Note 1: Configure 6 PAL-D analogue TV channel signals in the frequency range of 112.25 MHz-152.25 MHz, and transmit 87 digital modulated signals in the frequency range of 203 MHz-898 MHz. The level of the digital modulated signals (in the bandwidth of 8 MHz) is 6-10 dB lower than that of the analogue signals on the carrier, and the optical power input to the optical receiver is -9 dBm. C/CTB, C/CSO and C/N are measured when the optical power input to the optical receiver is -9 dBm.
