DOWNCONVERTER VXI 10 GHz

DOWNCONVERTER

DOWNCONVERTER 10 GHz provides a transfer (controlled by software) of a spectrum bandwidth of up to 150 MHz, which is received at a signal input, to any point of spectrum bandwidth from 10 MHz to 10 GHz. A spectrum transfer is based on superheterodyne principle with three stages of the down-conversion. Due to this feature, a high levels of carrier frequency suppression (up to -80 dBc) and of mirror channel suppression (up to -90 dBc) is achieved in the entire operating frequency range. Also DOWNCONVERTER 10 GHz has a unique feature to set the value of an output intermediate frequency in the range from 75 MHz to 400 MHz. This feature isnt presented in other devices of similar type. In addition, the device can transmit an input signal frequency from 10 to 400 MHz to an output without conversion. Due to presence of this feature a wide range of Russian and foreign made ADCs can be used as a digitizer by combining with DOWNCONVERTER 10GHz. Holding Informtest offers to customers MOS1 and MOSC6 digitizers designed and manufactured by Informtest, as well as the first Russian transceiver module MT-1, which are fully compatible with the input characteristics of the DOWNCONVERTER 10 GHz. The DOWNCONVERTER 10 GHz along with digitizers manufactured by holding Informtest, controlled by common software shell, presents a synthetic instrument - a turnkey solution for testing of RF devices and radio channels.

Design of the DOWNCONVERTER 10 GHz assumes it to be used in enclosed mobile complexes used for field tests of communication equipment. For this purpose the instrument utilizes advanced solutions for an output signal phase noise reduction under conditions of increased vibrations and high temperature. The device has a temperature stabilized reference oscillator with ability to output a reference frequency signal. The instrument can also be used with external reference signal generator.

The control software of the DOWNCONVERTER 10 GHz is made in the standard VXI Plug & Play and independent of the version of the module. The software allows for automated calibration and verification of devices main characteristics.
