| Note：
In the the condition of stipulated link-loss, configurate 59 PAL-D analog television channel signals within 550MHz frequency, in the range of 550MHz ~ 862 MHz frequency transmit digital modulation signals, digital modulation signal level ( in 8MHz bandwidth) is 10dB lower than the analog signal carrier level,when the optical input power is 0dBm, you can measure the carrier combination triple beat ratio (C / CTB), carrier combination of second-order beat ratio (C / CSO) and the carrier to noise ratio |
