RTX100A ISDB-T RF Signal Generator Service Manual
1-7
Table 1-2: Mainframe (Cont.)
Characteristics Description
Digital modulation
Standard ARIB B31 V1.1
Mode 1/2/3
Bandwidth 6 MHz
Number of segments 13
Number of layers Maximum 3
Carrier modulation QPSK, 16 QAM, 64 QAM
NOTE: DPQSK is not supported. If DPQSK modulation is used in a broadcast transport stream,
the stream is modulated into QPSK. However, the signal output from the ASI connector is not
modulated into QPSK.
Inner coding Vitervi (1/2, 2/3, 3/4, 5/6, 7/8)
Outer coding Reed Solomon (204, 188)
Time interval 0,1, 2, 4, 8, 16
Guard interval 1/4, 1/8, 1/16, 1/32
UHF output
Frequency 470 to 770 MHz (channel plan steps)
