UPCONVERTER 10 GHz LXI
-
UPCONVERTER 10 GHz осуществляет программно управляемый перенос вверх спектра шириной 150 МГц, поступающего на вход сигнала, в любую точку спектрального диапазона от 10 МГц до 10 ГГц. Перенос спектра осуществляется по супергетеродинному принципу с тремя ступенями переноса. Благодаря этому во всем рабочем диапазоне спектра достигаются высокие уровни подавления несущей частоты и зеркального канала. Также UPCONVERTER 10 GHz обладает уникальной возможностью, не имеющей аналогов среди приборов подобного типа – задавать значение промежуточной частоты (входного сигнала) для переноса в диапазоне от 50 до 400 МГц. Помимо этого, прибор позволяет передавать входной сигнал частотой от 0,1 до 400 МГц напрямую на выход, без переноса. Благодаря этому, совместно с UPCONVERTER 10 GHz в качестве генератора промежуточной частоты может быть использован широкий спектр генераторов зарубежного и отечественного производства. Холдинг «Информтест» предлагает потребителям генераторы собственной разработки MGKS and MGVCh , as well as the first Russian MT transceiver module , which are fully compatible with the input characteristics of UPCONVERTER 10 GHz. Together with generators produced by the holding "Informtest" UPCONVERTER 10 GHz under the control of a common software shell makes up a synthetic instrument - a ready-made solution for testing microwave devices and radio reception channels.
