Product Description
The Tektronix RFM220 ISDB-Tb Measurement Demodulator provides the
means to measure and monitor signal performance for signals conforming to
the Brazilian and Japanese ISDB-Tb terrestrial Digital TV standard.
The RFM220 demodulator can measure MER in real time, commonly
considered a key
fi
gure for qualifying a transmitting system. The input to the
RFM220 demodulator can be an RF signal or an ASI stream. The software
interface displays measurement traces, signal spectrum, and constellation
and lets you con
fi
gure and control the instrument using a local or remote
Ethernet connection.
Installed at a transmission site, the RFM220 demodulator can continuously
monitor in real-time the essential signal performance
fi
gures such as input
level, MER, shoulder levels, and error rate ratio. The ASI output on the
RFM220 demodulator can output either the ASI input signal or the RF
demodulated signal to feed an external video/audio decoder or a transport
stream analyzer such as the Tektronix MTS400A MPEG Test System.
The RFM220 demodulator can be used as a standalone RF monitoring solution
or used in conjunction with a Tektronix MTM400A DTV monitor to provide
combined RF and TS monitoring. (See page 75,
