A signal generator compatible with the multimedia broadcasting "ISDB-Tmm" system. It can generate signals for 33 segments compatible with ISDB-Tmm.
This device is a signal generator compliant with ISDB-Tmm, adopted for multimedia broadcasting for mobile terminals. It incorporates a TS generation unit, modulation unit, RF converter unit, and noise generation unit, making it suitable for the development and production of receivers. Equipped with multiple functions, it can play MPEG2 TS from an internal HDD or input from external sources. It can simultaneously generate multiple segment signals in 1-segment, 3-segment, and 13-segment formats, and can produce a maximum of 33 segment concatenated signals. An optional fading simulator and BER measurement device can be installed.
