Test Condition:
Configure 59 PAL-D analog channel signals at the 550MHz frequency range. Transmit digital signal at the frequency range of 550MHz～862MHz. The digital signal level (in 8 MHz bandwidth) is 10dB lower than analog signal carrier level. When the input optical power of the optical receiver is -1dBm, the output level: 108dBμV, EQ: 8dB.
