Among the manufacturing techniques of modulator products, some multiplexing techniques are used. One of them is the multiplexer. Among many PBI modulator products, this device has many advantages and features.
1. The modulation circuit adopts today's mainstream modulation chip and is controlled by a single-chip microcomputer, which is stable and reliable.
2. The modulation circuit of each channel is completely independent, and the channel configuration is very flexible and convenient, and the user can request any channel arrangement that is not an adjacent frequency.
3. The output signal is strong. Taking the 32-way modulator as an example, a dual power multiplier module is used to output one line.
4. The power supply has a large amount of redundancy and can work continuously and stably all year round.
5. The relevant debugging of the cable TV transmission equipment has been completed before leaving the factory. It is free of debugging on site. It can work after connecting the power supply and inputting the AV signal. It can be installed and constructed by non-professionals.
6. The multi-channel modulator is integrated and installed, and the structure is compact, and no special machine room is required.
