ADVANTEST Digital TV Signal Analyzer R3466

DESCRIPTION

The R3466/3466N Digital TV Signal Analyzers are high-performance signal analyzers that integrate the measurement functions and performance required for the installation and maintenance of

It is a high-performance signal analyser that integrates the measurement functions and performance required for reception evaluation of digital terrestrial broadcasting (ISDB-T) standards, CATV transmission systems and transponder installation and maintenance. Real-time demodulation

The BER-100 is equipped with a real-time demodulation function and a built-in noise source (optional), making it an indispensable tool for the reception evaluation of digital broadcast waves.

The BER measurement, signal C/N measurement and noise margins, etc., required for reception evaluation of digital broadcast waves, can be easily performed with this unit,

noise margin, etc., which are indispensable for the evaluation of digital broadcast reception.

On-Air BER measurement

The built-in ISDB-T real-time demodulator enables On-Air BER measurement using signals being broadcast. (Patent pending)

The indicator for evaluating the transmission quality of digital transmission is the bit error rate.

In digital television broadcasting, BER measurement in non-operational conditions

in non-operational conditions in digital television broadcasting can be measured using conventional PRBS signals, but measurement in operational conditions (during broadcasting) is not possible.

（The R3466/3466N is a new system that uses null packet BER measurement to evaluate the bit error rate.

The R3466/3466N enables BER measurement in operational conditions by measuring BER using null packets.

Noise margin measurement

Error correction technology in digital terrestrial broadcasting can provide clear images up to the required BER value.

While the error correction technology in digital terrestrial broadcasting can provide clear images up to the required BER value, it is not possible to determine the system's noise margin from the received image.

However, it is not possible to determine the system's noise margin from the received image. Traditionally, complex equivalent noise

degradation (END) and noise margin (NM) have traditionally been used in conjunction with noise generators, variable attenuators, mixers, etc.

Traditionally, complex equivalent noise degradation (END) and noise margin (NM) have been measured using a system of noise generators, variable attenuators, mixers, etc., OFDM demodulators and BER measurement equipment.

The R3466/3466N is a simple and easy to use system that only requires the addition of a noise generator (option).

The R3466/3466N can be operated easily and quickly by simply adding a noise generator (option).
