Phase-Coherent «MIMO» Acquisition and Generation System
The developed system is designed for multichannel phase-coherent RF signal acquisition and generation. It allows to continuously record a signal with a bandwidth of 50MHz and playback with a bandwidth of 100MHz, which can be used for recording in electromagnetic environment for the further playback in laboratory conditions.
With this system it is possible to make measurements of a phase shifter, delay lines, as well as to make active phased array antenna calibration.
The system is based on the NI PXI platform and can be configured for two or more channels of phase-coherent signal acquisition. The software is developed in the NI LabVIEW graphical programming environment, which has a simple and user-friendly interface.
