It enables to record an MPEG-2 TS, in which signals required for audio/video tests of Digital IRD (DIRD) and Set Top Box (STB) are multiplexed, and an ISDB-S TS having a frame configuration in which TMCC of BS digital broadcast is multiplexed, in the built-in hard disk drive (HDD). The recorded signals can continuously be output at the designated bit rate. By combining the TG73A, ShibaSoku's RM73A satellite digital modulator which can cope with a wide-range bit rate and features good versatility and expansion and ShibaSoku's RC931A synthesized frequency converter, you can obtain compact "ISDB-S central digital signal source system". The RM73A is a Satellite Digital Modulator which conforms to both the BS (ARIB STD-B20) and CS (DVB-S) systems used in Japan. In the BS system mode, the modulation system can be switched automatically using TMCC information. Features Selection of BS or CS system mode. In BS mode, which conforms to the BS digital broadcasting standards (ARIB STD-B20) used in Japan, the modulation system can be switched automatically using TMCC information. In the CS mode, a wide range of bit-rate input conforming to the DVB standards can be input. The TS packet length can be changed to 188 Bytes, 204 Bytes, or 208 Bytes (only with the BS system). Digital waveform shaping filter allows to select root-cosine roll-off characteristics featuring 35% roll-off ratio or cosine roll-off characteristics. The RC931A is a Synthesized Frequency Converter for ShibaSoku's modulator, converting IF frequencies of 140.00 MHz to anywhere from 30.00 to 2400.00 MHz. Features Designed for use with digital modulators. The local oscillation unit uses a low phase noise frequency synthesizer. V channel frequencies in the VHF and UHF, No.1 IF (BS-1) band of satellite broadcasting. - Frequency range: 30.00 to 2400.00 MHz - Minimum step: 10 kHz Output level can be freely set within a range of 0 to -100 dBm in 1 dB increments.
