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.

Frequency Synthesiser
RA062-F2
-
The RA062-F2 is a multiple LO module used to generate three pairs of LO signals, each pair being phase matched in order to provide the capability to drive two phase and amplitude matched, high sensitivity narrowband receivers such as might be required for an EW receiver system with DF functionality.The Stepped Frequency Synthesiser is based upon Direct Frequency Synthesis, DFS, whereby the 1GHz input reference signal is multiplied, filtered and mixed to generate a given number of isolated and filtered single tone CW signals from the 1GHz comb. A finely tuned signal is then generated using a multi-way switch to select between the 1GHz spaced CW tones and mixed with fine resolution signals generated using a custom DDS/VCO PLL network. In this way finely tuned signals can be generated between 7.5GHz and 23GHz.
