Description

The television explorer PRODIG-3 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 PRODIG-3 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 QPSK /
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 PRODIG-3 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 (COFDM) and DVB-S
(QPSK) signals.
