1GENERAL
1.1 Description
The television explorer TV EXPLORER II / 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 TV EXPLORER II / 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 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).
TV EXPLORER®is a registered trademark PROMAX Electronica S.A.

The TV EXPLORER II/II+ includes the main TV standards: M, N, B, G, I, D, Kand
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.
The TV EXPLORER II / 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 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 II+ comes with a conector for CAM modules
(PC-Card) that allows the insertion of subscriber conditional access cards.
The EXPLORER 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 II / 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 DVB-T antennas to 5V, and the commands for
the programming of DiSEqC 1.2 and SatCR devices.
The EXPLORER 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 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 or
5 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. The equipment is
able to generate automatic measurement reports and to update itself through Internet by
means of PkTools provided software.
The TV EXPLORER II+ in addition, allows to record and to play a TS
corresponding to services from a digital channel. For it, the equipment uses an internal
memory of up to 1 GB.
Also, this meter incorporates a DiSEqC2command generator and permits to
supply different voltages to the external unit (5 V / 13 V / 15 V / 18 V / 24 V) and includes
an EUROCONNECTOR, or Scart connector, for audio/video input/output.
The TV EXPLORER II / 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.

3INSTALLATION
3.1 Power Supply
The TV EXPLORER II / II+ is a portable instrument powered by one 7.2 V Li-Ion
battery. There is also an external DC charger provided for mains connection and battery
charging.
3.1.1 Operation using the External DC Charger
Connect the external DC charger to EXT. SUPPLY [32] on the
TV EXPLORER II / II+ side panel. Connect the DC charger to the mains. Then, press the
rotary selector [1] for more than two seconds. The level meter is now in operation and
the battery is slowly charged. When the instrument is connected to the mains, the
CHARGER indicator [4] remains lit. This indicator changes of colour according to the
battery charge status:
BATTERY CHARGE STATUS
OFF ON
RED < 50 % < 90 %
YELLOW > 50 % > 90 %
GREEN 100 % 100 %
Table 1.- Indication of the battery charge status (CHARGER).
3.1.2 Operation using the Battery
For the device to operate on the battery, disconnect the power cable and press the
rotary selector [1] for more than two seconds. The fully charged battery can power the
equipment for more than 4.5 hours non-stop.
If battery is very weak, the battery cut-off circuit will prevent the device from
functioning. In such a situation battery must be recharged immediately.
Before taking any measurements, you have to check the charge status of the
battery by checking the battery charge level indicator that appears when activating the
measurement mode pressing key [12]. These are the indicators on screen:

Recharge in progress.
Table 2.- Indication of the battery charge level on screen.
3.1.2.1 Battery Charging
To fully charge the battery, connect the instrument to the external DC charger
without activating the power on process. The length of time it takes to recharge it
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 ° C, it can lose up to 10% of its charge over 12 months.
3.2 Installation and Start-up
The TV EXPLORER II / II+ level meter is designed for use as a portable device.
Therefore does not require installation
When the rotary selector [1] is pressed for more than two seconds, the instrument
is started up in the automatic power-off mode; that is, the device is automatically
disconnected after the selected minutes if no key has been pressed. When the device is
operating, it is also possible to select the auto power-off mode by means of the
Preferences menu [22] and to select the time out until the automatic power-off.
When the equipment is going to be moved, activate the Transport mode by
means of the Preferences menu [22] to disable the power on process until one specific
