Note: Under the fixed link loss, 550 MHz has 59 PAL-D channel analog TV signals. Among 550 MHz to 862 MHz, every 2 MHz band transfer the digital modulation signals. It is tested when the digital modulation signal level is 10dB lower than analog modulation signal level and the optical receiver input optical power is -1dBm. Test results will differ according to the different hybrid module. Pls refer to the user manual for details.
