Double-band modulator with microprocessor control
The output channel is selected using two buttons (visible after opening the cover), and its number, like any parameter described below, the value of which can be changed, is displayed on the LED display
The channel number and the values of other parameters are saved in non-volatile memory
The use of a quartz stabilization system (PLL) ensures almost zero frequency error
These modulators can be cascaded
They also enable summing of the modulated signal with the terrestrial television signal
It is possible to protect the modulator against unauthorized access
It should be noted that compared to the previous series of modulators, Terra has implemented more variants of the PAL system
