Double sideband modulator controlled by a microprocessor. The choice of output channel is performed with two buttons (after opening the top cover), and the channel number or any changeable parameter is displayed on the LED display. Channel number and other parameters values are stored in non-volatile memory. Use of quartz-stabilized PLL practically eliminates frequency error. The modulators can be connected in cascade. They also enable combine modulated signals with terrestrial TV signal. There is a possibility to protect the modulator against unauthorized access. Please note, in comparison to the previous series, these Terra modulators can provide compatibility with many versions of the PAL system.
