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.


Instructions for Use:
  1. Electricity Supply:  Before using the external power adapter to supply power to the equipment, confirm that the housing is well grounded before connecting the power supply; after the power is connected, the alarm status light and power indicator light in the machine are lit to indicate that the power is normal.
  2. 2,Input fibre optic connection:Disconnect the power supply and use lens paper dipped in anhydrous alcohol to connect the input optical fiber to the optical fiber adapter (FC/APC or SC/APC). When winding the fiber, ensure it is not too bent. Under the condition that the input optical power does not exceed 2mW (3 dBm), reconnect the power supply; the power indicator light should illuminate. The digital display should show the current optical power. If the received optical power is lower than or below the displayed LO or if the "Optical" red light is on, you can perform a power measurement test. Under normal circumstances, this value should be consistent with the actual measurement from an optical power meter. Otherwise, wipe the fiber optic connector.
3,Output level adjustment:This machine in +3dBm to -6dBm optical power input, the standard configuration of the whole machine output level of 106dBV. correct input optical signal, in the output port of the field intensity meter to detect the level of value, can be adjusted by adjusting the attenuation position on the size of the attenuator fixed attenuator attenuation amount to adjust the size of the whole machine's output level; appropriate setting of the tilt of the output level can improve the distortion characteristics of the RF transmission, the machine in the The slope of the output level is set to 0dB when it is shipped from the factory, as long as you adjust the fixed attenuation value on the position of 'tilt', you can set the slope of the level of the whole machine to a specific value (the slope is adjusted by means of a fixed attenuator to achieve this); this machine can also be used according to the actual needs of different networks. In the process of using, you can use the -20dB test port corresponding to the output port to carry out online measurement and maintenance without interrupting the downstream output.
