Description
This is interval channels modulator, it supports NTSC-M/N, PAL-B/G, PAL-DK/I.
The modulator is an analog modulator with frequency separation processing, which can be used in combination with 3 machines to form an analog TV system of 48 programs.
This machine is suitable for small analog TV systems, within 200 TV terminals, if you use an analog TV system with more than 48 channels, it is recommended to use another 16-channel adjacent frequency modulator
1. 16 channels of video and audio channels input, one channel of 16 channels of radio frequency output.
2. It adopts high-IF modulation, one-frequency conversion method and surface acoustic filter processing, and the out-of-band interference is small.
3. The sound, high-IF and RF local oscillators adopt MCU phase-lock technology, which has high frequency stability and accuracy.
4. All functional circuits of the machine adopt chip technology, and the machine has high reliability.
5, easy to operate, factory fixed frequency, can tune the program on its own.
6. Power supply adopts high reliability and high dynamic range switching power supply.
7. Different standards can be customized according to customer requirements.
