Microprocessor-controlled double-sideband modulator. Output channel selection is made using two buttons (visible after opening the cover), and its number, like each editable parameter described below, is displayed on the LED display. The channel number and other parameter values are saved in non-volatile memory. The use of a quartz stabilization circuit (PLL) ensures near-zero frequency error. These modulators can be cascaded. They also allow for summing the modulated signal with the terrestrial television signal. The modulator can be secured against unauthorized access. It should be noted that, compared to previous modulator series, Terra has implemented more PAL system variants. & xa0. Inputs: 1 pc. Composite video (Cinch), 1 pc. RF (F), 2 pcs.
