Note: Under the specified link loss conditions, configure 59 PAL-D analog TV channel signals within the 550MHz frequency range, and transmit digital modulation signals within the 550 MHz to 862MHz frequency range. The level of the digital modulation signal (within an 8 MHz bandwidth) is 10dB lower than the carrier level of the analog signal. When the optical receiver input optical power is-6 dBm, measure C/CTB, C/CSO, and C/N. The nominal RF output level is at the 862 MHz frequency point, with the actual output being 10dB lower.
