Description
DP-8MA agile modulator is a space saving, agile channel modulator system. It consists of 8 individual, vertically y mounted, agile frequency modulators and an efficient switching type power supply module. It is designed for 19 inch rack mounting.
 
Each modulator is SAW filtered and be able to be set within 47 MHz ~860MHz by user. Precise frequency is maintained with PLL circuitry. It offers excellent video performance and high reliability.


 
Features
  • 8 audio/video input, one RF output from 45-550MHz or 47-860MHz, double side band).
  • Intermediate frequency, twice conversion frequency and with SAW filter, low side-band interfere.
  • MCU technique is applied to audio intermediate frequency, video high frequency process and RF local oscillator, with high stability and accuracy.
  • Integrated circuit is applied to outputs, abd each functional circuit of the overall unit adopts SMT technology, with high security.
  • LED displays frequency, using up and down botton to select any preference frequency or channel.
  • Convenient control, all frequency level adjustments on front panel.
  • High efficiency power supply.
  • We can make different TV system standard according to the customers need
