More are more programs are being added into existing CATV system, which requests addition of modulators. To meet such demand, JIUZHOU develops the modulator TZJ860-B which is of adjacent and has agile frequency output.
TZJ860-B adopts high performance modulating IC, and employs a microprocessor unit to monitor working parameters & enable control/configuration. Working parameters and status could be viewed on the LCD display built on front panel. Output frequency, output RF level and A/V ratio are configurable.
Adjacent modulator with agile frequency output.
47~863MHz output frequency range.
SAW filtered, providing good differential gain and differential phase performance.
Built with IF input and IF output.
PLL technology for both RF Local Oscillator and audio, ensuring good stability and high accuracy.
Employs a microprocessor unit to monitor and control working status/parameters: (1) Output frequency configurable. (2) Output frequency deviation adjustable, 0.125MHz/step. (3) Accurate control over RF output level and A/V ratio, 0.5dB/step.
LCD display built on front panel to show operating menu and working status/parameters.
Standard 19' 1RU chassis.&
