ProductName: AV4023 Portable Microwave Spectrum Analyzer
LastModiDate:2012/5/11 11:01:41


AV4023 Portable Microwave Spectrum Analyzer is the new generation portable microwave spectrum analyzer developed by our 41st institute using broadband microwave component integration design technology, microwave multilayer PCB design technology, efficient voltage transformation system design technology and multi-band sweep & individual thread processing technology. Compared with the last generation product, its frequency range increases by 5 times, display average noise level decreases by 20dB, single sideband phase noise decreases by 20dB and measuring speed increases by 4 times, featured by broad frequency band, high performance index, small size, light weight, flexible power supply and easy maneuvering, suitable for field service.
Available in the frequency range 1MHz ~ 18GHz, AV4023 Portable Microwave Spectrum Analyzer can meet the need of measurement from short-wave through to wave band Ku. It uses menu-type operation interfaces and graphical display of measurement result, which operation is simple and result is direct viewing. Portable microwave spectrum analyzer is internally built with a large-capacity FLASH memory and supports USB external memory by which the field measurement curves can be stored for subsequent analysis and processing and filing up for management.

AV4023 Portable Microwave Spectrum Analyzer is mainly used in the development, repair and maintenance etc. various sectors of radar and communication equipment as well as by the spectrum monitoring and management department for spectrum monitoring and management.
