, which allows
both the input and output of transport streams. Automatically detects whether the stream
is composed by 188 or 204 bytes, and can transmit data in packet mode or burst mode.
You can select the input you want to decode between the external ASI and the internal
demodulator, and what data you want in the ASI output, either from the demodulator or
the CAM module. Therefore, to have TS-ASI inputs and outputs becomes an essential
feature for a TV analyzer ready for the future.
When pressing the auto identification key, it searches and identifies the signal
under test. First it recognises whether the signal is an analogue channel or a digital one.
If the channel is analogue, it determines the television standard of the signal. When the
signal is digital ( DVB ), it analyses for each modulation type QAM / QPSK / 8PSK /
COFDM all the associated parameters such as the modulation system: carriers 2k-8k,
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 TV EXPLORER
HD / HD
LE includes the main TV standards : M , N , B , G , I , D ,
K and L , adopting, apart from the characteristic parameters of the standard, the
correcting automatic system to obtain in all the cases an accurate measuring of the input
signal level. It accepts any TV system ( PAL , SECAM and NTSC ) 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 DVB-T/H (COFDM) as
DVB-S/S2 (QPSK/8PSK) and DVB-C (QAM) signals. This instrument allows to obtain a
graphical representation of the Constellation Diagram for DVB-C (QAM) , DVB-T/H
(COFDM) and DVB-S/S2 (QPSK/8PSK) signals .
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.

USER’S MANUAL. TV EXPLORER HD / HDLE
The TV EXPLORER HD / HD LE 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 6.5" colour
graphic TFT transflective display with panoramic aspect ratio (16:9). The equipment
incorporates a light sensor that activates the contrast and luminosity of the display
according to the environmental conditions.
Furthermore the TV EXPLORER
HD / HD
LE comes with a conector for CAM
modules (PC-Card) that allows the insertion of subscriber conditional access cards.
The TV EXPLORER HD / HD
LE 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 is supplied with a strong
transport case. As well, the front panel does not have any keys nor gaps to avoid
accidental water ingress.
English
The TV EXPLORER HD / HD
LE 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 5V, and the commands for
the programming of DiSEqC 1.2 and SatCR devices .
The TV EXPLORER
HD / HD
LE 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 , using combined with an IF generator permits to carry out an easy verification
of the installations before commissionning.
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 . 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 or 5 dB and the frequency margin span on screen.

USER’S MANUAL. TV EXPLORER HD / HDLE
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.
The TV EXPLORER
HD / HD
LE in addition, allows to record and play one service
from the TS of the digital channel that is being demodulated by an internal memory up to
1 GB.
Also, this meter incorporates a DiSEqC

depends on the condition of the battery. When the instrument is in operation the
recharging process is slower. 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 suffers temperature-related discharge. For example, at a room
temperature of 20 q C, it can lose up to 10% of its charge over 12 months.
