Description

The television explorer US TV EXPLORER
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 functional aspects as well as
in ergonomic to allow installers to make their work with maximum comfort and speed.
Simultaneously the instrument is reliable facing any possible problem relating to input
signals, distribution components or receiver equipment.
The US TV EXPLORER
measurement during the transition from the analogue to digital transmissions 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 analyzes for each modulation type 8-VSB / QAM
/ 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 by this instrument it makes 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
standard and to the correct automatic system in order to obtain in all the cases an
accurate measurement 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 obtaining 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.
