The TV EXPLORER
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
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
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.
