The TV EXPLORER HD ISDB-T/T
B
has an HDMI connector ( H igh- D efinition M ulti-
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 ISDB-T/T
B
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 from the auxiliary TS . 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 (
ISDB / DVB ), it analyses for each modulation type QAM / QPSK / 8PSK
the associated parameters such as the modulation system: 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).
It accepts NTSC and PAL-M and N TV systems 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 ISDB-T/T
B
( COFDM ) as DVB-
S/S2 (QPSK/8PSK) and DVB-C/Annex-B (QAM) signals. This instrument allows to
obtain a graphical representation of the Constellation Diagram for DVB-C/Annex-B
(QAM) , ISDB-T and DVB-S/S2 (QPSK/8PSK) signals.
As a multistandard instrument, it can be used in any country that uses the
ISDB-T standard, like Brazil, Venezuela, Chile, Japan, etc...
Includes a symbol-based keyboard that allows the direct access to the various
functions that are displayed simultaneously on screen.
The TV EXPLORER HD ISDB-T/T
B
makes an exploration of the spectrum,
detecting all the channels in the explored band, this applies for the terrestrial and the
satellite television bands. The spectrum exploration is made on the channel plan that is
selected, and creates a new channel plan with new found parameters for each channel.
