What are the main features of the modulator?
1. The modulator uses the PAL-D standard adjacent channel modulation in the 48MHz-750MHz band to fix the channel output.
2. The idea of designing a double-phase-locked loop (PLL) CPU with image frequency and audio frequency on the circuit design.
3. Imported high-quality broadcast-grade modulation chips (TOSHIBA, MOTOROAL, INTECH, TEXAS INSTRUMENTS, FAIRCHILD, etc.) are used on the device.
4. Using high-performance surface acoustic wave (SAW) filtering, the residual sideband suppression is greater than 65dB.
5,110 dBuv RF output, stable level amplitude, accurate frequency.
6. Unique filtering method, with out-band output suppression greater than 65dB.
7, image modulation, audio frequency offset, A / V ratio, RF output level can be adjusted.
8, 19 inch standard chassis design, standardized installation.
