Description

Double sideband modulator MT-47 is controlled by a microprocessor - the choice of output channel is performed with two buttons (after opening the top cover). The channel number or any changeable parameter is displayed on the LED display and stored in non-volatile memory. Use of quartz-stabilized PLL practically eliminates frequency error. There is a possibility to protect the modulator against unauthorized change of the preset parameters.
